The formed polymer was found to be insoluble in many common organic solvents such as THF, DMSO, 1,4-doixane, diethylether and methanol but soluble in chloroform, dichloromethane, and (40:60) phenol: tetrachloroethane
The Zhongda oil refinery has brought a large amount of toxic substance to Kyrgyzstan last spring - 1 ton of tetrachloroethane
, MP Almasbek Akmatov (Bir Bol) said at the session of Parliament today.
The results of this experiment clearly indicated that, apart from transformation to PCE via [beta] reductive elimination, HCA can also undergo hydrogenolysis to produce pentachloroethane (PCA) and tetrachloroethane
(TeCA) and then trichloroethane (TCA) and dichloroethane (DCA).
According to Ngwezi, the group of chemicals consists of a mixture of organic compounds and metals namely: benzene, butadiene, carbon disulphide, chloroform, ethylene oxide, hexachlorobenzene, tetrachloroethane
, methanol, sulphur dioxide, toluene, lead, mercury and cadmium.
As the solvents, the phenol (Tianjin Kermel Chemical Reagent Co., Ltd) and the tetrachloroethane
(Tianjin Guangfu Fine Chemical Industry Research Institute, China) were used.

Most commonly found chemical pollutants were benzene, benzo[a]pyrene (BaP), 1-2 dichloroethane, epichloridine, tetrachloroethane
, trihalomethane and acrylamide.
(7) While PDB was the only chlorine-containing compound to be found a priority hazard, there were lots of chlorine containing chemicals lower down on the list including hexachlorobutadiene, benzyl chloride, vinyl chloride, methylene chloride, tetrachlorothene, dichloropropane, tetrachloroethane
, dichloroethane, trichloroethene, and, of course, chlorine.
In addition to methane and TNMHC, 16 hydrocarbon species were selected and used to calculate percent control efficiency including freon, methylene chloride, 1,1,1-trichloroethane, tetrachloroethane
, trimethylbenzenes, 1,4-dichlorobenzene, toluene, xylenes, and ethylbenzene.
Associations of ASD with styrene, butadiene, and tetrachloroethane
were elevated for boys and not girls, whereas the association of ASD with mercury compounds were elevated for girls and not boys (Kalkbrenner et al.
