BRIGHTENERS ON ETHYLENE CHLOROHYDRIN BASE IN ELECTROCHEMICAL NICKEL PLATING

The possibility of using products obtained from ethylene chlorohydrin – 2- hydroxyethylisothiuronium chloride, mono- and dichalcogen derivatives of diethylene glycol, in the process of brilliant electrochemical nickel plating is considered.

THE EFFECT OF SUBACUTE INTOXICATION WITH ETHYLENE CHLOROHYDRIN ON IMMUNE RESPONSES, TH1 AND TH2 LYMPHOCYTE FUNCTION AND CYTOKINE LEVELS IN RATS BLOOD

In experiments on outbred albino rats, it was established that subacute intoxication with ethylene chlorohydrin (0.2 LD50 daily for 4 days) causes a decrease in Th1 and Th2 lymphocytes function to the same extent, diminishes parameters of humoral and cellular immune responses and the content of immunoregulatory cytokines IFN- , IL-2, IL-4 in blood, increases concentrations of pro-inflammatory cytokine IL-6 and anti-inflammatory cytokine IL-10.

A New Technological Study on Synthesis of Bis(2-chloroethoxy)Methane

bis(2-chloroethoxy)methane was synthesized by the reaction of ethylene chlorohydrin and Oligopolyformaldehyde under sulfuric acid catalysis. optimum reaction conditions obtained were as follows: the molar ratio of Oligopolyformaldehyde and ethylene chlorohydrin of 1.2:2, catalyst dosage was 5‰mass fraction of ethylene chlorohydrin, toluene were chose as water-carrying agent, All reactant were refluxed on temperature of 110°C until no water generated. Under the optimum conditions the yield of bis(2-chloroethoxy)methane was 97.7%. The structure of bis(2-chloroethoxy)methane were conformed by ATR IR. The purity of bis(2-chloroethoxy)methane were 99% by gas chromatographic detection.
