摘要: Supercritical and near critical fluids are used to fractionate biomass materials in two steps. In the first step, the biomass is exposed to elevated pressure supercritical or near critical fluid to bring about disruption of the biomass. In the second step, the disrupted biomass is subjected to a multiplicity of supercritical or near critical fluid extraction steps, with different solvation conditions used for each fraction. Thus, fractionation of the biomass is effected.

摘要: Vinylcycloalkanes of the formula R-CH CH2 wherein R is a cycloaliphatic radical with 5 or 6 carbon atoms which can be substituted by substituents selected from the group consisting of alkyl groups containing 1 to 6 carbon atoms and saturated chains containing 1 to 6 carbon atoms and a hetero-atom selected from the group consisting of sulfur, oxygen and nitrogen are prepared by reacting vinyl chloride and an organometallic compound of the formula (R)n-M. The radical R of the organometallic compound is defined as above, M is a lithium atom, a cadmium atom or a magnesium-halogen group and n is equal to 1 when M is lithium or the magnesium-halogen group and is equal to 2 when M is cadmium. A catalyst is used which consists of a metal from Group VIII of the Periodic Table or a compound of a metal from Group VIII of the Periodic Table and at least one compound of an element from Groups VA and VIA of the Periodic Table of elements which is complexed with the metal from Group VIII or the compound of a metal from Group VIII.
