松节油水合萜二醇合成对(艹孟)烷二胺反应的研究

探索研究了由水合萜二醇制备对(艹孟)烷二胺(MDA)的全新合成路线.使用叠氮化钠将水和萜二醇转化成为二叠氮基对(艹孟)烷(平均得率73.1%),再通过林德拉(Lindlar)催化剂使其催化加氢还原,成功制备了对划出界(艹孟)烷二胺(平均得率86.3%),反应总得率为63.1%.合成对(艹孟)烷二胺产品经过分离和提纯后通过物理性能、气相色谱组成、GC-MS、IR、1H NMR等分析测试,鉴定了化学结构.在此基础上,对(艹孟)烷二胺产品作为环氧树脂固化剂进行了应用试验,其试验结果表明,该合成产品与市售对蓋烷-1,8-二胺产品性能相当.研究结果表明,该合成路线是有效可行的.

Study on Synthesis of p-Menthanediamine from Turpentine Derivative Terpin Hydrate

A new route to synthesize p-menthanediamine(MDA)from terpin hydrate was conducted in the paper,through which di-azido-p-menthane is synthesized at an average yield 73.1 % by reaction between terpin hydrate and sodium azide catalyzed by sulphuric acid followed by hydrogenation catalyzed by Lindlar catalyst to give MDA at an average yield of 86.3 %.The total yield is 63.1 % based on the terpin hydrate.The purified product MDA was analyzed with GC,and its chemical structure was identified through GC-MS,FTIR,1H NMR.Thereafter,the product was applied as a curing agent to prepare an epoxy-resin.Results showed that it has properties similar to the marketed p-menthane-1,8-diamine.The synthetic route was proved to be effective and feasible for the preparation of MDA.
