Abstract

551,246. Emulsifying agents. NATIONAL OIL PRODUCTS CO. March 21, 1941, No. 3871. Convention date, March 23, 1940. [Class 1 (i)] [Also in Group IV] Sulphonated products suitable as emulsifying agents are obtained by treating with an alkalibisulphite an ester of an aliphatic carboxylic acid containing at least three carboxylic groups two of which are attached to adjacent carbon atoms connected by a double bond and an alcohol having more than eight carbon atoms. Alternatively, the said polycarboxylic acid or partial ester thereof is first treated with the alkali-bisulphate and is then esterified with the alcohol or phenol. Esterification is facilitated by adding methyl alcohol or the usual esterification catalysts. Aconitic acid methylaconitic acid and esters of 1:1:2:3: 4-pentacarboxybutene-3 are mentioned as starting materials. For esterification undecyl and cetyl alcohols may be used as well as polyhydric alcohols. The sulphonated esters may be neutralised with alkali or organic amines such as triethanolamine. The Specification as open to inspection under Sect. 91 comprises also the sulphonation of esters of aliphatic carboxylic acids containing at least three carboxylic groups in general. Tricarballylic acid, 1:3:4-tricarboxybutine-1, #-carboxyadipic acid, α-methyl-#-carboxyglutaric acid, α or #-carboxypimelic acid, α : α-dimethyltricarballylic acid and 1 : 3 : 4 : 6-tetracarboxy hexane are mentioned. This subject-matter does not appear in the Specification as accepted.
