Abstract
Alkyl titanates are made by forming a titanium tetrachloride alkanol mixture wherein the alkanol contains from 2 to 5 carbon atoms, but excluding tertiary butyl alcohol, and the titanium tetrachloride/alkanol molar ratio is at least 1 to 2 and below 1 to 4; physically removing hydrogen chloride from the reaction mixture; adding alkanol to give a titanium tetrachloride/alkanol ratio of at least 1 to 4; adding a base to the reaction mixture, which base will not form water with the hydrogen chloride liberated, and thereafter recovering the alkyl titanate. The preferred tetrachloride to alkanol molar ratio is initially in the range of 1:2 to 1:3 and particularly 1:2.5. The most preferred alkanols are isopropanol or normal butyl alcohol. The reaction may be carried in an inert solvent amongst which are specified hydrocarbons or chlorinated hydrocarbons, such as heptane, hexane, toluene, benzene, petroleum ether, cyclohexane, carbon tetrchloride or chloroform. The preferred method of hydrogen chloride removal is by boiling the reaction mixture or by subjecting it to reduced pressure. Bases specified as suitable are gaseous ammonia and pyridine. Bases forming hydrochlorides which are substantially insoluble in the reaction mixture are preferred. The hydrochloride thus formed may be first separated from the reaction mixture after which the alkyl titanate may be separated from any excess alkanol and/or inert solvent by distillation. The examples describe the preparation of isopropyl titanate and n-butyl titanate using as base ammoniagas. Comparative data is also included on the amount of hydrogen chloride retained after mixing titanium tetrachloride and alkanol in various molar proportions and after boiling such mixtures and after subjecting them to reduced pressure.
