Separation of chlorosilanes by extractive distillation - …

25/10/1983· By "close-boiling chlorosilanes" we mean those chlorosilanes which have boiling points within about 10 C. of each other at atmospheric pressure. The separation can be carried out in any suitable manner such as by mixing the chlorosilanes and sulfolane in a retort and then heating to remove the lower-boiling chlorosilane.
