STUDY ON THE SYNTHESIS AND APPLICATION OF ENVIRONMENTALLY FRIENDLY CATALYST TS 1 ZEOLITE

针对具有应用前景的新型环境友好氧化催化剂 Ｔ Ｓ１ 合成中存在的问题，采用新方法合成 Ｔ Ｓ１ 分子筛，显著改善和提高了 Ｔ Ｓ１ 分子筛的氧化反应性能，解决了 Ｔ Ｓ１ 分子筛合成难以重复以及反应活性不易稳定的问题。在 ２ ０００ ｍ Ｌ 规模 Ｔ Ｓ１ 分子筛合成放大试验研究中，所得 Ｔ Ｓ１分子筛与传统法合成相比，苯酚羟基化反应诱导期缩短一半，活性提高 １ 倍以上，苯酚转化率达到 ２０％ ～２３％ ；用于环己烷氧化生成环己酮反应，环己烷的转化率达 ４９．６％ ；用于环己酮的氨氧化，环己酮的转化率为 ９６％ ～９９％ ；用于丙烯环氧化，转化率为 ９５％ ～９８％ 。

In order to solve the existent problem in synthesizing the new type environmentally friendly catalyst TS 1 zeolite, a new process was developed. The new process increases the oxidation activity of TS 1 zeolite, also improves the activity stability, and solves the synthesis repeatability. The synthesis process was carried on a 2 000 mL vessel. In comparison with the traditional synthesis, the revulsive period of phenol hydroxylation reaction was shortened one half; the activity was double, and the phenol conversion reached 20% to 30%. The conversions of hexane oxidation to cyclohexanone, cyclohexanone oxidation, and propylene oxidation to propylene epoxide were 49.6%, 96%~99% and 95%~98% respectively.
