Abstract
Emulsifying agents are obtained by treating ricinenic acid, its glyceride or amide at 80-100 DEG C. with salts of sulphurous acid. Instead of starting from pure materials, the product obtained by splitting off water from castor oil may be used directly or after saponification. In an example, ricinenic acid is dissolved in hot water by the addition of caustic soda, and the sulphonation effected by means of sodium bisulphite. Ricinenic acid amide may be similarly sulphonated. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the treatment with sulphurous acid or salts thereof of any fatty acid containing more than eight carbon atoms, or derivatives thereof, containing conjugated double bonds. The sulphonation of elaeostearic acid is mentioned. This subject-matter does not appear in the Specification as accepted.ALSO:Wetting and emulsifying agents are obtained by treating ricinenic acid, its glyceride or amide at 80-100 DEG C. with salts of sulphurous acid. Instead of starting from pure materials, the product obtained by splitting off water from castor oil may be used, directly or after saponification. To facilitate the sulphonation, the reacting materials may be emulsified. In an example, ricinenic acid is dissolved in hot water by the addition of caustic soda, and the sulphonation effected by means of sodium bisulphite. Ricinenic acid amide may be similarly sulphonated. Ricinenic acid amide is obtained by passing ammonia into the acid, and heating the resulting ammonium salt to remove water. The Specification as open to inspection under Sect. 91 (3)(a) comprises also the treatment with sulphurous acid or salts thereof, of any fatty acid containing more than eight carbon atoms, or derivatives thereof, containing conjugated double bonds. The sulphonation of elaeostearic acid is mentioned. This subject-matter does not appear in the Specification as accepted.
