Abstract
1,142,047. Alkylbenzenes. PIRELLI S.p.A. 4 July, 1966 [17 Nov., 1965], No. 29854/66. Heading C5E. [Also in Division H1] An alkyl benzene for impregnating electric cables and having a molecular weight in the range 200 to 400 is prepared by alkylation of benzene with aliphatic chloro-derivatives and refining the product by treatment with absorbing material, the alkyl benzene having a linear or branched chain containing 9 to 11 carbon atoms, a viscosity in the range of 2 to 10 centistokes at 20‹ C. and a Marcusson flash point in the open cup higher than 100‹ C. The absorbing material may be silica gel, bleaching clay, alumina or active carbon.
