Baj et al., in a setting of low level chronic exposures to phenol (0.34 ppm), formaldehyde and isomers of organic chlorohydrocarbons used as a liquid wood preservative, identified the presence of chronic complaints, among them cough and sore throat, which is consistent with these results [26].
Although the least toxic of the simple chlorohydrocarbons it is not without health risks and may be carcinogenic, as it has been linked to cancer of the lungs, liver and pancreas in laboratory animals.
The presence of water supports/accelerates many of the above reactions by hydrolyzing the POE esters to produce carboxylic acids, by increasing the solubility of the copper carboxylates, by promoting the corrosion of the steel surface (catalyzing dechlorination of the chlorohydrocarbons), by ionizing the carboxylic acid/other corrosive agents (zinc chloride used in brazing)] and by completing the electrical path of the electrochemical reaction in Step 5.
(62,63) These products contain chemicals such as acetone, toluene, alcohols, methyl ketones, chlorohydrocarbons and sometimes benzenes.
These polymers are not only similar to PEEK or PEK with excellent physical and mechanical properties, but also soluble in polar organic solvents, such as chloroform (CH[Cl.sub.3]), N,N-dimethyl formamide (DMF), N-methyl pyrrolidinone (NMP) and chlorohydrocarbons, which render its solutions castable.
Removal of chlorohydrocarbons is being investigated with the membrane preferentially transporting the minor component, the hydrocarbon, and producing an environmentally-clean retentate.
It eliminates the need for an external mold release and is designed to replace release agents that rely on CFC's or chlorohydrocarbons. (CIRCLE 20)
