Since H〓S and SO〓 adsorbed on TiO〓 could react with each other and TiO〓 is the medium of their electron transfer, thus SO〓 could not be adsorbed quite strong on the active site of TiO〓, which makes it more resistant to sulfating and increase the stability of catalyst. Finally, the model and mechanism of the reduction of SO〓 by NH〓 to elemental sulfur is advanced as follows: on the sulfide catalyst, ammonia is decomposed to N〓 and H〓, and H〓 reacts with SO〓 to form the intermedium of H〓S; then H〓S and SO〓 react as Claus reaction on TiO〓 catalyst.

反应系统中过量水蒸气的存在使催化剂表面某些活性位被水蒸气抑制使活性和选择性有较大幅度降低,但这种影响是可逆的,不会造成催化剂永久性中毒;另外当单质硫和水蒸气同时存在时,在〓催化剂上能够生成硫化氢和二氧化硫,而且由于硫化氢和二氧化硫化学吸附能力不同而导致它们的脱附顺序不同,硫化氢的生成温度总是低于二氧化硫的生成温度,说明过量水蒸气的存在会导致氧化物催化剂上逆克劳斯反应的发生;而在硫化物催化剂上几乎没有硫化氢和二氧化硫生成,说明硫化物催化剂能够抑制逆克劳斯反应的发生。

Besides, n-butyl and sec-butyl tosylate that are difficult for oxidative addition can react with phenylmagnesium bromide to form corresponding cross-coupling products. Primary alkyl halide which contains β-hydrogen and is relatively hard to undergo the reaction , n-butyl chloride for instance, can react with aryl Grignard reagents in the presence of NiB alloy as well.

此外,难以进行氧化加成的对甲苯磺酸正丁酯和对甲苯磺酸仲丁酯可以与苯基溴化镁作用生成相应的交叉偶联产物;反应相对困难的含β-H的伯卤烷,如:正氯丁烷也可以在NiB催化下与芳基格氏试剂发生偶联。

But here is the odd thing: blinded trials have shown that MCS patients do not actually react to chemicals, but they do react in unblinded tests when they believe they are being exposed to a trigger.

但奇怪的是:盲试验显示,多发性化学物质过敏症患者实际上对化学品没有反应,但是他们在非盲性的测试中有反应,并相信受到了一系列的影响。

S extract had an inhibition effect against Sphaerotheca fuligenea,The inhibition rate was 100% when extract concentration was 20mg/mL and the inhibition rate got to 67.66% even at the concentration of 2.5mg/mL. The extract of E. humifusa had different preventive effects against four strains of S. fuliginea from four districts in Shanghai. The preventive effects on the Qibao and Baoshan were better than those of Nanhui and Qingpu.
