Organotin Compounds and the Environment
Organotin compound that have at least one Sn-C bond have wide commercial applications as PVC stabilizer, antifouling agent in paint and as agrochemicals. The general formula for organotin compounds is R4SnX4 - n where R is normally alkyl or aryl groups and X=Cl-, OH-, CH3COO- . If n=3, the compound has the highest toxicity, for example Et3SnOAC has LD 50 4mg/Kg ( rats ) and this is the m...

متن کاملcomparison 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...
15 صفحه اولHousehold Coverage of Fortified Staple Food Commodities in Rajasthan, India
A spatially representative statewide survey was conducted in Rajasthan, India to assess household coverage of atta wheat flour, edible oil, and salt. An even distribution of primary sampling units were selected based on their proximity to centroids on a hexagonal grid laid over the survey area. A sample of n = 18 households from each of m = 252 primary sampling units PSUs was taken. Demographic...
متن کاملOrganotin compounds: industrial applications and biological investigation.
According to Ross (1), there are three main areas in which organotin compounds have product and process utility: (1) heat stabilizers; (2) catalytic agents; (3) biocidal compounds. Organotin derivatives account for the fourth largest production of organometallics amounting to about 3-4 million pounds per year as compared with about 485 million pounds per year for organolead compounds. Originall...
