Abstract

Diesters of phthalic acid are prepared by a continuous process in which liquid phthalic anhydride is first mixed with alcohol in the molar ratio 1:0.8 to 1:1.2, the alcohol having a b.p. 180-250 DEG C. and having been preheated to 3-30 DEG C. below its b.p., the (mainly) monoester so formed is then mixed with excess alcohol, and the mixture heated until formation of the diester is practically complete. In examples, the alcohols used are 2-ethylhexanol, mixed iso-octanols (b.p. 184-189 DEG C.), isononanol and isodecanol (b.p. 212-215 DEG C.).
