Title:
【発明の名称】オスミウムの酸化物不均一系触媒、その製造方法およびオレフィン系化合物をグリコールに転化する為のその用途
Document Type and Number:
Japanese Patent JPH04505884
Kind Code:
A
Abstract:
The invention relates to oxidic heterogeneous catalysts based on nitrogen-containing polymers to which oxidic osmium is bonded in an oxidation number lower than the octavalent number, their use in converting olefinic bonds into vicinal diols and a process for such hydroxylation. The invention also relates to a process for manufacturing catalysts based on nitrogen-containing polymers on which osmium oxide is precipitated from a solvent, in which (a) an osmium oxide soluble in alcohols and/or ethers is reacted in the presence of such an alcohol and/or ether with a nitrogen-containing polymer which is insoluble in water and the related alcohol and ether and the catalyst is separated out and dried, or (b) an osmium carbonyl compound is reacted in an alcohol and/or ether with nitrogen-containing polymers and the osmium is oxidised with H2?O2? to a higher but not the octavalent oxidation number.
