## Abstract The purity and reactivity of trimethylene carbonate (TMC, 1,3‐dioxan‐2‐one) depends largely on the purification procedure. Vacuum distillation and recrystallization from CCl~4~ are less efficient than recrystallization from tetrahydrofuran (THF) or ethyl acetate (EtAc). TMC recrystalliz

Cyclobis(diethy1ene glycol carbonate), (DEGC),, was synthesized by polycondensation of diethylene glycol with diethyl carbonate followed by thermal depolymerization of the crude polycarbonate in vacuo. BuSnCl,-initiated polymerizations of (DEGC)2 in chlorobenzene at 100 "C gave poor results. Therefo
