A PROCESS FOR THE HYDROFORMYLATION OF SULFUR-CONTAINING THERMALLY CRACKED PETROLEUM RESIDUA AND NOVEL PRODUCTS THEREOF

摘要

catalytic process for hydroformylation of olefin cracking residue containing sulfur for aldehydes and alcohols. the homogeneous catalysts are complexes of transition metal carbonyls.the preferred catalysts for the hydroformylation medium under reduced pressure of cobalt carbonyl complex of rhodium hydride and carbonyl groups in which the coordination of carbonyl groups have been replaced by coordination of trivalent phosphorus.in a preferred mode of high pressure hydroformylation feedstock naphtha, distillate, and sulfur are recovered under vacuum by cracking at high temperature. products containing more than 20% from olefins olefins 1-n constituting the main guy.these components are an olefin hydroformylation in the presence of a cobalt carbonyl complex to give a new type of semi linear aldehydes and / or an alcohol containing an average of less than one alkyl chain per molecule.the alcohols are converted to dialkyl phthalates and other esters having a unique combination of properties, and useful for producing plastifiantes, new surface active agents, in particular, their ethoxylates. we prefer to use for the preparation of products with the minimum concentrations of sulphur distillate fractions of small residues of cracking.in the range of c6 to c11 carbon fractions can be obtained with very low levels of aromatic hydrogen carbide and thiophene.the fractions enriched in linear olefins can be used advantageously as starting materials in the preparation of derivatives of hydroformylation, low sulfur containing alcohols and similar products increased linearity.
