Process for producing 1-hexene

Titanium-containing solid catalyst

A method for producing propylene oxide by reacting a hydroperoxide with propylene by a fixed bed flow reaction in the presence of a titanium-containing solid catalyst, wherein said catalyst is diluted with a diluent comprising a solid inorganic compound which is inactive to the reaction and has a heat conductivity at 400 K of about 10 Wm.sup.-1 K.sup.-1 or more.

Method for producing propylene oxide

A heterogeneous catalyst used for producing an oxirane compound by reacting an olefinic compound with an organic hydroperoxide which catalyst is substantially insoluble in the reaction mixture, comprises at least one silicon compound, selected from the group consisting of silica and inorganic silicates, in chemical combination with an oxide or hydroxide of titanium, and is obtained by a process comprising the steps of

Process of making a catalyst for producing oxirane compounds

The present invention provides a process for producing olefin having a terminal double bond by trimerizing at least one monomer selected from a group consisting of ethylene, propylene, and 1-butene, which comprises using a catalyst comprising a product prepared from (1) component (A): a chromium compound represented by the formula �1!

Process for producing olefin having a terminal double bond

A process for producing propylene oxide which comprises reacting a raw material solution which is a solution of ethylbenzene hydroperoxide in ethylbenzene obtained by liquid phase autoxidation of ethylbenzene with propylene in the presence of a Ti-containing solid catalyst to give propylene oxide, said raw material solution being a solution prepared by washing a solution of ethylbenzene hydroperoxide in ethylbenzene obtained by liquid phase autoxidation of ethylbenzene with an aqueous alkali solution to bring a lactic acid concentration to 5 ppm by weight or less.

Process for producing propylene oxide
