查询词典 sulfur chloride

Liquid-phase epoxidation of allyl chloride with hydrogen peroxide was carried out over Ti-MWW, a novel titanosilicate with the MWW structure, to synthesize epichiorohydrin selectively and effectively. Ti-MWW proved to be superior to the conventional TS-1 catalyst in both catalytic activity and product selectivity. Ti-MWW prefers aprotic solvents of acetone and acetonitrile, both of which can restrain the solvolysis of epichiorohydrin, whereas TS-1 favors a protic solvent of methanol.

研究了具有MWW结构的新一代钛硅分子筛Ti-MWW催化剂对烯丙基氯液相环氧化高效合成环氧氯丙烷的催化性能结果表明，Ti-MWW的催化活性以及产物选择性均优于传统的钛硅分子筛TS-1，对于Ti-MWW，合适的溶剂为非质子性溶剂丙酮和乙腈，在该溶剂中环氧化物不易发生溶剂化开环反应；而对于TS-1，合适的溶剂是质子性溶剂甲醇，但甲醇可导致醇醚副产物的生成。

II: ① take a thin wire, one end with sand paper wipe, and then lightson alcohol to non-yellow flame ignition,② wire with the end of the water dip, and then dip a number of sodium chloride or anhydrous sodium carbonate powder,③ ignited a new spirit lamp (lamp wick is clean, pure ethanol),④ the stained sodium salt powder on the wire on the ignitiontip, when there is a sharpsmall yellow flame, which is sodium flame.

方法二：①取一条细铁丝，一端用砂纸擦净，再在酒精灯外焰上灼烧至无黄色火焰，②用该端铁丝沾一下水，再沾一些氯化钠或无水碳酸钠粉末，③点燃一盏新的酒精灯，④把沾有钠盐粉末的铁丝放在外焰尖上灼烧，这时外焰尖上有一个小的黄色火焰，那就是钠焰。
