An apparatus for preparing a dialkyl carbonate comprises means for reacting an alkanol, oxygen, carbon monoxide, and a catalyst to form a mixture comprising a dialkyl carbonate, an alkyl chloroformate, hydrochloric acid, water, carbon dioxide, and carbon monoxide; means for separating from the mixture a gaseous fraction comprising carbon monoxide and alkyl chloroformate; and means for removing alkyl chloroformate from the gaseous fraction.

Apparatus for preparing a dialkyl carbonate

A method of preparing a dialkyl carbonate includes reacting an alkanol, oxygen, carbon monoxide, and a catalyst to form a mixture that includes a dialkyl carbonate and an alkyl chloroformate. The mixture is separated into a liquid fraction and a gaseous fraction, and alkyl chloroformate is removed from the gaseous fraction. Also described is an apparatus for carrying out the method. The method is particularly useful for preventing corrosion in a cold wash unit that removes further organic impurities from the gaseous fraction.

Residual silicone from direct process manufacture of chlorosilanes is stabilized for transportation and disposal by pelletizing finely divided particles of finely divided residual silicon powder contaminated with chlorine, hydrogen, and oxygen and highly reactive and exothermic upon exposure to moisture, and impregnating the pellets with an organic binder.
