Fundamentals of C4-Hydrocarbons,Depending on the number of attached hydrogen atoms there are C.-hydrocarbons which are saturated or contain double or triple bonds. Table 1.1 contains all the C.-isomers, arranged in the order of increasing unsaturation.

Production Scheme for C4-Hydrocarbons,The production scheme is intended to display the availability of amounts of raw materials, base chemicals or intermediates, together with their natural or synthetic sources and technological relations. It forms the basis for analyzing and forecasting the quantitative suitability and availability of a raw material for preparing chemical products.

Competition Factors of the C4-Hydrocarbons,The politico-economic process of operational productive performance is initiated by the demand of the ultimate buyers of the products. The consumers determine the type and amount of the products to be supplied through the purchasing power available to them in combination with the order or priority of their needs.

Analyses of Competition of C4-Chemical Products,The efficiency of conversion into propulsion performance of the energy content of fuel for internal combustion engines increases with a higher compression ratio of the fuel-air mixture on ignition. The theoretical relationship for Otto engines is given in Fig. 6.1.

François-Paul Briand,Michael Wirschingikewise forms azeotropes with .- or .-2-butenes, differing only slightly in boiling point from butadiene. Finally, the boiling points of .-butene and 1-butene are so near that their distillative separation is uneconomic (Table 3.1).
