Synthesis method of MWW molecular sieve

The invention provides a method for synthesizing an MWW molecular sieve by using double template agents, and belongs to the technical field of molecular sieve synthesis, and the method specifically comprises the following steps: taking triethylene diamine and piperazine as the double template agents, taking a silicon source, an aluminum source, boric acid, sodium hydroxide and deionized water as raw materials, mixing to prepare reactant gel, and carrying out hydrothermal crystallization to obtain a crystallized molecular sieve. According to the method, a template agent related to an original synthesis system is broken through, the silica-alumina ratio can be adjusted by adjusting the proportion of the template agent and the content of the structural additive, the toxicity in the synthesis process is low, the synthesis cost is lower, and the product purity is high. 本发明提供了一种利用双模板剂合成MWW分子筛的方法，属于分子筛合成技术领域，具体包括以下步骤：以三乙烯二胺和哌嗪作为双模板剂，硅源、铝源、硼酸、氢氧化钠和去离子水为原料，混合后制得反应物凝胶，再水热晶化得到结晶分子筛。本方法突破了原有合成体系所涉及的模板剂，可通过调节模板剂比例以及结构助剂的含
