| titleOfInvention | Esterification of ª,ª-unsaturated carboxylic acids with alkylene oxides |
| abstract | Hydroxy esters of the general formula <FORM:0997959/C2/1> wherein R is hydrogen or alkyl, R1 is hydrogen or alkyl and R11 is hydrogen, alkyl or chloromethyl are made by reacting, preferably at 70 DEG to 120 DEG C., and with advantage in the presence of a solvent, the carboxylic acid of the general formula <FORM:0997959/C2/2> especially acrylic, methacrylic or crotonic, with an alkylene oxide of the general formula <FORM:0997959/C2/3> especially 1,2-propylene oxide, 1,2-butylene oxide or epichlorohydrin, in the presence of, as esterification catalyst, a carboxylic amide, a urea, or a lactam or amide of a heterocyclic base. Named catalysts are N-methyl formamide, dimethyl formamide, dibutyl formamide, dimethylacetamide, N,N1 - dimethyl urea, N - formyl pyrrolidine, N-formyl morpholine, N-formyl piperazine, pyrrolidone, e -caprolactam. In the examples the following are prepared using as catalyst: glycol monoacrylate (dimethyl formamide = D.M.F.), 2-hydroxypropyl acrylate (D.M.F.), 3 - chloro - 2 - hydroxy - propyl acrylate (D.M.F.) and (formamide), 2-hydroxypropyl crotonate (D.M.F.), 2-hydroxypropyl methacrylate (dimethyl acetamide), 2-hydroxypropyl acrylate (dimethyl acetamide). |
