Description
Изобретение относитс к способу получени производных сульфокарбоиовых кислот, представл юш ,их интерес в качестве полунродуктов в синтезе поверхностно-активных веществ.This invention relates to a process for the preparation of sulfo-carboxylic acid derivatives, represented by their interests, as semi-products in the synthesis of surfactants.
Известно, что при совместном действии сернистого ангидрида, хлора и облучени ультрафиолетовым светом алифатические углеводороды превращаютс в сульфохлориды согласно уравнениюIt is known that by the combined action of sulfur dioxide, chlorine and ultraviolet irradiation, aliphatic hydrocarbons are converted to sulfochlorides according to the equation

Получение монохлорангидридов сульфокарбоновых кислот путем фотохимического сульфохлорироваин карбоновых кислот жирного р да или их эфиров в литературе ие описано.The preparation of monochloroanhydrides of sulfo carboxylic acids by means of photochemical sulfochlorovirin carboxylic acids of the fatty series or their esters has been described in the literature.
Предлагаетс способ получени монохлорапгидридов сульфокарбоновых кислот, заключающийс в том, что кислоту жирного р да или ее эфир подвергают обработке смесью хлора и двуокиси серы при облучении ультрафиолетовым светом.A method for the preparation of sulfo carboxylic acid monochlorine hydrides is proposed.
Исходным сырьем дл получени монохлорангидридов вл ютс натуральные и синтетические (полученные окислением парафина) жирные кислоты или их зфиры в виде фракпи и или индивидуальиые с количеством атомов углерода от 3 по 30. В качестве источникаThe feedstock for the production of monochlorine hydrides are natural and synthetic (obtained by the oxidation of paraffin) fatty acids or their fractions in the form of fracpy and or individual with carbon numbers from 3 to 30.
света примен ютс ламны ртутпо-кварцевые высокого давлени (типа ПРК).Lights are applied to luminaires of high-pressure quartz-quartz (like PSC).
Предлагаемый метод позвол ет получать светлые продукты (мопохлорангидриды сульфокарбоновых кислот), которые благодар высокой реакпионной снособности хлорангидрндной грунпы легко могут быть превращены в различные поверхностно-активные вещества (ПАВ).The proposed method makes it possible to obtain light products (mopochloranhydrides of sulfo carboxylic acids), which, thanks to the high reactive ability of acid chloride soil, can easily be converted into various surfactants.
Сульфохлориды кислот и их поверхностноактивные производные имеют белый цвет, прп получении всеми ранее известными методами сульфокарбоновые кислоты приходитс осветл ть .Sulfur chlorides of acids and their surface active derivatives are white in color, and sulfo carboxylic acids, obtained by all previously known methods, must be clarified.
В св зи с этим представл ет интерес синтез ПАВ, которые имеют высокие поверхностноактивные и моющие свойства и могут использоватьс как самосто тельна основа дл синтетических моющих средств (CMC), так и вIn this connection, it is of interest to synthesize surfactants, which have high surface active and detergent properties and can be used as an independent basis for synthetic detergents (CMC), and in
качестве смачивателей, эмульгаторов и диспергирующих агентов. Эти ПАВ устойчивы в кислых средах, в морской и жесткой воде.as wetting agents, emulsifiers and dispersing agents. These surfactants are stable in acidic environments, in sea and hard water.
Реакцию фотохимического сульфохлорировани кислот провод т как в растворителеThe reaction of photochemical sulfochlorination of acids is carried out as in a solvent.
(четыреххлористый углерод или хлороформ), так и в расплаве.(carbon tetrachloride or chloroform), and in the melt.
