METHOD FOR PROCESSING COMPOSITIONS CONTAINING 1,1,2,2-TETRAMETHOXYETHANE AND GLYOXAL DIMETHYL ACETAL

Disclosed is a method for processing an aqueous composition containing 1,1,2,2-tetramethoxyethane, glyoxal dimethyl acetal, and methanol by means of distillation. Said method is characterized in that the composition is processed in a partition column so as to form low-boiling, medium-boiling, and high-boiling fractions. A partition is disposed in the longitudinal direction of the partition column such that a common top column area, a common bottom column area, a feeding zone comprising a rectification section and a stripping section, and a removing zone encompassing a stripping section and a rectification section are created. The aqueous composition is delivered to the central area of the feeding zone.

ELECTROCHEMICAL OXIDATION OF DIOXENE AND CHLORODIOXENE IN ALCOHOL SOLUTIONS

2,3-Dialkoxy-1,4-dioxanes and 2-chloro-2,3-dialkoxy-1,4-dioxanes are formed during the anodic oxidation of dioxene and chlorodioxene respectively in the presence of various alcohols.The reaction of the products with sodium methoxide gave ortho esters of a new type.During hydrolysis of 2-chloro-2,3-dimethoxydioxane glyoxylic acid or its ester are obtained depending on the conditions.
