Studies in the Synthesis of Long Chain Aliphatic Compounds.
(University of Lagos, 1985-03) Hogan, Ephraim-Bassey
Studies in the synthesis of long chain compounds. This thesis is in two parts. Part 1 involves a study of the straight chain alkanes containing many carbon atoms. These are important analogues of polyethylene, a versatile industrial raw material. Although they can be derived from natural fats or waxes or from ethylene oligomers, they are never obtained pure. The physical properties of linear polyethylenes can be better understood if pure paraffins of comparable chain length could be synthesised and analysed. Here long chain aliphatic compounds with butyl side chain which could be used as models for low density polyethylene have been synthesised. The method employed was first proposed by M.O whitiny et al. The original schemes are reviewed. By this approach a number of long chain aliphatic compounds with a butyl branch had been synthesised.
