Title: Preparation of plasticizer
Inventor: SAGARA FUMIO
IPC: C07C69/76
Filed: 1977-11-30
Abstract: PURPOSE:To obtain an ester plasticizer having improved storage stability, with a low titanium content, preparable while discharging only a small amount of waste water, by reacting a carboxylic acid with an alcohol in the presence of a tetraalkyl titanate as a catalyst, followed by treating the ester thus formed under specific conditions. CONSTITUTION:A carboxylic acid, e.g. phthalic anhydride, etc. is reacted with a 4-18C alcohol, e.g. 2-ethylhexanol, etc. in the presence of a verny small amount of a tetraalkyl titanate or its polymer in an atmosphere of an inert gas at 150-250 deg.C to remove the water formed as a by-product from the system. The acid value is reduced to 0.1 or below after 3-6 hr to distill away the excess alcohol, and the  formed ester is treated with a powdery solid alkali and an adsorbent in the absence  of water to give an ester plasticizer, e.g. 2-ethylhexyl phthalate, etc. EFFECT:Rinsing and steaming processes are unnecessary. Thermal energy, e.g. water, electric power, etc. can be reduced.
