Solvent-free tebuconazole synthesis method

The invention discloses a solvent-free tebuconazole synthesis method which comprises the following steps: step 1, adding 1, 2, 4-triazole, a basic catalyst and a phase transfer catalyst into a reaction flask, heating until the mixture is molten, dropwise adding pentane epoxy under a solvent-free condition, and carrying out heat preservation reaction after addition; and 2, after the reaction is finished, stirring and cooling to obtain a solid, and carrying out post-treatment to obtain a tebuconazole finished product. According to the solvent-free tebuconazole synthesis method provided by the invention, tebuconazole is directly synthesized under a solvent-free condition. Compared with a traditional synthesis method, the method does not need a solvent, is greener in process, relieves the environmental protection pressure, is simple in reaction condition, and is suitable for industrial large-scale production. 本发明公开了一种无溶剂的戊唑醇合成方法，包括如下步骤：步骤一，在反应瓶中加入1,2,4-三氮唑、碱性催化剂和相转移催化剂，加热至熔融，在无溶剂条件下滴加戊环氧，加毕保温反应；步骤二，反应结束后，搅拌降温冷却后得
