Procedure

A 1-liter separable flask fitted with a stirrer, thermometer and condenser provided with a calcium chloride desiccator was charged with 90.1g (1 mol) of 1,4-butanediol and 332g (2 mols) of methyltetrahydrophthalic anhydride. Reaction was conducted 2 hours at 160° to 180° C, providing 420g of 2:1 adduct of methyltetrahydrophthalic acid 1,4-butanediol having an acid value of 259.3.
