Reaction Steps
155 parts by mass of the caproic acid and an equivalent amount of N-chlorodiisopropylamine were added to 1,000 parts by mass of 84% sulfuric acid and were reacted for 5 hours at 25° C. to obtain 187 parts by mass of 5-chlorocaproic acid. 187 parts by mass of the 5-chlorocaproic acid were boiled with an aqueous solution of an equivalent amount of sodium hydroxide to obtain 136 parts by mass of δ-caprolactone.
