Process for the preparation of 1,3-cyclohexanedimethanol from isophthalic acid

Disclosed is a process for the preparation of 1,3-cyclohexanedimethanol from isophthalic acid. Isophthalic acid is esterified with (3-methylcyclohexyl)methanol and the isophthalate ester hydrogenated to 1,3-cyclohexanedimethanol in a 2-stage process. The (3-methylcyclohexyl)methanol that is formed d...

Zusammenfassung:	Disclosed is a process for the preparation of 1,3-cyclohexanedimethanol from isophthalic acid. Isophthalic acid is esterified with (3-methylcyclohexyl)methanol and the isophthalate ester hydrogenated to 1,3-cyclohexanedimethanol in a 2-stage process. The (3-methylcyclohexyl)methanol that is formed during the hydrogenation step is recycled to the esterification reaction. Also disclosed is a method for purifying and recovering the 1,3-cyclohexanedimethanol product.
