Ti -- (62) P (Ti as acetyl triisopropyl titanate) -- Acetyl triisopropyl titanate [CH3COO-Ti(OCH(CH3)2)3, M.W. 284] was prepared by adding slowly with stirring and cooling and under a dry atmosphere glacial acetic acid (CH3COOH, M.W. 60) to titanium tetraisopropoxide in an amount to provide a 1/1 molar ratio of acetic acid/titanium tetraisopropoxide. (The isopropyl alcohol thus displaced by the acetic acid was not removed.) This catalyst may be added to the ester interchange reaction mixture undiluted or as a solution in any of a number of suitable solvents such as n-butyl alcohol, methyl alcohol, ethylne glycol, etc.
