Abstract
A simple and effective substitute for laboratory rectification apparatus is described. In the apparatus rectificaiton is combined with preparative gas chromatography, a mixture boiling in a wide temperature range being first separated in the rectification column and then continuously fed as distillate during the whole fractionation cycle into the chromatographic column. The temperatures of rectification and of the chromatographic columns follow the same increasing linear programme. Steam, used as carrier gas, passes through both columns and is condensed together with the separated fractions. The vapours are drawn through the columns by a vacuum at the end of the device. The apparatus can be used to fractionate petroleum and liquid by-products of coking and synthesis.
