- An improved method of synthesizing a cyclocarbonate from an epoxy compound and carbon dioxide at low pressure and temperature in a reactor, the method comprising the steps of;
a) supplying a catalyst to the reactor;
b) introducing the epoxy compound to the catalyst-containing reactor to create a reactionary mass in the reactor; and
c) feeding carbon dioxide to the reactor through a turbine mixing device and a gas entrainment impeller directly into the reactionary mass, the reactionary mass being saturated with the carbon dioxide and reacting to form the cyclocarbonate. - View Dependent Claims (63, 64, 65, 66)
