Procedure

A single stage transesterification of propylene carbonate and methanol to form dimethyl carbonate and propylene glycol was conducted in a manner similar to that set forth in Example 1. The single stage experiment was conducted by combining a stream containing 61.25 weight percent of propylene carbonate and 38.76 weight percent of methanol with the potassium carbonate catalyst in a glass reaction tube. The results of the single stage transesterification of propylene carbonate and methanol are presented in Table 1.
