Example Embodiment

[0027] [Example 1]

[0028]

[0029] After dissolving 5.28 g of 1,4-p-dibenzyl bromide in 100 ml of ethanol, add 10.8 g of N,N-dimethylbenzylamine, stir at room temperature for 8 hours, stop the reaction and filter, and then use 20 ml of ethyl acetate for the filter cake , 15 ml of ether was washed three times to obtain 10.4 g of Gemini quaternary ammonium salt 1. 1 H NMR(400MHz, DMSO-D 6 )δ7.73-7.53(m,14H), 4.71(s,8H), 2.93(s,12H).

Example Embodiment

[0030] [Example 2]

[0031]

[0032] After dissolving 4.19 g of 2-chloro-1,4-p-dibenzyl chloride in 60 ml of ethanol, add 10.8 g of N,N-dimethylbenzylamine, raise the temperature to 60°C, stir for 20 hours, stop the reaction, filter, and filter cake It was washed with 20 ml of ethyl acetate and 20 ml of ether three times successively to obtain 8.44 g of Gemini quaternary ammonium salt 2. 1 H NMR(400MHz, DMSO-D 6 )δ7.70-7.51(m,13H), 4.70(s,8H), 2.91(s,12H).

Example Embodiment

[0033] [Example 3]

[0034]

Abstract

The invention relates to a gemini quaternary ammonium salt or quaternary amine alkali compound and a synthetic method. The technical problems that a template is poor in skeleton rigidity and guide performance in the prior art are mainly solved. By adopting the technical scheme that the structure of the gemini quaternary ammonium salt or quaternary amine alkali compound is shown as the following general molecular formula(please see the specifications for the general molecular formula), wherein R1 and R2 are alkyl of C1-C6, R3 and R4 are at least one of H, halogen and alkyl of C1-C6, and X is any one of chlorine, bromine, iodine and hydroxyl, the problems are well solved. The gemini quaternary ammonium salt or quaternary amine alkali compound is high in structure rigidity, and can serve as a template used for synthesis of a zeolite molecular sieve.

Description

technical field [0001] The invention relates to a gemini quaternary ammonium salt or quaternary ammonium base compound and a synthesis method thereof. Background technique [0002] Quaternary ammonium salts are compounds in which all four hydrogen atoms of ammonium ions are replaced by alkyl groups. Most of the anion groups are halogen anions. When the halogen anions are exchanged for hydroxide ions, the molecules obtained are called quaternary ammonium bases. . [0003] Quaternary ammonium salt molecules have rich industrial applications and are widely used as: bactericidal disinfectant, soft antistatic agent, flocculant, demulsifier, drag reducer, thickener, anionic synergist, etc. Quaternary ammonium salts that exist in nature generally have biological activity, and some quaternary ammonium salts can be used as phase transfer catalysts for medicinal purposes, pesticides, and chemical reactions. Quaternary ammonium salts are a broad class of cationic surfactants. It has...
