SEPARATION OF TAGGED COMPOUNDS BY THE METHOD OF GASEOUS CHROMATOGRAPHY,
Abstract
Trimethylethoxysilane and dimethylethoxysilane that had been tagged with deuterium were separated by preparative gaseous chromatography. The basis part of the chromatograph was a column of 2-meter steel tubes with 30-mm diameter, connected by U-shaped passages, so that the column was 7 meters long in all. The samples were vaporized and fed by a nitrogen gas carrier stream into the column where they were subdivided into their components. The divided fractions were directed, with the aid of a sampling device of 7 electromagnetic valves, into proper traps where they were frozen out by liquid nitrogen. At a working temperature of the column of about 100C, mixtures of compounds with boiling points up to 160-170 C could be separated.
