Problems solved by technology

[0005] For the above-mentioned related technologies, the inventors believe that when the concentration temperature is too high, tetrapropylammonium hydroxide is easy to decompose to form impurities, which affects product quality. The concentration temperature is generally not higher than 60°C, and the concentration temperature is low, which affects the production efficiency of high-concentration tetrapropylammonium hydroxide products to a certain extent

Embodiment 1

[0040] Embodiment 1: high-concentration tetrapropyl ammonium hydroxide production process, use electrolyzer to carry out electrolysis, as figure 1 As shown, the electrolytic cell includes an anode chamber 1, a by-product chamber 2, a raw material chamber 3 and a cathode chamber 4 which are successively adjacent at the same height; an anode plate 5 is installed in the anode chamber 1, and a cathode plate 6 is installed in the cathode chamber 4 , the anode plate 5 is connected to the cathode plate 6 through a power supply; the anode chamber 1 communicates with the by-product chamber 2 through the first cationic membrane 7, the by-product chamber 2 communicates with the raw material chamber 3 through the anion membrane 8, and the raw material chamber 3 and The cathode chambers 4 are communicated through the second cationic membrane 9; the production process includes the following steps:

[0041] S1 electrolysis: take tetrapropylammonium bromide, add water to prepare tetrapropylam...

Embodiment 2

[0044] The difference between Example 2 and Example 1 is that step S2 of Example 2 was concentrated in a water bath at 80° C. for 125 minutes without cooling down the concentration process, and the others were consistent with Example 1.

Embodiment 3-6

[0046] The difference between embodiment 3-6 and embodiment 1 is that the process parameters of each step of embodiment 3-6 are different, the circulation flow rate of material in the anode chamber, by-product chamber and cathode chamber is 120ml / min, and others are all kept with embodiment 1 Consistent, each step process parameter of embodiment 3-6 is shown in Table 1.

[0047] Each step technological parameter of table 1 embodiment 3-6

Abstract

The application discloses a high-concentration tetrapropylammonium hydroxide production process and the high-concentration tetrapropylammonium hydroxide prepared therefrom, and relates to the technical field of quaternary ammonium alkali production. The high-concentration tetrapropylammonium hydroxide production process includes the following steps: S1 electrolysis: take tetrapropylammonium quaternary ammonium salt, add water to prepare tetrapropylquaternary ammonium salt aqueous solution, through electrolysis, tetrapropylammonium cation and electrolysis produced Hydroxide ions are combined to form tetrapropylammonium hydroxide to obtain a crude product; S2 concentration: add 0.05-0.2 times the weight of n-propanol to the crude product, mix well to obtain a mixed solution, and heat the mixed solution to 60- Concentrate at 80°C for no less than 60 minutes to produce high-concentration tetrapropylammonium hydroxide. The high-concentration tetrapropylammonium hydroxide production process has the advantage of high production efficiency.

Description

technical field [0001] The application relates to the technical field of quaternary ammonium base production, in particular to a high-concentration tetrapropylammonium hydroxide production process and the high-concentration tetrapropylammonium hydroxide prepared therefrom. Background technique [0002] With the development of society, people's living standards continue to improve, and society's requirements for environmental protection are getting higher and higher. As a porous material with a high specific surface area, molecular sieves are gradually being widely used in the fields of VOC treatment, automobile exhaust purification treatment, and steel plant exhaust gas treatment. The synthesis of molecular sieves generally requires the use of quaternary ammonium bases as templates, and tetrapropylammonium hydroxide as a template for the synthesis of molecular sieves is gradually widely used in the synthesis of all-silicon ZSM-5 molecular sieves, TS-1 molecular sieves and ot...
