ANALYSIS OF ALCOHOLS ETHOXYLATION PRODUCTS WITH THE USE OF GAS-CHROMATOGRAPHY

A method has been developed for analytic investigation of methyl, ethy l and butyl alcohols ethoxylation products. The products are mixtures containing various amounts of alcohols as well as methyl, ethyl and bu tyl monoethers of mono-, di-, tri- and tetraethylene glycols. The anal ysis employed a glass column filled with Chromosorb G AW DMCS 100/120 mesh, and two stationary phases: OV-225 3 %(m/m) -sector of 0.90 m, an d OV-17 3 %(m/m) - sector of 2.7 m. Separation was carried out at temp eratures of 70-200-degrees-C with linear programming of heating rate 4 -degrees-C min-1.
