Abstract Alkaline hydrolysis rate constants were measured for dimethyl, diethyl, di-n-butyl, di-iso-butyl, and di-(2-ethylhexyl) phthalate esters in water. A linear free energy relationship (LFER) was established for estimating alkaline hydrolysis rate constants for other phthalate esters. Dimethyl phthalate hydrolyzes to phthalic acid with the nono ester as an intermediate. The rate ratio for the second-order alkaline hydrolysis rate constants of the diester to the monoester is 12. Water solubilities for dimethyl, diethyl, di-n-butyl, and di-n-octyl and di-(2-ethylhexyl) phthalate esters were measured and compared with literature values.
