KINETICS OF ESTERIFICATION OF MONOISOPROPYLPHENOLS WITH PHOSPHORYL TRICHLORIDE

The kinetics of liquid-phase isothermal esterification of POCl3 with 2-isopropylphenol and 4-isopropylphenol have been studied within the temperature intervals of 110 to 130 and 90 to 110 deg C, respectively.The rate constants and activation energies of the individual steps of this three-step reaction have been calculated from the values measured.The reaction rates of the two isomers markedly differ: at 110 deg C 4-isopropylphenol reacts faster by the factors of about 7 and 20 for k1 and k3 respectively.This finding can be utilized in preparation of mixed triarylphosphates, since the alkylation mixture after reaction of phenol with propene contains an excess of 2-isopropylphenol over 4-isopropylphenol.
