Reaction Steps

Into a 500 ml Hastelloy stirred autoclave, there was introduced 10.6 g of cuprous iodide, 9.24 g of potassium iodide, 6.15 g of cupric carbonate dihydroxide, 150 ml of water, 16.0 g of propylene, 600 psia of carbon dioxide, and 200 psia of oxygen. The reaction mixture was heated at 120° C. for 5 hours. The workup procedure was essentially the same as described in Example 1. The reaction produced 41 mmoles of propylene carbonate, 7 mmoles of propylene glycol, 7 mmoles of propylene iodohydrins, 7 mmoles of acetone, 2 mmoles of propanal, and 1 mmole of propylene oxide. The productivity rate amounted to 0.086 mole/liter-hour. In a comparison of Example 11 with Example 13, the use of ferrous iodide gave a higher productivity rate than that obtained using cuprous iodide.
