Definitions

  • the present invention relates to the use of polyisobutene and polyisobutene derivatives as a substitute for raw and / or purified, optionally chemically modified wool fat and wool fat mixtures in fatliquoring agents for leather production, preparations, in particular fatliquoring agents, containing polyisobutene and their use in leather production, and a method for the production of these preparations and the leathers produced using these preparations.
  • fatliquoring agents serve to make skins and pre-tanned leather supple, to increase their fullness and strength and to protect them from moisture, dirt and chemical influences from outside (see H. Herfeld, "Library of Leather", Vol. 4 , (1985), p. 13 ff., P. 59 ff. Frankfurt am Main: Umschau Verlag 1987)). They should cover the individual skin fibers with a thin film of fat to isolate them from each other and keep them movable, but on the other hand they should not completely fill the spaces between the fibers, otherwise the porosity and the breathability of the leather will be impaired.
  • greasing agents generally consist of greasing substances, such as native fats, fatty oils, waxes, resins and their derivatives and / or petroleum fractions and their derivatives, and waxy products such as "wool fat", in raw, cleaned and / or prepared (lanolin)
  • the fatty substances can, if desired, be chemically modified, ie they can be in a modified chemical structure.
  • the aim of these chemical modifications is to optimally adapt the application-related properties of the greasing substances, such as, for example, hydrophilicity, hydrophobicity, solubility, dispersibility, penetration and anchoring properties, special uses or the requirements of the users.
  • wool fat In its raw and / or chemically modified form, but especially in its cleaned or prepared forms (lanolin), wool fat is of great importance in the field of leather production. There wool fat, in particular lanolin, is used as neutral fat. A certain hydrophobic effect is added to the greasing and filling effect.
  • Wool fat in terms of its composition more appropriately referred to as wool wax, is a fat-like secretion from the sebum glands of sheep, which is found in their
  • Wool settles and is obtained from it through complex and therefore expensive cleaning processes.
  • Raw wool fat lanolin
  • lanolin is a greasy, foul-smelling, yellow-brown
  • a total of over 30 different fatty acids and aliphatic triterpenoid and steroid alcohols have been identified in wool fat.
  • the malodorous and coloring components of the raw wool fat are largely destroyed by oxidation.
  • the pure water-free wool fat (wool wax) obtained in this way is a light yellow, translucent mass, with a weak, pleasant smell with a density
  • lanolin is a mixture which is made by melting together about 65 parts of wool fat, about 20 parts of water and about 15 Parts of viscous paraffin.
  • neutral wool wax or "lanolin”
  • purified and highly purified wool grease is used in cosmetics in creams, in toilet soaps it serves as a superfatting agent, in pharmacy it is used e.g. used in the manufacture of plasters, ointments and suppositories and in tablet pressing it can serve as a release agent.
  • High quality lanolin as used in the cosmetic and medical industry, has a market price of approx. 8-10 DM / kg. Less pure, "inferior” lanolin is incorporated into fatliquors as a neutral fatlip component.
  • lanolin has a number of disadvantages. Since lanolin is native, you always have to expect fluctuating composition, purity, and quality, as well as seasonal price fluctuations. For the manufacturers of lanolin-containing products, this means permanent optimization and revision of the setting of their products in order to be able to manufacture products with consistent quality. Last but not least, due to the increasing demand for high-quality lanolin, the available quantities of inferior lanolin decrease, which has led to an extreme price increase of the latter (from approx. 2 DM / kg to 6-8 DM / kg).
  • An object of the present invention was to provide a synthetic compound
  • An object of this invention are thus fatliquors for the fatliquoring of skins and for the production of leather, comprising neutral and / or optionally chemically modified native fatliquoring components, and one or more emulsifiers, which are characterized in that the lipidifying components are polyisobutene and / or

  • R has one of the meanings given for R, with the exception of hydrogen, where the two R 3 radicals can be the same or different,
  • R 4 and R 5 may be the same or different and represent hydrogen, hydroxy, lower alkoxy, poly-lower alkoxy or one of the radicals R 4 or R 5 represents hydrogen and the other represents a sulfato group (- OSO 3 H), a sulfone group (-SO 3 H), an amino, alkylamino or dialkylamino group with a total of 1 to 6, preferably 2 to 4, C atoms in the alkylamino or dialkylamino groups, or for groups of the formula -O (C p H 2p ) COOH, where p is an integer from 1 to 7, preferably 1 to 3, or their salts or their lower alkyl esters having 1 to 5, preferably 1 to 3, C atoms in the lower alkyl radical.

B. nitriles, amides and especially esters or anhydrides, with alkyl (1) and alkyl (2) radicals are particularly preferred in which the said substituents are bonded to the alkyl radical in the 1- or 2-position are.
  • substituted alkyl groups which can represent R 2 or R 3 are:
  • Polyisobutene itself is produced on a large industrial scale in various types, which differ in their molecular weight, and is marketed under various names, for example as ® Oppanole and ® Glissopale. They are usually produced by polymerizing isobutene in the presence of Friedel-Crafts catalysts such as boron trifluoride or aluminum chloride.
  • Polyisobutene derivatives of the formula I which contain carboxyl groups or their functional derivatives in radicals R 2 and / or R 3 are expediently prepared from polyisobutene by an ene reaction, ie by reaction of polyisobutene of the desired molecular weight or of compounds of the formula I in which R 1 is a radical of formula II with enophiles containing the desired substituents.
