Disclosed is a process for recovering formic acid from a formate ester that allows for recovery of a formic acid product comprising greater than 75 wt. % formic acid. Disclosed is also a process for producing formic acid by carbonylating a carrier alcohol, hydrolyzing the formate ester of the carrier alcohol, and recovering a formic acid product comprising greater than 70 wt. % formic acid. Discloses are carrier alcohols that enable more favorable hydrolysis equilibriums and/or distillation sequences.

Process for making formic acid utilizing higher-boiling formate esters

Disclosed is a process for the preparation of a terephthalic acid di-ester by the esterification of terephthalic acid with an alcohol at elevated and normal temperature and pressure while the water of the reaction is removed from the reaction mixture via an inert gas or a column.

Production of terephthalic acid di-esters

Disclosed is a process for the preparation of di-n-butyl terephthalate by the esterification of terephthalic acid with n-butanol in the presence of a strong acid while employing a fractionating column.
