Patent ID: 8853433

Claim:
A process for the preparation of C 8 -C 22 acyl amido compounds which comprises: (i) reacting an amino compound or salt thereof having a structure (I), wherein R 2 is hydrogen, CH 2 COOX or a C 1 -C 5 alkyl radical; R 3 is hydrogen; R 4 is selected from the group consisting of (CH 2 ) m CO 2 X, (CH 2 ) m SO 3 X, CH 2 NR 2 (CH 2 ) m OH and glucosyl radicals; R 5 is selected from the group consisting of hydrogen, hydroxyphenyl, C 1 -C 6 hydroxyalkyl, C 1 -C 10 alkyl, benzyl, hydroxybenzyl, alkylcarbamido, thioalkyl, and carboxylic radicals; X is selected from hydrogen, metal ions, amine salts and C 1 -C 4 alkyl radicals; and m ranges from 0 to 6; with a fatty acid ester in a medium comprising: a) a polyol of molecular weight ranging from 76 to 300; b) 0 to 10% by wt. water; and c) a basic salt containing catalyst selected from the group consisting of alkaline earth comprising metal containing hydroxides, phosphates, sulphates and oxides; (ii) heating reactants from step (i) to form the C 8 -C 22 acyl amido compounds having a structure (II) wherein R is a C 7 -C 21 saturated or unsaturated alkyl radical provided by the fatty acid ester; and the resultant mass has a Hunter Lab Color Scale value L ranging from 70 to 100; and iii) recovering a resultant mass from the process: wherein said fatty acid ester is a glyceride ester selected from the group consisting of monoglyceride ester, diglyceride ester and triglyceride ester, which triglyceride ester is selected from the group consisting of coconut oil, corn oil, palm kernel oil, palm oil, soybean oil, cottonseed oil, rapeseed oil, canola oil, sunflowerseed oil, sesame oil, rice oil, olive oil, tallow, castor oil and mixtures thereof.
