A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 49676-42-8, Name is Tris(2,4-dimethylphenyl)phosphine, molecular formula is C24H27P. In a Patent，once mentioned of 49676-42-8, category: chiral-phosphine-ligands
Olefin hydroformylation reaction process for producing aldehydes (by machine translation)
The invention relates to a process for the hydroformylation reaction process for producing aldehydes, mainly solves the olefin or in the side chain group-containing olefin reaction activity is poor, the weak acid catalytic system under the conditions of the problem of unstable. The present invention through the use of a olefin hydroformylation reaction process for producing aldehydes in the 60 – 130 C lower, reaction pressure 1.0 – 6.0 mpa conditions, uses aldehyde as solvent, rhodium compound, O-methyl phenyl group of a phosphorous compound, a pentavalent phosphorus-containing oxide hard alkali, bidentate phosphite composition catalytic olefin hydroformylation synthetic aldehyde; said olefin is isobutene, cis – 2 – butene, anti– 2 – butene, 2, 5 – dihydrofuran, 1 – butene, propylene, ethylene in at least one of the technical solution solves the above problems, can be used for olefin hydroformylation reaction production aldehyde in the process.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.category: chiral-phosphine-ligands, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 49676-42-8, in my other articles.
