PROCEDURE FOR OBTAINING SALTS OF TRIETHANOLAMINE ESTERS FROM QUATERNIZED FATTY ACIDS OF COLOR AND STABLE ODOR.

摘要

THE INVENTION REFERS TO SALTS OF ESTER TRIETHANOLAMINE QUATERNARY FATTY ACID OF FORMULA (I) WHERE R {SUP, 1} CO IS AN ACIL GROUP WITH 6 TO 22 CARBON ATOMS; R {SUB, 2} AND R {SUB, 3}, INDEPENDENTLY FROM EACH OTHER, ARE HYDROGEN OR R {SUP, 1} CO; R {SUP, 4} IS AN ALKYL GROUP WITH 1 TO 4 CARBON ATOMS OR A GROUP (CH {SUB, 2} CH {SUB, 2} O) {SUB, Q} H; N, M AND P TOTAL TOGETHER ARE 0 OR A NUMBER FROM 1 TO 12; Q IS A NUMBER FROM 1 TO 12 AND X IS A HALOGENIDE, AN ALKYL SULPHATE OR ALKYL PHOSPHATE. SUCH SALTS EXHIBIT HIGH STABILITY OF COLOR AND ODOR, EVEN IN STORAGE FOR LONG PERIODS, AND MAY BE OBTAINED BY (A) ESTERIFICATION OF FATTY ACIDS WITH TRIETHANOLAMINE IN THE PRESENCE OF HYPOPHOSPHOROUS ACID, (B) PEROXIDE AND ALKALINE METAL BORATES AND (C) PERFORMANCE OF THE QUATERNIZATION IN THE PRESENCE OF PHENOL DERIVATIVES AND HYDROXYCARBOXYLIC ACIDS AS STABILIZERS.
