Embodiment 1

[0136] according to figure 1 The scheme shown oxidizes tetradecane. First, the oxidation reaction device will be described. Oxygen is supplied from an oxygen cylinder (not shown) to the ozone generator 3 through the oxygen introduction channel 2, and a part of the oxygen is converted into ozone. Nitrogen is introduced into this gas from a nitrogen supply line (not shown) to form a mixed gas of oxygen-ozone-nitrogen. This mixed gas is supplied to a gas-liquid mixer (gas-liquid mixing unit) (material: PCTFE (Dyflon)) 5 through a gas introduction channel 4 . On the other hand, tetradecane (liquid) as a reaction substrate was supplied to the gas-liquid mixer 5 through the hydrocarbon supply channel 1 (note that the hydrocarbon supply channel 1 was not used in this example). figure 2 A schematic view of the gas-liquid mixer 5 viewed from the side is shown in . figure 2 The upper part is equivalent to the top of the gas-liquid mixer. in addition, image 3 The middle shows a ...

Embodiment 2

[0147] The same operation as in Example 1 was performed except that the reaction substrate was changed from tetradecane to 2,2,4-trimethylpentane. As a result, the conversion rate of the substrate was 3.8%.

Embodiment 3

[0149] The same operation as in Example 1 was performed except that the reaction substrate was changed from tetradecane to n-heptane. As a result, the conversion rate of the substrate was 2.9%.

Abstract

Provided is an oxidation reactor with which hydrocarbons can be oxidized efficiently in terms of both reaction efficiency and energy efficiency. This oxidation reactor is equipped with: a liquid introduction channel through which a liquid containing a hydrocarbon as a reaction substrate is introduced; a gas introduction channel through which gases comprising oxygen and ozone are introduced; a gas / liquid mixing part in which the liquid introduced through the liquid introduction channel is mixed with the gases introduced through the gas introduction channel; and a flow reactor containing an oxidation catalyst fixed thereto or packed thereinto. The oxidation reactor is characterized in that the gas / liquid mixing part has, disposed inside the channel, a movable particle which rotates and / or moves to mix the liquid with the gases and thereby form a gas / liquid slug flow, the gas / liquid slug flow being introduced into the flow reactor.

Description

technical field [0001] The present invention relates to an oxidation reaction device and a method for producing an oxide using the oxidation reaction device. More specifically, it relates to an oxidation reaction device used when oxidizing a hydrocarbon as an organic substrate in the presence of oxygen and ozone to obtain an oxide, and a method for producing an oxide using the oxidation reaction device. This application claims the priority of Japanese Patent Application No. 2014-175313 for which it applied to Japan on August 29, 2014, and uses the content here. Background technique [0002] Oxidation reaction is one of the most basic reactions in the organic chemical industry, and various oxidation methods have been developed. Patent Document 1 describes a method of oxidizing a compound capable of generating radicals with molecular oxygen or the like using a fat-soluble imide compound as a catalyst. According to this method, various organic substrates can be oxidized to ob...
