Problems solved by technology

However, the hydrolysis temperature of aluminum alkoxide is higher than the azeotropic temperature of alcohol and water, and the alcohol released by hydrolysis will be drawn from the top of the reactor in the form of azeotrope, thus carrying more water, and alcohol-water separation is required. Process energy consumption is high

Embodiment Construction

[0014] The reactor of the present invention has a shell whose upper part is a cylinder and the lower part is a cone. The reactant inlet is arranged on the lower cone shell, the light product outlet is arranged on the upper part of the column shell, and the heavy product is arranged on the bottom of the cone shell. The product is exported, and a stirrer is installed in the shell. The reactor of the invention can carry out the reaction process of liquid-liquid two-phase continuous reaction and generate mutually immiscible light-heavy two-phase reaction products, and is especially suitable for the continuous reaction process of preparing metal hydroxide by hydrolysis of metal alkoxy compound. The reactor of the invention can carry out the hydrolysis reaction of the metal alkoxy compound continuously and controllably, at the same time, the amount of entrainment of alcohol in the metal hydroxide slurry is reduced, and the concentration of the slurry is increased.

Description

technical field [0001] The invention relates to a reactor for liquid-liquid two-phase contact reaction, specifically, a reactor for the reaction of two liquid reactants to generate two immiscible liquid phase products. Background technique [0002] High-purity metal hydroxides and oxides are a class of chemical materials that are widely used. For example, high-purity alumina is widely used in catalytic reforming, isomerization, hydrogenation and other oil refining catalytic processes, as well as in environmental protection fields such as automobile exhaust catalysts, water purifiers, and exhaust gas treatment. In recent years, the application fields of high-purity alumina have been further expanded, and there are more and more applications in emerging fields such as sapphire preparation, antistatic agents, and high-performance ceramics. High-purity magnesium oxide has excellent alkali resistance and electrical insulation at high temperatures, low thermal expansion coefficie...
