Process for the preparation of a capillary active agent. The main patent No. 190153 relates to a process for the production of a capillary active agent, which is characterized in that a mixture of alkyl cresols is obtained by condensation of synthetic olefin-rich gasoline with technical cresol containing mainly orthocresol in the presence of condensing agents,
perhydrogenated in the presence of hydrogenation catalysts and the hydrogenation product obtained is converted into water-soluble form by treatment with sulfonating agents.
The present invention relates to a process for the preparation of a capillary active agent, which is characterized in that a mixture of alkylated a-naphthols, which is obtained by condensation of a-naphthol with an olefin-rich hydrocarbon mixture in the presence of condensation agents, under Ver use of hydrogenation catalysts and,
the hydrogenation product obtained is converted into water-soluble form by treatment with sulfonating agents.
The hydrogenation can bezw according to known Me methods using catalysts such as nickel, copper, 'cobalt, chromium, zinc, cadmium, manganese or noble metals. made of these metals mixed catalysts; furthermore, also Ka catalysts, which are insensitive to a sulfur content, such as molybdenum, tungsten and the like, can be used.
The sulfonation can be carried out with the usual sulfonating agents, such as conc. Sulfuric acid, sulfuric acid, SO3, chlorosulfonic acid or addition products of SO3 with tertiary bases and the like, it being possible to work in the presence or absence of dehydrating agents, and also solvents or diluents.
It is expedient to convert the acidic sulfonation product into salts for its practical use, preferably the alkali metal salts, as well as the ammonium salts or their organic substitution products. <I> example:
154 parts by weight of a-naphthol, 3.25 parts by weight of synthetic gasoline containing about 33% olefins and up to about 22.0 parts by weight, 5 parts by weight of technical-grade perchloric acid (about 50% HC104) 70 to <B> 80 '</B> and reacted with intensive stirring at 90 to <B> 100' </B>.
The resulting mixture of alkylated α-naphthols is isolated from the reaction mixture by fractional distillation and treated with 10 percent by weight of an active hydrogenation catalyst at 200 to 210 <B> '</B> and increased hydrogen pressure (100 to 150 atmospheres)
hydrogenated. 2-60 parts by weight of the hydrogenation product separated from the catalyst are slowly added to a mixture of 200 parts by weight of dibutyl ether and 135 parts by weight of chlorosulfonic acid with stirring at -10 to -5 and, after the addition, for some time at -5 to -I- 10 '</B> mixed together.
When the reaction has ended, the mixture is neutralized with a mixture of aqueous sodium hydroxide solution (25% NaOH) and crushed ice, with good cooling. After the di-butyl ether has been separated off and the aqueous solution obtained has been worked up, a mixture of the sodium salts of the hydrogenated and sulfonated alkylated α-naphthols is obtained in the form of a white water-soluble powder.
The new capillary-active agent can be used in particular in the form of its water-soluble sodium salt wherever the capillary-active properties of liquids, especially aqueous solutions or emulsions, are to be increased.
For example, the new capillary active agent for foam generation, emulsifying, dispersing, wetting, impregnating, peptizing, stabilizing, leveling, distributing, dissolving and the like can be used. Use in a wide variety of industries.
For example, it can be used in a wide variety of processes and finishing methods in the textile industry, as a soap substitute, as an auxiliary in the leather or fur industry, and for washing and cleaning textiles, linen and the like. It can also be mixed with other known capillary-active substances, as well as with cleaning agents, etc.
They are used, for example, mixed with salts such as alkali carbonates, trisodium phosphate and other alkali orthophosphates, alkali pyro- and metaphosphates, poly- and hypophosphates, and also with water glass, alkali metasilicates or alkali borates. A combination of the new capillary-active substance with agents is also advantageous
such as sodium sulfate, sodium naphthalenesulfonate, and the like. a., as well as with oxygen-releasing compounds, such as peroxides, perborates, “persulfates.
The new capillary-active agent can also be used in a mixture with solvents such as organic hydrocarbons, alcohols and the like, or in a mixture with superfatting agents, other enzymes such as urease or pancreatic reactin, or as a component of cleaning or abrasive agents.
Also in a mixture with disinfectant phenols such. B. with p-chloro-metacresol, the new capillary-active agent can be used advantageously.
