Propylene carbonate boiling points

Two compounds are included in tins category of antimicrobials. One is tile gas, ethylene oxide, the other, propylene oxide. a colorless liquid with a boiling point of 35 0 Ethylene is highly reactive and must be used carefully and only with proper equipment. Somewhat less hazardous from an explosion standpoint, propylene oxide also has an explosive range of 2-22%. Consequently, these materials are usually mixed with inert substances, such as carbon dioxide or organic diluents. 

Although thermal degradation of PHB in air or a nitrogen atmosphere has been well studied (69), there are few examples which show that PHB degrades in organic solvents. The molecular weight is known to decrease in propylene carbonate and ethylene carbonate at 110-140°C (67), in chloroform-methanol mixtures at room temperature (70), and in methylene chloride, chloroform, and 1,2-dichloroethane at their boiling points (68).
