Abstract
The invention relates to gemini quaternary ammonium salt or a quaternary ammonium salt compound and a preparation method. The technical problems that a template existing in the prior art is poor in framework rigidity and poor in guidance quality are mainly solved. According to the technical scheme, gemini quaternary ammonium salt or the quaternary ammonium salt compound is adopted, and the structure is shown as the following structure general formula, wherein R1 is alkyl of C1-C10, R2 is at least one of H, halogen and alkyl of C1-C6, and X is any one of chlorine, bromine, iodine and hydroxyl, and the problem is solved well. Gemini quaternary ammonium salt or the quaternary ammonium salt compound is high in structural rigidity and can serve as a template to be used for synthesis of a zeolite molecular sieve. The general formula is shown in the specification.
Description
technical field [0001] The invention relates to a gemini quaternary ammonium salt or quaternary ammonium base compound and a preparation method. Background technique [0002] Quaternary ammonium salts, also known as 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, which are obtained when halogen anions are exchanged for hydroxide ions Molecules are called quaternary amine bases. [0003] Quaternary ammonium salt molecules have many uses, and generally can be 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 ...
