㈡ 英语翻译

Reaction procts recovery .
反应产物的回收
Reactor procts are first exchanged to proce steam, then cooled to about 80-90。C, and scrubbed with a 30-35 percent aqueous ammonium sulfate solution with some free sulfuric acid. Here excess ammonia is removed and most of the scrubbed solution recycled. Some sulfuric acid is added and part of the solution withdrawn for ammonium sulfate recovery. The ammonium sulfate solution, for a number of reasons , contains very low organic impurities and after special treatment gives white crystals in conventional equipment.
反应产物先进行（热）交换，产生蒸汽，然后冷却到80－90℃，并用30－35％的含有某些游离硫酸的硫化铵水溶液擦洗。这里将过多的氨去除，而大多数擦洗的溶液则被循环利用。添加一些硫酸，而部分溶液被收回用于硫化铵的回收。由于几个理由，硫化铵溶液含有很少的有机杂质，并在特殊处理后在常规的设备中形成白色的晶体。
Hot gases from the neutralizer next are water washed at ambient temperature to absorb acrylonitrile ,acetonitrile hydrogen cyanide and other by procts . effluent gases ---mainly nitrogen , carbon oxides and unreacted oxygen and propylene-are vented .
来自后面中和器的热气体在室温下水洗，以吸收丙烯腈、乙腈、氰化氢和其他副产物。排放的气体（主要是氮气、二氧化碳和没有反应的氧和丙烯）被放空排出。
This organic solution is steam stripped and crude acrylonitrile recovered as overhead and the lean water recycled from the bottom to the top of the absorption tower .
这一有机溶液是蒸汽气提的，粗丙烯腈作为塔顶馏出物回收，而废水从吸收塔底部到顶部循环。
Small alkali additions are made to this solution to maintain its ph and avoid corrosion problems .
对此溶液添加少量的碱，以保持其pH值，并避免腐蚀问题。
Acylonitrile purification
丙烯腈的提纯
After preliminary evaporation to remove high boiling proce-cyanohydrins and a little succinonitrile-purification of acrylonitrile is carried out by a series of distillation step. Succinonitrile is formed in trace amounts by the addition of HCN to the very small amounts of carbonyl compounds-acrolein ,acetaldehyde , acetone-present in the mixture
在初步蒸发去除高度沸腾的产物氰醇后，通过一系列的蒸馏步骤进行丙烯腈的少量丁二腈提纯。丁二腈是通过将HCN添加进存在于混合物中的很少量的羰基化合物（丙烯醛、乙醛、丙酮）痕量形成的。
Hydrogen cyanide is removed first as overhead at more than 99.5 percent purity and can be recovered and used directly or burned in flare .
氰化氢先作为塔顶馏出物在99.5％的纯度下去除，并可回收和直接采用，或像火炬一样烧掉。
Next , acetonitrile is removed by extractive distillation with water ；minimum of acrylonitrile is lost with the dilute aqueous solution of acetonitrile as bottoms . this solution is stripped in another column not show in fig.1—and the bottoms water recycled to the extractive distillation step . the homogeneous phase containing up to 70 percent acetonitrile at the top may be disposed of or preferable used for recovering very pure , dry acetonitrile
接下来，通过用水的萃取蒸馏去除乙腈；只有最少的丙烯腈随着乙腈的稀释水溶液作为底部残留物损失掉。这一溶液在另一个蒸馏塔（图1中没有示出）中被气提，底部的水循环利用到萃取蒸馏步骤。在顶部含有高达70％乙腈的均相可加以处理，或宁可用于回收很纯的干燥乙腈。
Acrylonitrile is dehydrated and the overhead , an azeotropic mixture of acrylonitrile and water , carries small amounts of low boiling impurities which are essentially the last traces of acrolein.
丙烯腈被脱水，而顶部馏出物（一种丙烯腈和水的共沸混合物）携带了少量的低沸点杂质，它们本质上是丙烯醛的最后痕迹。dehydration column bottoms are fed to the final purification step where pure acrylonitrile goes overhead and the bottom containing some acrylonitrile and the high boiling impurities is recycled to the beginning of the purification process. 脱水塔底部馈送到最后提纯步骤，在那里，纯的丙烯腈到达顶部和含有一些丙烯腈的底部，高沸点的杂质则循环到提纯工艺的起点。

㈤ “苯酚氧化羰基化反应合成碳酸二苯酯”翻译成英文是什么哦

简称DPC

㈥ 化学专业英语，英译汉

臭氧引起的降解
正常情况下，当其他的氧化、老化过程非常慢，聚合物可以在相当长的时期内保持自身的特性，而大气中的臭氧则可诱发聚合物的降解。大气中存在的臭氧，即使很低的浓度，也将显著地加速聚合材料的老化。饱和聚合物的这一过程伴随着大量的含氧化合物的形成,并改变分子的质量、破坏材料的机械和导电性能。暴露在臭氧环境中的聚合物将迅速地相继形成大量含有羰基和基于脂肪脂、酮类和内脂以及带有苯乙烯键的芳香羰基的不饱和羰基产物。此前，随着时间和浓度，逐渐形成更多的醚类、羟基和乙烯基作为终端的产物。臭氧与聚合物产生这些反应，与主链上含有含C C键、苯环或饱和烃键有关。这一反应过程中，双极离子或过氧自由基等不稳定介质能引发异构或降解，从而导致高分子的分解。在这种外部环境的影响下，臭氧的氧化速率和聚合物链上氢原子的转移速率均有所增加。这是由于反应中心的杂化轨道从sp3变到了sp2。聚乙烯醇（PVAL）的乙醇基在臭氧的氧化作用下形成酮基，并依次成为酮烯醇互变异构现象的源头，在臭氧的进一步攻击下导致链无规则断裂，从而产生断链作用。PVAL形成了强大的氢键与臭氧的联合体，其交互作用的能量达到47.3 kJ/mol，可以慢慢通过臭氧的氧化而降解。红外光谱的分析表明，最终产品是低聚物主链上带有大量酮基和羧基作为终端的PVAL低聚物。

㈨ 将下面这段文字翻译成英文。。。在线等。。。急 。。。

Dimethyl carbonate (DMC), an important intermediate for organic synthesis, is widely used in the field of high-performance resins, solvents etc. Compared with phosgene and oxidative carbonylation, the advantages of its transesterification which include the mild reaction conditions, low toxicity and high selectivity, have become the reasons of being focus in the DMC synthesis process. However, there are many drawbacks for catalyst separation and reuse in this reaction system currently. Therefore, looking for a suitable catalyst carrier to enhance catalyst activity and selectivity is significant to approach the DMC synthesis process bottlenecks.
This thesis will introce using higher vitality of methanol and ethylene carbonate (EC) transesterification synthesis to generate DMC. Alkaline-earth metal Mg 后面的太专业了..翻译不出了
