Abstract
The composition based on fluorochlorohydrocarbon contains a surface active agent resulting from the reaction of a quaternary ammonium chlorhydrate with an alkyl phosphoric acid in the presence of a fluor-containing amine and a carboxylic acid. The separation rate of the aqueous and organic phase is improved.
Description
'•> b i> !. PATENTS ACT, 1964 COMPLETE SPECIFICATION WATER-REMOVING COMPOSITION BASED ON FLUOROCHLORO-HYDROCAR3GN AND SURFACTANT ATOCHEM, a French Body Corporate, of 12-16 Allee des Vosges, 92 400 COURBEVOIE, France. — 1 — Sfiti'j L 2 The present invention relates to a composition which can be used, in particular, for removing water present on a wet surface.
Water-removing compositions of various types have 5 been described. Such compositions generally contain a fluorochlorohydrocarbon, more specifically 1 , 1 , 2-trichloro-1,2,2-trifluoroethane, and one or more surfactants, for example an alkyl phosphate neutralised by means of an amine, an amine salt, a diamide, where appropriate in the presence of a carboxylic acid or a cationic imidazoline surfactant, or alternatively a surfactant resulting from the reaction of quaternary ammonium chloride with an alkylphosphoric acid in the presence of a fluorinated amine (see European Patent 83/400293.3).
The present invention relates to an improvement in the compositions described in the said European Patent, the improvement being in respect of the rate of separation of the aqueous phase from the organic phase during the removal of the water.
More specifically, the invention relates to a water-removing composition which can be used for displacing '3 Liquid water, the said composition containing a solvent consisting of at Least 50% by weight of a c h I o r o f I uo ro-hydrocarbon and a surfactant resulting from the reaction of a quaternary ammonium chloride of formula: (R>2^ + ^N (R ' ) 2 CI (_) (I) with an alkyl phosphoric acid of formula: (R"0)p (H0)2-p PO2H CII) in the presence of a fluorinated amine of formula: Rp XNR-j R2 (III), in which formulae Rp denotes a linear or branched perfluori nated chain Cq^q + V in which q is an integer between 2 10 and 20, X is a bivalently bonded group, optionally partially halogenated, R is an alkyl group having 6 to 18 carbon atoms, R' is an alkyl group having 1 to 2 carbon atoms, R-j and R2, which may be identical or different, denote a hydrogen atom, an alkyl radical or a hydroxyalkyl 15 radical having from 1 to 8 carbon atoms, and R" is an alkyl group having from 1 to 18 carbon atoms, the said composition being characterised in that it contains at least one carboxylic acid chosen from saturated linear, branched or cyclic aliphatic mono- or diacids having 20 from 5 to 10 carbon atoms, and optionally substituted; unsaturated linear or branched aliphatic mono- or diacids having from 5 to 30 carbon atoms and optionally substituted; and aromatic acids having from 7 to 9 carbon atoms, optionally mono- or polysubstituted with amino, 25 nitro, hydroxy or methoxy groups.
The compositions according to the invention advantageously contain, by weight: 4 - from 90 to 99.98% of solvent - from 0.01 to 8% of surfactant - from 0.01 to 2% of carboxylic acid, the total of the amounts of the three constituents being 5 100%.
In these compositions, the chlorofluorohydrocarbon is advantageously 1,1,2-trichloro-1,2,2-trifluoroethane and the complementary solvent is advantageously an aliphatic hydrocarbon such as hexane, an aliphatic cut such 10 as white spirit or kerosene, a halogenated aliphatic hydrocarbon such as chloroform, methylene chloride, a dichloroethane or trichloroethane, 1 ,1 , 2 , 2-tetrachloroethane, 1,1,2,2-tetrachloro-1,2-difluoroethane, perchloroethylene, trichloroethylene, or an aromatic hydrocarbon such as xylene. 15 The various surfactants described in European Patent 83/400293.3 can be used. The products are preferably those which result from the reaction of a quaternary ammonium chloride of formula (I) in which R' denotes a methyl group and R denotes an alkyl group having from 12 20 to 18 carbon atoms, with a mixture of mono- and dialkylphosphoric acids of formula (II), in which the symbol R" denotes an alkyl radical having from 4 to 14 carbon atoms, this reaction being performed in the presence of a fluorinated amine of formula (III), in which 25 the symbol q is from 4 to 10, and R^ denote a hydrogen atom or a methyl, ethyl or hydroxy ethyl § radical, and X denotes a saturated or unsaturated bivalent radical which is wholly hydrocarbon or is hydrocarbon substituted by a fluorine atom or a radical consisting of one or more of the above bivalent radicals and a -SC^-* 5 -CONH- or -NH- group.
The preparation of the surfactant, preferably in the solvent medium of the composition according to the invention, is described in European Patent 83/400293.3.
Examples of acids which can be used include: 10 valeric, caproic, oenanthic, caprylic, pimelic, suberic, azelaic and sebacic acids; oleic, linoleic, undecylenic and ricinoleic acids; cyclohexanemonocarboxylic or trans-1,2- or -1,4-cyclohexanedicarboxylic acids; benzoic, ortho- or para-hydroxybenzoic, 2-amino-benzoic, 3-nitro-15 salicylic, 5-nitrosalicylic, ortho-toluic and cinnamic acids.
The water-removing composition according to the invention can be prepared by simple mixing of its constituents. It can also be produced by adding the carboxylic acid to a composition containing the solvent 20 and the surfactant, prepared separately or in the presence of all or part of the solvent. When the surfactant is prepared directly in the solvent, the composition can contain all or part of the fluorinated amine hydrochloride formed, and this product can be removed in different ways, 6 for example by dissolution in water during drying, or by filtration, advantageously performed from a concentrated composition. The choice of extraction method of this hydrochloride is linked to its solubility in the medium 5 as will be appreciated by those skilled in the art.
The compositions according to the invention make it possible to accomplish very effective drying, and more specifically to remove water from the surface of articles of various kinds. It is especially suitable for removing 10 water from metal articles, objects made of glass or refractory materials, precious stones or plastic objects. By means of these compositions, rapid removal or displacement of the water is observed; also there is a substantial increase in the rate of separation of the 15 aqueous and organic phases formed during the removal of the water, which constitutes an advantage when the compositions are used in installations provided for this purpose. Thus, the water, rapidly separated from the drying composition, may be discharged into the drain by 20 means of a suitable device (settler).
The Examples which follow further illustrate the present invention. In these examples, the abbreviations have the following significances: - chloride: dimethyldilaurylammonium chloride 7 (+) <-) (C -j 2 H25) 2 N ^CHj)2 CL The product used is commercially available, -containing 7 5% of active material in isopropanol 5 and 0.161 chlorine equivalent per 100 g. It is a mixture of homologues according to the following distribution (by weight): C8 3% C16 10% C -j Q 6% C-jg saturated 2% C-j 2 56% C1 g unsaturated 5% C14 18% - F 113 : 1,1,2-trichIoro-1,2,2-trifIuoroethane. Preparation and formulation The following mixture is prepared at room 15 t empera ture : . chloride: 8.32 g (0.88 mole) . ButyIphosph0ric acid: 2.69 g (1 mole) . Amine C^F-jjH^SC^NH C3H6 N (C H ^) 2 -7.82 g (1 mole) . F 113: 150 g The initial solution becomes turbid quite quickly, and after the mixture has been left to stand for 24 hours, 4.2 g of a white crystallised solid, identified as the fluorinated amine hydrochloride, are collected after 25 filtration.
The filtrate, which is completely clear, is diluted with F 113 (concentration 0.04% by weight). 8 This formulation, a control, is designated F ormulation 1.
Formulation 2 contains, by weight, 99.86% of F 113, 0.04% of filtrate of the Formulation 1 and 0.1% of caprylic acid.
Formulation 3 contains, by weight, 99.86% of F 113, 0.04% of the filtrate of the Formulation 1 and 0.1% of benzoic acid.
Exa mpl e 1 : emuLsification test 1.1. In a bottle, there are placed 50 g of the formulation to be tested and 18 g of distilled water. The bottle is shaken vigorously for 30 seconds. The emulsion formed is then allowed to stand, and the time, and the thickness of the interface between the organic lower phase and the aqueous upper phase, are measured.
The following observations are made: Thickness in mm of the interface Duration in mi nut es Formulation No. 1 Formulation No. 2 Formulation No. 3 3 1 0 0 60 0 0 0 The bottles containing the above formulations are again shaken for 30 seconds. 9 Thickness in mm of the interface i Duration j Formulation Formula t i on No. 2 Formulation No. 3 Mi n Hours No. 1 13 11 6 60 4 1 2 28 2 0 48 1 0 1.2. (Control). In a tank of approximate size 10 200 x 150 x 150 mm/ a mixture consisting of 7 I of the Formulation No. 1 and 0.800 I of distilled water is circulated with continuous recycling by means of a pump and at a flow rate of approximately 300 l/h.
After 5 mi n, it is observed that the mixture has 15 a homogeneous appearance. A sample withdrawn after this time shows, after 3 mi n, 2 phases: a slightly turbid lower organic phase and a viscous upper phase which is, in fact, an emulsion of the organic phase and the aqueous phase. The appearance of a cIear aqueous phase is not observed 20 after 48 hours.
. (Invention). The procedure described above is carried out using the Formulation No. 3. A sample is withdrawn after the mixture has been circulated at a flow rate of approximately 300 l/h for 5 minutes. The 1 o sample shows, after 2 minutes, an organic phase and a distinctly separate aqueous phase without a trace of emulsion.
Example 2: drying tests Drying of nickel 45 rpm record stampers.
A 45 rpm stamper is previously degreased in an alkaline detergent solution in the presence of ultrasound, and then rinsed in running tap water. It is then immersed in one of the Formulations 1, 2 or 3, brought to boiling for 3 minutes, and then rinsed in pure F 113.
Over 5 tests, it is observed that 100% drying of this stamper is obtained with each of the formulations used: the compositions according to the invention hence combine great drying efficiency with the improved rate of separation of the phases. 11
