Abstract: 501,590. Wetting &c. agents; making emulsions. NAAMLOOZE VENNOOTSCHAP CHEMISCHE FABRIEK SERVO, and ROZENBROEK, M. D. Aug. 26, 1937, No. 23459. Convention date, Aug. 26, 1936. Samples furnished. [Classes 2 (iii) and 15 (ii)] [Also in Group III] Products useful in the textile, paper, leather and cosmetic industries as wetting, washing, emulsifying, cleansing, softening and foaming agents are obtained by sulphonating the esters prepared by esterifying 'one or more of the hydroxy groups of a polybasic boron or phosphorus-containing acid with a hydroxy compound of high molecular weight and esterifying one or more of the remaining hydroxy groups with a lower monohydric hydroxy compound. The hydroxy compounds of high molecular weight, which must contain more than eight carbon atoms include partial ethers of a higher alcohol with a lower polyhydric alcohol and also partial esters of a higher fatty acid with a lower polyhydric alcohol. The lower monohydric hydroxy compounds, which must contain six or less carbon atoms, include partial ethers of a lower monohydric alcohol with a lower polyhydric alcohol and also partial esters of a lower carboxylic acid with a lower polyhydric alcohol. Any free hydroxy groups present in the resulting boron and phosphoruscontaining esters may be esterified with lower polyhydric alcohols and the products may be re-esterified with the polybasic boron or phosphorus, containing acids. The esterification with the lower monohydric hydroxy compound may take place before, during or after the sulphonation. In examples, esters prepared as follows are sulphonated: (1) boric acid is esterified with lauryl alcohol and propanol-2 ; (2) phosphorustrichloride is treated with glycol monoether of octadecanol and then with butanol; (3) the boric acid ester of oleic acid monoglyceride is treated with pentanol ; (4) the boric acid ester of lauric acid monoglyceride is treated with butanol ; (5) the boric acid ester of oleic monoglyceride is treated with phosphorus trichloride arid then with butanol ; (6) boric acid is esterified with a mixture of higher alcohols and then with butanol; (7) elaidic acid monoglyceride is treated with boric acid and then with propanol-2; (8) glycol is esterified with coconut oil fatty acid and then with boric acid or phosphorus pentoxide and the resulting ester treated with dimethyl-2 : 3- butandiol-3:4 and propanol-2. In further examples, the boric acid ester of oleic acid monoglyceride is simultaneously sulphonated and esterified with propanol-2, and also esterified with butanol after sulphonation. Samples have been furnished under Sect. 2 (5) of products prepared by the sulphonation of the following esters : (1) cetylalcohol is esterified with boric acid and the product treated with phenol or diethylaminoethanol ; (2) cetyl alcohol is esterified with boric acid and the product treated with glycerol and acetylated; (3) naphthol is esterified with boric acid and then treated with butylalcohol; (4) naphthenic acid is esterified with glycerol and the product treated with boric acid and isopropyl alcohol; (5) octadecanolglycolether is treated with phosphorus trichloride and the product esterified with butylglycolether ; (6) the boric acid ester of lauric acid monoglyceride is esterified with monobutylglycolether; (7) boric acid is esterified with hydroxyquinoline and the product treated with isopropylalcohol ; (8) cetylalcohol is esterified with phosphoruspentoxide, and the product treated with phenol; (9) naphthenic acid monoglyceride is esterified with phosphoruspentoxide and the product treated with isopropylalcohol. Specification 452,508 is referred to.
