Procedure

Thallic oxide was again prepared as in Example 1. 4.0 g of thallic oxide (8.8 mmoles), 30 g water (1.7 moles), 80 g propylene (1.9 moles) and 95 g carbon dioxide (2.2 moles) were added to the autoclave in Example 1 which was then heated to 70° C. for 2.0 hours. The analysis showed 0.81 mmoles propylene oxide (58% yield), 0.55 mmoles acetone (39% yield) and 0.06 mmoles propylene carbonate (4% yield) to have formed. 1.40 mmoles of thallous bicarbonate (16% conversion) was detected in a solution having a pH =7.9.
