酸酐

Raw material respect: This week suffers the effect that crude oil, naphtha rises in price, market confidence restores, oil is moved on benzene price; Crude benzole suffers the cooking factory reduction of output, effect that is restricted to produce, output falls, crude benzole price rises considerably and supply of goods is nervous, follow closely of cooking benzene market rises, but suitable anhydride manufacturer receives goods apiration to lose a bit.

原料方面：本周受原油、石脑油价格上涨的影响，市场信心恢复，石油苯价格上调；粗苯受焦化厂减产、限产的影响，产量下降，粗苯价格大幅上升且货源紧张，焦化苯市场紧跟上涨，但偏苯三酸酐厂家接货意愿稍弱。

House of benzene of raw material cooking does not fall high, the part arranges anhydride manufacturer to begin pair of oil benzene and hydrogenation benzene inquiry, jie is pressed with be being applied to cooking benzene manufacturer, however crude benzole goods tightens valence firm, bring about cooking benzene airborne possibility is inferior.

原料焦化苯居高不下，部分偏苯三酸酐厂家开始对石油苯及加氢苯询价，藉以对焦化苯厂家施压，然而粗苯货紧价坚，导致焦化苯空降可能性较低。

Of friendly chemical industry of Shanxi live abroad new technology machines 160 thousand tons / year crude benzole mixes 100 thousand tons / year device of the combination that arrange anhydride, first phase 80 thousand tons / year crude benzole refines device already came true to cast makings production success.

生意社8月27日讯 8月25日，CCIN记者在山西省忻州市忻府区煤化工循环经济园区采访时看到，山西侨友化工股份有限公司环保型新工艺加工16万吨/年粗苯和10万吨/年偏苯三酸酐联合装置，一期8万吨/年粗苯精制装置已实现了一次投料生产成功。

The main products are sodium bichromate, chromium hydroxide,chromic anhydride, chrome oxide green, basic chrome sulfate , potassium dichromate etc. Tested by the authoritative organization, all the products meet with the standard of GB.

主导产品有重铬酸钠、铬酸酐、氧化铬绿、碱式硫酸铬、氢氧化铬等，产品经国家化学产品监督检验部门年检、统检、抽检，均优于国家标准规定的优级品、一级品、合格品质量等级指标。

The benzene (or 80% of the butene) and the excess air in a fluidized bed or fixed-bed reactor for oxidation reaction of maleic anhydride was absorbed into the cycle of acid maleic acid.

将苯（或80%的丁烯）与过量空气在流化床或固定床反应器中进行氧化反应生成顺丁烯二酸酐，被循环的酸液吸收成顺丁烯二酸。

Moreover, we found that N-heterocyclic carbene could served as an efficient and novel catalyst for the reactions of aziridines with silylated nucleophiles or acid anhydrides.

随后，我们发现氮杂环卡宾也可以作为一种有机小分子催化剂，分别催化各类硅试剂或酸酐对氮杂环丙烷化合物的开环。

Enzyme like carbonic anhydrase is necessary to speed up the process of carbon conversion.

例如在贝壳中含有碳酸酐酶，其主要作用就是加速碳的转换。

The researchers added carbonic anhydrase genes to plants that do not react to higher levels of carbon dioxide.

研究人员将碳酸酐酶基因的植物，不作出反应的二氧化碳水平较高。

Objective To study the effects of carbonic anhydrase Ⅱ produced by osteoclasts on bone resorption process.

目的：研究破骨细胞分泌的Ⅱ型碳酸酐酶对骨吸收过程的影响。

An assay for carbonic anhydrase enzyme, which is thought to play an important role in the process of bio-calcification revealed novel activity.

在对生物钙化过程中起重要作用的碳酸酐酶的分析中显示了此酶的新颖的活性。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
