Patent GB-741770-A (GB)
Title: A process for the manufacture of sulphonated fatty acid nitriles
IPC: C07C309/03
Filed: 1953-10-13
Abstract: A process for the manufacture of sulphonated fatty acid nitriles comprises sulphonating a nitrile of a saturated water-insoluble fatty acid with sulphur trioxide, either in free form or in the form of an addition product with an ether.  The chief nitriles are those having 8 to 25 carbon atoms and may be obtained by the reaction of the free fatty acids with ammonia at elevated temperatures.  The sulphur trioxide addition products may be those formed with, for example, diethylether, dipropyl ether, mixed ethers, halogen-containing ethers such as dichlorodiethyl ether and cyclic ethers such as dioxane.  The sulphur trioxide itself can be introduced into the nitrile together with an inert gas such as carbon dioxide, nitrogen or air.  The reaction takes place at temperatures as low as -30 DEG  C. when sulphur trioxide is used, but preferred reaction temperatures are -20 DEG  to + 40 DEG  C. The temperature may be controlled by allowing evaporation of solvents and diluents present in the reaction mixture, such as sulphur dioxide, carbon disulphide, ethylene dichloride, perchlorethylene and other chlorinated, fluorinated and mixedly halogenated hydrocarbons.  The product can be neutralized, preferably after the removal of solvents and ethers, by the addition of caustic soda solution, potash, ammonia, triethanolamine or other organic bases.  The products are foaming, moistening and dispersing agents and can be used as washing and cleansing agents and in the treatment of metals and textiles.  In examples lauric acid nitrile is sulphonated by reaction with (1) sulphur trioxide at 5 DEG  C. in nitrogen or carbon dioxide, excess nitrile being removed; (2) sulphur trioxide in liquid sulphur dioxide; (5) a product obtained by mixing sulphur trioxide with dichlorethyl ether and ethylene dichloride, the reaction mixture being heated at 80 DEG  C.; (6) a product obtained by mixing dioxane, ethylene dichloride and sulphur trioxide at 0 DEG C., the sulphonation reaction mixture being heated at 80 DEG  to 90 DEG  C.  In further examples (3) coconut fatty acid nitrile is sulphonated with sulphur trioxide in ethylene dichloride at up to 50 DEG  C.; (4) palmitic acid nitrile is sulphonated with sulphur trioxide in perchlorethylene.  The products are neutralized with dilute caustic soda solution.
