摘要： The invention relates to a process for the manufacture of oxiranes of the formula ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are hydrogen, methyl and/or ethyl and the total amount of carbon atoms of R.sub.1, R.sub.2 and R.sub.3 is utmost 2 wherein olefin is subjected to an electrochemical system and reacts with a chlorine-containing anolyte to form an olefin chlorohydrin, with the latter subsequently reacted to form the oxirane.The oxiranes are known compounds and are extensively used in the chemical field, for example, in the manufacture of detergents, polyethers, etc.

摘要： The processing of liquid chlorinated hydrocarbon residues, which may contain solids and which form viscous to solid deposits during the separation of readily boiling components, into(1) distillable organic components,(2) hydrogen chloride, and(3) solid matter with a low chlorine content,is improved by gently concentrating the residues in a first step and, in a second step, decomposing the residues at temperatures of about 200.degree.-400.degree. C., preferably 270.degree.-330.degree. C., with a continuous separation of the vapor phase components from the solid components.
