Procedure

A reactor was charged with 633.0 g of 3,5,5-trimethylhexanoic acid (4.00 mol, manufactured by KH Neochem Co., Ltd.) and 817.5 g of acetic anhydride (8.00 mol, manufactured by Wako Pure Chemical Industries, Ltd.), and the resulting mixture was stirred for 1 hour at 120° C. After completing the reaction, the reaction product was distilled at 157° C. to 162° C. under the reduced pressure of 0.4 kPa, to thereby yield 496.4 g of 3,5,5-trimethylhexanoic anhydride.
