The inherent viscosity of the polymer was calculated from viscosity measurement of a dilute polymer solution (Concentration 0.5 g/dL) in (40:60) phenol: tetrachloroethane
as a solvent mixture at 30AdegC.
is a chlorinated derivative of ethane.
The treated fabric contains the toxicity of 1,1,2,2 Tetrachloroethane
and this amount of Tetrachloroethane
determined in the fabric by gas chromatography was as under:
EPA 8240-B method (Anonymous, 1994) was used for determination of tetrachloroethane
, THM and 1-2 dichloroethane.
The UV/oxidation technology ([O.sub.3]/[H.sub.2][O.sub.2]/UV system) has been applied successfully for the removal of volatile organic contaminants (VOC) (benzene, acetone, dichloroethane, tetrachloroethane
, etc.) from groundwater in San Jose, CA (USA) .
Those that are regarded as nondegradable are chloroform, trichloroethane, and tetrachloroethane
. These concerns have led to interest in using general fate models (GFMs) to simulate the fate of toxic organic compounds.
[the circadian dependent effect of trichloroethylene on spontaneous locomotor activity and of tetrachloroethane
on mortality in mice].
Blanc then describes the use of benzene as a solvent for rubber cement and its attendant effects on the bone marrow, and polymer sealants such as nitrocellulose dissolved in tetrachloroethane
when benzene was diverted to munitions manufacture during World War I.
Phenol (AR) and tetrachloroethane
(AR) were all purchased from Tianjin Guangfu Fine Chemical Research Institute and were used as received.
VOCs not meeting inclusion criterion: 1,1,2,2- tetrachloroethane
, 1,1,2-TCE, 1,1-dichloroethane, 1,1-dichloroethene, 1,2-DCB, 1,2-dichloroethane, 1,2-dichloropropane, 1,3-DCB, bromodichloromethane, bromoform, carbon tetrachloride, chlorobenzene, chloroform, cis-1,2-dichloroethene, dibromochloromethane, dibromomethane, methylene chloride, trans-1,2-dichloroethene, and trichloroethene.
Analytical grade EG, acetic anhydride, pyridine, potassium hydroxide, phenol, tetrachloroethane
(TCE), sebacic acid, glycerol, p-toluene sulphonic acid (p-TSA), zinc acetate (ZnAc), xylene, and methyl ethyl ketone (MEK) were purchased from SD Fine chemicals India and used without any further purification.
This value of 2.2 is similar to values reported for ethyl acetate and three times lower than reported for tetrachloroethane
in rainbow trout (Fitzsimmons et al.
