Participants

Reaction Steps

A mixture of 41.7 g of 2,2,2',2',6,6,6',6'-octamethyl-4,4'-bipiperidylidene, 100g of ethylene oxide, 700 ml of ethanol and 0.06 g of concentrated hydrochloric acid was stirred at 105°-110° C for 10 hours in an autoclave. After completion of the reaction, the reaction mixture was concentrated, and the resulting residue was recrystallized from benzene, to give 37.2 g of the desired product as white crystals melting at 226.5°-227.5° C.
