reaction in the presence of a carbodiimidization catalyst, in which process tetrachloroethylene, trichloroethylene, tetrachloroethane, trichloroethane or a mixture thereof is used as the polymerization solvent,
1- dimethoxyethane, dimethyl ether, 2-ethylhexanol, 2-ethylhexylamine, n-heptane, n-hexane, isoprene, isopropyl alcohol, diisopropyl ether, methanol, methyl ethyl ketone, oxygen, n-pentane, phenol, propane, n-propyl alcohol, propylene, pyridine, styrene, tetrachloroethylene, toluene, ...
These include the aromatic hydrocarbons (e.g. benzene, toluene, or xylene), aliphatic hydrocarbons (e.g. hexane or heptane), chlorobenzene, tetrachloroethylene, and any other inert solvent which will not destroy the catalyst. The temperature is not critical and may be as in conventional practice...
The anthropogenic and biogenic origin of low molecular weight halocarbons in a polluted fjord, the Idefjordendoi:10.1016/0025-326X(86)90252-3Three halocarbons—chloroform, tetrachloroethylene and bromoform—have been used as tracers to study the water mixing in the Idefjorden, a fjord on the ...
Surface tension of polymer solutions. III. Effect of molecular weight distributionThe lattice-theory equations for the surface tension of polymer solutions based on the parallel-layer model have been extended to include more than two components. The surface tensions of tetrachloroethylene solutions of ...
carbodiimide, for example, in the presence of 1-phenyl-3-methylphospholene oxide in a chlorinated aliphatic hydrocarbon (e.g. tetrachloroethylene) (in a concentration <=15wt.%, desirably <=10wt.%) to obtain a polycarbodiimide solution useful for the production of a varnish, a film or the ...
A solvent may be present during the mixing of the catalyst components and during the polymerization and listed are benzene, xylene, chlorobenzene, tetrahydronaphthalene, decahydronaphthalene, cyclohexane and tetrachloroethylene. Polymerization is carried out in the absence of oxygen and water, e.g. in ...
Renal cytochrome P450s and flavin-containing monooxygenases : potential roles in metabolism and toxicity of 1,3-butadiene, trichloroethylene, and tetrachloroethylene / Adnan A. Elfarra -- Experimental approaches for the study of cytochrome P450 gene regulation / Hollie I. Swanson [and others] -- ...
(2) may be chosen from hydrocarbons, such as hexane, heptane, petroleum ethers, naphtha, cyclohexanes and halogenated hydrocarbons, containing fluorine and/or chlorine atoms, such as methylene chloride, chloroform, tetrachloroethane, tetrachloroethylene or trichlorotrifluoroethane. Only such halogenated ...
hydrocarbons, particularly hexane. Non-limiting illustrative examples of solvents are butane, pentane, hexane, heptane, cyclopentane, cyclohexane, cycloheptane, methyl cyclopentane, methyl cyclohexane, isooctane, benzene, touene, xylene, chloroform, chlorobenzenes, tetrachloroethylene, dichloroethane and ...
