Problems solved by technology

[0003] In view of the above-mentioned related technologies, the inventor believes that due to the strong corrosiveness of bromide ions, it will cause certain corrosion to the anode plate in the electrolysis equipment. During the long-term use of the electrolysis equipment, the anode will be corroded, which will affect the reactivity of the oxidation reaction of the anode. It is necessary to increase the electrolysis voltage or prolong the electrolysis time, which increases the energy consumption

preparation example 1

[0041] The titanium substrate includes a conductive frame 10 and a titanium mesh substrate 11 fixed in the conductive frame 10. The size of the titanium mesh substrate 11 is 20*15cm, the aperture of the titanium mesh substrate 11 is 6mm, and the thickness is 4mm. Get 20g of chloroiridic acid, add 175g of n-butanol, mix evenly, then add 45g of nano-tin dioxide and 1g of nano-titanium silicon molecular sieve, mix evenly, and make a slurry; apply the slurry evenly to the surface of the titanium mesh substrate, and control the coating. The amount of coating is such that the coating amount of iridium oxide on the surface of the titanium mesh substrate is 15g / ㎡, dried at 100°C for 60 minutes, and then baked at 450°C for 120 minutes. A catalytic coating is formed on the surface of the titanium mesh substrate 11, and several anode plates are prepared.

preparation example 2

[0043] The difference between Preparation Example 2 and Preparation Example 1 is that no titanium silicon molecular sieve is added in Preparation Example 2, and the other homogeneous Preparation Example 1 remains the same.

Description

technical field [0001] The application relates to the technical field of organic base production, in particular to a tetrapropylammonium hydroxide energy-saving production process and the tetrapropylammonium hydroxide aqueous solution prepared therefrom. Background technique [0002] Tetrapropylammonium hydroxide is an organic base, which is widely used as a template in the production of microporous materials such as high silicon ZSM-5 zeolite. Tetrapropylammonium hydroxide generally uses tetrapropylammonium halide salt as a raw material. Through electrolysis, tetrapropylammonium cations are combined with hydroxide ions to form tetrapropylammonium hydroxide. Compared with ammonium salts such as tetrapropylammonium chloride, tetrapropylammonium bromide is easy to obtain and has a lower cost. Tetrapropylammonium bromide is generally used as a raw material in the production process of tetrapropylammonium hydroxide. [0003] In view of the above-mentioned related technologies, ...
