Patent ID: 8657943

Claim:
A process for the production of a biocidal compound, comprising the step of reacting a compound of formula (II) wherein: R1 is an O-acyl group containing from 18 to 22 carbon atoms, comprising from 0 to 3 unsaturations; R2 is an O-acyl group containing from 18 to 22 carbon atoms, comprising from 0 to 3 unsaturations; R3 is OH or O − ; R4 is [N + (CH 3 ) 3 ] or [N + H(CH 3 ) 2 ], with sodium methoxide generated in situ by the reaction of methanol with metallic sodium in a reflux condenser with cold water, coupled with an agitator; and the reaction lasts for about 50-90 hours at a temperature of about 45-60° C.
