Estimating the term…
A method for carrying out a reaction of one substance capable of being activated by a catalyst with another substance capable of reacting with said one substance activated, characterized in that the substance capable of being activated is activated by passing the substance through a diaphragm type catalyst and the reaction is thus performed in one reaction step; a method for producing an aromatic alcohol utilizing the above method; and a reaction apparatus suitable for these reactions. In the method, one substance is activated by passing through a diaphragm type catalyst and an objective reaction is carried out by using the activated substance, and the reaction can be performed in one reaction step and with safety. Moreover, the contact of the above activated substance with a compound to be reacted therewith can be freely controlled, and therefore, over-reaction can be prevented and an objective product can be produced in high yield. The method is thus markedly advantageous from an economical view point as a commercial process for producing oxygen-containing organic compounds such as an aromatic alcohol, a ketone, an aldehyde, a carboxylic acid and an epoxide.

(Amended) A method for producing an oxygen-containing organic compound comprising providing a reactor with a plurality of adjacent chambers partitioned by a diaphragm type catalyst that can activate a substance permeating therethrough, causing hydrogen gas to be activated by the diaphragm type catalyst to circulate in one of the chambers, causing a hydrocarbon and oxygen to be reacted with the activated hydrogen to circulate in the other chamber, activating the hydrogen while permeating through the diaphragm type catalyst, and reacting the activated hydrogen with the hydrocarbon and oxygen.

A method for producing an aromatic alcohol by reacting oxygen, hydrogen, and an aromatic hydrocarbon in one step, wherein hydrogen activated while permeating through a diaphragm type catalyst is reacted with an aromatic hydrocarbon and oxygen.
A reaction apparatus having a reactor partitioned by a diaphragm type catalyst into a plurality of adjacent chambers, one of the chambers being designed to cause a gas of a substance to be activated to circulate and the other chamber being designed to cause a compound to be reacted with the activated substance to circulate, wherein the substance to be activated is activated while permeating through the diaphragm type catalyst and the activated substance is reacted with the compound to be reacted with the activated substance.
A reaction apparatus comprising one or more internal cylinders and an external cylinder covering the internal cylinders, wherein the internal cylinders are partially or entirely constituted by a diaphragm type catalyst that can activate a substance permeating therethrough, the external cylinder is provided with an inlet port and an outlet port to cause either a gas of a substance to be activated or a compound to be reacted with the activated substance to circulate, and the internal cylinders are provided with an inlet port and an outlet port to cause the other gas to circulate.
