"ESTERS OF FATTY ACIDS AND YOUNG ALCOHOLS, AND METHOD FOR THE PREPARATION AND USE OF THE SAME". esters derived from fatty acids and juvenile alcohols of the general formula I where X means the oxygen atom or the NH group, Y means the NH group or the oxygen atom, R means methyl, ethyl, 1-propyl, 2-methylethyl or propargyl and R 'means saturated or unsaturated alkyl with 4 to 22 carbon atoms. esters derived from fatty acids and juvenile alcohols are prepared by a reaction of a juvenile alcohol of the general formula II where X means the oxygen atom or the NH group, Y means the NH group or the oxygen atom and R means methyl, ethyl, 1-propyl, 2-methylethyl or propargyl with a fatty acid chloride of the general formula III R'COCI (III) where R 'means saturated or unsaturated alkyl with 4 to 22 carbon atoms, with continuous agitation, at O - 70 <198> C, using a convenient solvent, such as toluene, xylene or benzene, and in the presence of a basic catalyst, such as triethylamine, pyridine or quinoline. The compounds of the general formula I according to claim 1 are applied for the control of insect population density. |
