반응 단계
360 parts of methyl p-hydroxyphenylpropionate was reacted with 300 parts of hydroxystearic acid in the presence of 3 parts of dibutyl tin oxide at 150°C. in a nitrogen current for 10 hours. After completion of the reaction, the unreacted excessive methyl p-hydroxyphenylphropionate was distilled at 150°C. under reduced pressure to obtain crude p-hydroxyphenylpropyloxystearic acid. Recrystallization of this crude product from a mixed solvent of methylethylketone and n-hexane gave 350 parts of p-hydroxyphenylpropyloxystearic acid.
