摘要:
A method for producing a phenolphthalein compound is disclosed, comprising: reacting a phenolic compound of the formula: wherein Ra is a hydrogen or a C1-C12 hydrocarbyl group, with a phthalic anhydride compound of the formula: wherein Rb is a hydrogen, a C1-C12 hydrocarbyl group, or a halogen, in the presence of an ionic liquid catalyst composition and a promoter to form a reaction mixture comprising a phenolphthalein compound of the formula: wherein each Ra is independently a hydrogen or a C1-C12 hydrocarbyl group, and Rb is a hydrogen, a C1-C12 hydrocarbyl group, or a halogen; wherein the ionic liquid catalyst composition comprises a combination of an ionic liquid and a metal halide wherein the metal is selected from the group consisting of a Group IIB, IIIA, VIII, or IVA metal, and a combination thereof.
