PRESSURE EFFECTS ON THE HYDROLYSIS OF 3-NITRO-4-ACYLOXYBENZOIC ACIDS CATALYZED BY HEXADECYLTRIMETHYLAMMONIUM BROMIDE MICELLE.

Article abstract of DOI:10.1246/bcsj.56.1341

The hydrolysis rate of anionic esters of 3-nitro-4-acyloxybenzoic acids catalyzed by a cationic HTAB micelle was measured at the pressures up to 2 kbar at 25 C to obtain the pressure dependences of the substrate bindings and the micelle-catalyzed hydrolysis. The reaction mechanism is discussed in terms of the volume change for the formation of the micelle-ester complex and the activation volumes for the hydrolyis catalyzed by micelle.
