オキシラン化合物の製造方法
Document Type and Number:
Japanese Patent JP4495272
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing an oxirane compound in a high yield and in a high selectivity by reacting an olefinic compound with ethylbenzene hydroperoxide in the presence of a specific titanium-containing silicon oxide catalyst. SOLUTION: This method for producing an oxirane compound comprises reacting an olefinic compound with ehylbenzene hydroperoxide. Therein, the reaction is carried out in the presence of a catalyst comprising a titanium- containing silicon oxide satisfying all of the following conditions (1) to (5). (1), The average pore diameter of the silicon oxide is >=10 Å. (2), The pores in a volume of >=90% based on the total pore volume have pore diameters of 5 to 200 Å. (3), A specific pore volume is >=0.2 cm3/g. (4), The catalyst is obtained by using a specific quaternary ammonium ion as a template agent and subsequently extracting off the template agent by a solvent extraction method. (5), The silicon oxide does not have a peak exhibiting an interplanar spacing d in an X-ray diffraction.
