摘要： Process for the preparation of dienes and/or trienes comprising reacting a polyolefinically unsaturated com- pound in the presence of a heterogeneous disproportionation catalyst with a compound according to the general formula
wherein R 1 and R 2 , which may be the same or different, each represent an alkyl, aryl, alkaryl or aralkyl group which may or may not contain one or more inert substituents or R 1 and R 2 form part of a cyclic structure together with the carbon atom to which they are attached. Isononadiene (2,6-dimethyl-1,5-heptadiene) and/or 2,6,10-trimethyl-1,5,9-undeca- triene can be obtained by reacting cis-1,4-polyisoprene with isobutene in the presence of a heterogeneous disproportionation catalyst. Also included are the dienes and/or trienes produced by the defined process.-

摘要： Process for producing a hydrowax comprising the steps of
(a) hydrocracking a blend obtained by blending at least one distillate fraction and a deasphalted oil (DAO); (b) separating from the hydrocracker effluent a fraction of which at least 90% by weight has a boiling point of 370 °C or higher (the 370+ fraction); and (c) separating the 370+ fraction in a top-fraction and a bottom-fraction at an effective cutpoint below 600 °C, thus yielding the hydrowax as the top-fraction. The hydrowax thus produced is a very suitable feedstock for a steam cracker for the production of ethene. The hydrowax can also be very suitably applied as a feed for the production of lubricating base oils.-
