Abstract:
1. A method for producing an ester compound having non-heterocyclic groups, which comprises: subjecting a carboxylic acid and an alcohol to a dehydration-condensation reaction with adding no solvent or adding a nonaqueous solvent into a reaction system, in a presence of an involatile acid catalyst; then removing a residue of the acid catalyst without adding any solvent or in a nonaqueous solvent by bringing a weak basic substance into contact with the residual acid catalyst, forming a salt of the weak basic substance and the acid catalyst, and then filtering off the salt, wherein the alcohol is represented by formula (9): wherein T the carboxylic acid is represented by formula (2): wherein R wherein the substituent of the alkyl group or the alkenyl group is selected from the group consisting of a halogen atom, a haloalkyl group, alkoxy group, a haloalkoxy group, a thioalkoxy group, an acyl group, a substituted amino group, a carboxyl group, a cyano group, a nitrile group, and a nitro group, and the substituent of the aryl group or the aralkyl group is selected from the group consisting of a halogen atom, an alkyl group, a haloalkyl group, an alkenyl group, an alkoxy group, a haloalkoxy group, a thioalkoxy group, an acyl group, a substituted amino group, a hydroxyl group, a cyano group, a carboxyl group, a nitrile group, and a nitro group, and the ester compound obtained from the above alcohol of the formula (9) is a compound represented by a formula (10): wherein R
