Especially , the rearrangement reaction of converting styrene oxide to phenylacetyldehyde were investigated. In this paper, we also studied the method of preparing SO42-/TiO2 by vitriolic titanium boiling regurgitant hydrolyzation and applications of SO42-/TiO2 in the preparation of iso-amyl acetate.

对环氧苯乙烷经分子重排反应制备苯乙醛进行了深入研究；本论文还用硫酸钛沸腾回流水解法制备了纳米SO_4~(2-)/TiO_2固体超强酸粉末，并应用于冰乙酸与异戊醇酯化合成乙酸异戊酯的反应。

Study on technics of synthesize dimethyl fumaricate, firstly prefabricated fumaric acid, with furfural as raw material, V2O5 as catalyst and potassium chlorate as oxidizer then synthesized dimethyl fumaricate through esterication of fumaric acid and methanol with phosphor tungstenic acid as catalyst.

研究了以糠醛为原料，V2O5作催化剂，用氯酸钾氧化制取富马酸，然后以磷钨酸为催化剂，用甲醇进行酯化合成富马酸二甲酯的合成工艺。

However, the chemistry of some carbon compounds such as carbon dioxide and carbonates is regarded as inorganic chemistry.

但是碳的化合物象二氧化碳和碳酸盐还属于无机化学。

The results showed that the heat of synthesis reaction is affected by Al content, heat rate, powder size, compacts density and so on.

结果表明化合反应是一种放热反应，放热量受Al含量、加热速度、粉末颗粒尺寸、压制密度等因素的影响。

Aminobenzothiazoleswere diazotized and then coupled with active methylenecompounds to form a kinds of new hydrazones.

苯基硫脲在浓硫酸中，先在溴作用下氧化合环，再直接硝化，得到产率95％，纯度98％的2-氨基-6-硝基苯并噻唑。

It may be prudent to follow the same approach of our Canadian colleagues of discontinuing combination products until more investigations are available.

我们可以谨慎地仿效加拿大同行在更多研究有效之前停止化合产品的相同做法。

It's -It's a raw iron made from iron and coke.

它是由铁和焦炭化合而成的

The historical evidence, I think, is persuasive enough for one to wonder whether an ideal of unity undifferentiated between cultural ecumenism and political oneness is at all attainable or even desirable.

我想历史能让人思索：一个不分文化合一和政治合一的统一理想是否可得，是否值得？

But because of the acrylic sphere, they can't go as deep as the MIRs.

但也由于驾驶舱的化合球面使其无法潜得像实验艇那么深

The effects of solvent type,concentration of the aqueous ammonia on the yields of target compounds were studied. The different results between 2,6-diamino-3,5-dinitropyridine (and 2,6-diamino-3,5-dinitropyridine-1-oxide) and 3-nitropyridien were analyzed.

探讨了溶剂类型、氨水浓度等反应条件对目标化合物产率影响，并讨论了2，6-二氨基-3，5-二硝基吡啶(2，6-二氨基-3，5-二硝基吡啶-1-氧化物)氧化胺化反应结果与3-硝基吡啶不同的原因。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
