一种合成间苯三酚的新方法

A New Method of Synthesis of 1, 3, 5-phloroglucin

以三甲氧基苯为原料,经浓盐酸水解制得间苯三酚,收率80%以上。将制备合成的样品进行红外光谱(IR)、紫外光谱(UV)、核磁共振谱(NMR)、质谱(MS)的测定,并进行了解析,结果符合本品的化学结构。该工艺线路具有原料易得,合成路线短,制备方法简便,收率较高,成本较低,三废少等特点。

With trimethoxy benzene as material, after hydrolysis with concentrated hydrochloric acid, prepared phloroglucin, the yield reached 80%. The process route has the feature of easy material obtaining, short synthesis route, preparing method simpleness,high yield, low cost and few three wastes. Tested and analysed the sample with IR,UV,NMR and MS,the results showed the product is consistent with the chemical structure of the substance.
