    Abstract: A start-up process for epoxidation of ethylene is provided. The process includes initiating an epoxidation reaction by reacting a feed gas composition in the presence of an epoxidation catalyst at a first temperature of about 180° C. to about 210° C. The first temperature is increased to a second temperature of about 230° C. to about 290° C., over a time period of about 6 hours to about 50 hours, while simultaneously adding a sufficient concentration of moderator so that the amount of moderator adsorbed on the catalyst after achieving the second temperature is from about 10 to about 50 g/m3 of catalyst. The second temperature is maintained for about 50 hours to about 350 hours, while regulating the feed gas composition to contain about 0.5% to about 25% CO2. The second temperature is decreased to a third temperature, while simultaneously increasing moderator concentration to a level greater than the sufficient concentration.

    Abstract: Alkylene carbonates, particularly ethylene carbonate, are prepared by the reaction of an alkylene oxide with carbon dioxide in the presence of a catalyst at temperatures in the region of the critical temperature of carbon dioxide, preferably 25.degree.-70.degree. C. and at autogenerated pressures, typically 30 to 200 kg/cm.sup.2 gauge. The conversion of alkylene oxide to alkylene carbonate can be carried out in the presence of water while minimizing the undesirable hydrolysis of the carbonate to athe corresponding alkylene glycol. With certain catalysts the presence of water improves the selectivity to the formation of the carbonate.
