comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Biochemical and Histopathological Effects of Acute Exposure to Vinyl Acetate Monomer Vapour in Wistar Rats

Background: Vinyl acetate monomer is a commodity chemical widely used in the manufacturing of various products. The chemical is hazardous and exposure to it may occur in both occupational and non-occupational settings. The aim of this study was to characterize the effects of short-term exposure to Vinyl Acetate Monomer (VAM) vapour on the liver and lungs of Wistar rats. Methods: Mice weighing ...

prediction of optimum time for oxygen clearance in solution polymerization of vinyl acetate in isopropyl alcohol

as we know oxygen is one of the main inhibitors of polymerization of vinyl acetate. therefore, nitrogen is used in order to make sure of system's high purity. to maintain purity it is necessary to find out the rate of the oxygensolution in polymerization system under different conditions of polymerization. it is concluded that incoming nitrogen to the system would remove the oxygen from th...

A Kinetic Study of the Emulsion Polymerization of Vinyl Acetate

This report deals with the chemically and the radiation-initiated emulsion polymerization of vinyl acetate. In experiments with potassium persulphate as initiator and sodium lauryl sulphate (SLS) as emulsifier the rate of polymerization is approximately proportional to the square root of initiator concentration and to the 0.25 power of the number of particles. The number of particles is proport...
