Dichloromethane methylene

Chlorination of various hydrocarbon feedstocks produces many usehil chlorinated solvents, intermediates, and chemical products. The chlorinated derivatives provide a primary method of upgrading the value of industrial chlorine. The principal chlorinated hydrocarbons produced industrially include chloromethane (methyl chloride), dichloromethane (methylene chloride), trichloromethane (chloroform), tetrachloromethane (carbon tetrachloride), chloroethene (vinyl chloride monomer, VCM), 1,1-dichloroethene (vinylidene chloride), 1,1,2-trichloroethene (trichloroethylene), 1,1,2,2-tetrachloroethene (perchloroethylene), mono- and dichloroben2enes, 1,1,1-trichloroethane (methyl chloroform), 1,1,2-trichloroethane, and 1,2-dichloroethane (ethylene dichloride [540-59-0], EDC). [Pg.506]

Indoles. CA, 74, 87819 (1971). First prepare polyphosphoric acid by adding 2 parts P2O5 to one part phosphoric add. Add 3.3 g of phenyl hydrazine and 4 g of phenylacetone (or an equimolar amount of ethylacetone) to 30 g of polyphosphoric acid and heat for 20 min at 135° in a nitrogen atmosphere. Pour over 200 ml of water and extract with dichloromethane (methylene chloride) to get 2-benzylindole in 43-47% yield. Ethylacetone gives 2-ethylindole in about 30% yield. [Pg.80]

Solvents WW-dimethylformamide (DMF VWR), methanol or ethanol (VWR), V-methylpyrrolidone (NMP Fluka), diethyl ether (VWR), dichloromethane (methylene chloride, DCM VWR). Solvents for washing steps should be of at least ACS quality, whereas solvents for dissolving reagents must be amine and water free. Organic solvents (except for methanol and ethanol) should be stored in the dark. [Pg.48]
