    摘要: PROBLEM TO BE SOLVED: To provide a method for producing a monocyclic aromatic hydrocarbon capable of suppressing extreme heat generation upon hydrogenation reaction and avoiding increase of equipment cost of a hydrogenation reactor.SOLUTION: The method for producing the monocyclic aromatic hydrocarbon having 6-8 carbon atoms has a breakdown/modification reaction step of bringing a starting material oil in reactive contact with a catalyst to obtain a product containing the monocyclic aromatic hydrocarbon, a purification/collection step of purifying and collecting monocyclic aromatic hydrocarbon isolated from the product generated in the breakdown/modification step, a dilution step of adding a dilution agent to a heavy fraction isolated from the product generated in the breakdown/modification step, a hydrogenation reaction step of hydrogenating the mixture, and a recycling step of returning a hydrogenated product of the mixture obtained in the hydrogenation reaction step to the breakdown/modification reaction step.

    摘要: PURPOSE: To obtain a reduced form of an aldehyde compound at relatively low temperatures and at high reaction rate without the need of using a large quantity of a transition metal complex, by adding a ruthenium complex and an organic hydroperoxide to the aldehyde compound to carry out a decarbonylation. CONSTITUTION: This reduced form is obtained by incorporating an aldehyde compound with a ruthenium complex of the formula RuX2 Ln (PPh3 )n (Ph is phenyl; X is an anionic ligand capable coordinating with an Ru atom; L is a neutral ligand capable of coordinating with an Ru atom; (n) is 0-3; (m) is 1-4; (m+n) is a natural number of to 5×10, and the molar ratio of the organic hydroperoxide to the aldehyde compound is normally 0.5-5. The decarbonylation is pref. carried out using, a reaction solvent, e.g. an alkane as a raw material for the organic hydroperoxide at 80-160 deg.C.
