摘要：NOVELTY - A loaded catalyst comprises titanium tetrachloride. USE - A catalyst used for esterification of carboxylic acid and alcohol (claimed). ADVANTAGE - The catalyst is inexpensive, and has high activity to substitute traditional inorganic strong acid catalyst and to simplify the post treatment process of the esterification. The catalyst is used in a reduced amount while keeping esterifying selectivity and product yield, is convenient to separate from the reaction product, and can be reused for many times. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for catalyzing esterification, comprising: (A) uniformly mixing titanium salt with carboxylic acid and alcohol; (B) heating and refluxing to esterification; (C) reacting for 0.5-24 hours; and (D) modifying for 0.5-5 hours.
