Synthesis of bleach activators

摘要

The synthesis of phenol sulfonate esters of alkanoyl amino acids is conducted in the presence of aqueous base to provide bleach activator compounds. Thus, the acid chloride of N-nonanoyl-6-aminocaproic acid is reacted with the sodium salt of p-phenol sulfonate in the presence of water at a pH in the range of about 9 to about 12 to yield the corresponding phenol sulfonate ester. The synthesis of the phenol sulfonate ester of the monononyl amide of adipic acid is also illustrated.
