A binary compound of bromine with another element, such as silver .

溴化物由溴和另一元素构成的二元化合物,如银

"Bromide:a binary compound of bromine with another element, such as silver."

溴化物:由溴和另一元素构成的二元化合物,如银。

The reduction of trihalomethane formation potential was discussed, which indicated that ozonation has a good removal for chlorofom and bromodichloromethane formation potential, but for dibromochloromethane formation potential the removal efficiency was undesirable and there was almost no removal for bromoform forming potential, Furthermore, when there was enough bromide in water, ozonation would have a promotion effect for bromoform formation potential.

通过研究臭氧对三卤甲烷生成潜能的去除规律发现,臭氧对三氯甲烷和二氯一溴甲烷生成潜能都有很好的去除,对一氯二溴甲烷生成潜能的去除效果较差,对溴仿生成潜能基本没有去除。当水中溴化物含量较高时臭氧对溴仿的生成反而具有促进作用。

One of the halogens, it is a deep red, fuming liquid at ordinary temperatures (freezing point 19 F [-7.2 C]; boiling point 138 F [59 C]) that contains diatomic molecule s (Br2), and it does not occur free in nature.

是一种卤素,深红色,常温下以发烟液体形式存在(熔点︰-7.2℃〔19℉〕。沸点︰59℃〔138℉〕)。溴的液体和气体分子都含有两个原子(Br2),仅以溴化物形式存在。

The overall yield was 43.6%.The yield of reduce of ester was increased nearly one times than the past method because of KBH4-LiCl as the reducing agent instead of NaBH4. Changing the reaction conditions of bromization, the one-way yield enhanced 30%. The yield of reduce of the bromide was added by one times by improving the process. Tefluthrin was achieved by the catalytic esterification of DCC and DMAP.

优化后工艺对四氟对苯二甲酯的还原采用了廉价高效的还原试剂KBH4-LiCl,使收率比NaBH4法提高了近一倍;对溴化反应条件进行了优化,单程收率提高了30%;对溴化物还原条件的优化,使其收率提高了近一倍;采用了催化剂DCC和DMAP合成了最终产品七氟菊酯。

The bromo-polyethylenegylcol-monomethacrylate was synthesized by two steps. Firstly, methylacrylic acid was esterified with polyethylene glycol (PEG, M=200, 400) to give polyethyleneglycol-monomethacrylate Secondly, treatment of PEG-MA with phosphorus tribromide gave the aim product.

以聚乙二醉(M分别为200,400)和甲基丙烯酸进行单酯化反应,所得单酯再与三溴化磷进行溴化反应合成了一种新的两端具有功能团的不饱和溴化物,即溴代甲基丙烯酸单聚乙二醇酯。

A chemical or chemicals viewed from the perspective of their structural characteristics. Included here are concepts which can mean either a salt, an ion, or a compound (e.g.,"Bromates" and "Bromides").

根据其结构特性划分的一种或一类化学物质,包括某种盐,某种离子或某种化合物,如溴酸盐及溴化物。

Shandong Tianxin Chemical Co., Ltd.(formerly the Shandong Shouguang Salt Chemical Plant)– We are a provincial-level high-tech enterprise specialized in the development and manufacture of bromine series products. And we are the professional production and export base of inorganic bromides in China.

山东天信化工有限公司(原山东省寿光市盐业化工厂):是一专业从事溴系列产品开发生产的省级高新技术生产企业,为国内最大的无机溴化物专业生产出口基地。

In particular, a process for the synthesis of nanopowders of various materials such as metals, alloys, ceramics and composites by induction plasma technology, using organometallic compounds, chlorides, bromides, fluorides, iodides, nitrites, nitrates, oxalates and carbonates as precursors is disclosed.

具体地,公开了一种通过感应等离子体技术合成各种材料,例如金属、合金、陶瓷和复合物的纳米粉末的工艺,使用有机金属化合物、氯化物、溴化物、氟化物、碘化物、亚硝酸盐、硝酸盐、草酸盐、碳酸盐作为前驱体。

Monophenyltin trichloride reacts withdicarbonyl dicyclopentadienyl titanium immediately at room temperature, but no ti-tanium-tin complex produced, and the products were diphenyltin dichloride〓 and tin or stannous Chloride. When diaryltin dihalides were used, only the chlorides and bromides reacted with 〓form the complexes containing titaninm-tin bond,〓. but the corresponding iodide complex was not found. This reaction is Sensitive totemperature,when the temperature is belw 10℃,the reaction hardly takes place,but as the temperature is above 25℃,more 〓 will be found and the reactionbecome more complex.

Ph-SnC〓室温下即可与Cp〓迅速反应,但不生成含钛一锡链的化合物,而是生成Ph〓和Sn或Sn〓二芳基二卤化锡化物中,只有氯化物和溴化物才能和〓反应生成含钛〓锡键的化合物〓相应的碘化物则不行,而且反应对温度比较敏感,低于10℃,反应几乎不能进行,而高于25〓,则会生成更多的〓,在回流条件下得不到含钛〓锡键的化合物,只能得到分解产物,〓和Sn或〓。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
