用自制的四丙基溴化铵 （ＴＰＡＢｒ） 部分取代四丙基氢氧化铵 （ＴＰＡＯＨ） 为模板剂， 在Ｎａ＋ 离子 （含量２０～３０μｇ／ｇ）存在下， 合成出了结构优良的ＴＳ－１ 分子筛。在丙烯Ｈ２Ｏ２ 氧化制环氧丙烷反应中，考察了合成的ＴＳ－１ 分子筛的催化活性， 催化剂的预处理、用量、利用次数、再生和反应温度与时间对反应的影响。研究表明， 不同的模板剂组成和合成条件明显影响分子筛的晶粒大小。晶粒度为０．４～０．７μｍ 的ＴＳ－１ 分子筛经１０％ ＮＨ４Ａｃ 预处理后， 对丙烯的环氧化具有优良的催化性能。室温下， 用０．４ｇ 催化剂， 以甲醇／水为溶剂， 反应１ｈ， Ｈ２Ｏ２ 转化率和对环氧丙烷的选择性分别可达６５％ ～８０％ ， ８５％ ～９０％ 。
The structure of TS-1 with good structure was synthesized by using tetrapropylammonium bromide (TPABr) partially substituted tetrapropylammonium hydroxide (TPAOH) as templating agent in the presence of Na + ions (content of 20 ~ 30μg / g) Molecular sieve. In the oxidation of propylene oxide to propylene oxide, the effects of the catalytic activity, catalyst pretreatment, dosage, utilization times, regeneration, reaction temperature and reaction time on the reaction of the synthesized TS-1 zeolite were investigated. Studies have shown that different template composition and synthesis conditions significantly affect the molecular sieve grain size. TS-1 zeolite with grain size 0.4-0.7μm has good catalytic performance for the epoxidation of propylene after pretreatment with 10% NH4Ac. At room temperature, with 0.4g catalyst, methanol / water as solvent, the reaction for 1h, H2O2 conversion and selectivity to propylene oxide up to 65% to 80%, 85% to 90%.
