Esterification reaction

摘要

Process of producing relatively pure esters, which comprises reacting a solution of organic acid compound in excess monohydroxy compound in the presence of a tetraalkyl titanate esterification catalyst to produce a monohydroxy solution of organic ester, treating the dissolved organic ester in the substantial absence of water at a temperature of at least 120 DEG C. with solid alkaline earth metal oxide or hydroxide adding at least two mols of water per mol of alkaline earth metal at up to 100 DEG C. and partitioning solid alkaline earth metal compound from the dissolved organic ester.
