AROMATIC ALCOHOL P-STYRENESULFONIC ACID ESTER

NEW MATERIAL:An aromatic alcohol p-styrenesulfonic acid ester. EXAMPLE:Citronellyl p-styrenesulfonate. USE:An aromatic alcohol releasing agent, keeping aroma for a long period. PREPARATION:An aromatic alcohol is reacted with p-styrenesulfonyl chloride to give the titled compound. A terpene alcohol such as citronellol, l-menthol, borneol, etc., an aromatic ring-containing alcohol such as eugenol, p-anisyl alcohol, cinnamyl alcohol, etc., may be cited as the aromatic alcohol. The copolymer of this compound can change the degree of hydrophilic nature depending upon a monomer to be copolymerized, and regulate a hydrolysis rate, so strength of aroma and durability can be controlled.
