Abstract : Batch and continuous units are described for separating binary azeotropes consisting of SiCl4 plus acetonitrile(CH3CN) (b.p. 49.1C) and (CH3)3SiCl and CH3CN (b.p. 56.5C). The 1st unit consists principally of 3 rectification columns. In the 1st, the low-boiling and higher boiling components are separated from the crude SiCl4 and (CH3)3SiCl mixture. In the second and third, SiCl4 and (CH3) 3SiCl are separated. The experimental results were in close agreement (9 to 12 percent deviation) with those calculated. (Author)
