Title:
Cyclohexane epoxidation method
Document Type and Number:
Japanese Patent JP6339498
Kind Code:
B2
Abstract:
A process of oxidizing cyclohexane, comprising feeding cyclohexane, an aqueous hydrogen peroxide solution and optionally an organic solvent into a reaction zone through a feed inlet thereof under the oxidation reaction conditions for contact, and providing all or most of the oxidation product at the reaction zone bottom, wherein a part or all of the packing in the reaction zone is a titanium silicate molecular sieve-containing catalyst. The process of oxidizing cyclohexane according to the present invention carries out the oxidation in the reaction zone, which, firstly, utilizes the latent heat from reaction sufficiently so as to achieve energy-saving; secondly, increases the yield of target product and the availability of oxidizer; and thirdly, allows the separation of the oxidation product from the raw material cyclohexane as the reaction proceeds, such that the cost for subsequent separations can be saved.
