㈠ 羰基的英文怎麼說

羰基
[詞典] carbonyl (group);

㈡ 英語翻譯

Reaction procts recovery .
反應產物的回收
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 Some sulfuric acid is added and part of the solution withdrawn for ammonium sulfate recovery.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.
反應產物先進行（熱）交換，產生蒸汽，然後冷卻到80－90℃，並用30－35％的含有某些游離硫酸的硫化銨水溶液擦洗。這里將過多的氨去除，而大多數擦洗的溶液則被循環利用。添加一些硫酸，而部分溶液被收回用於硫化銨的回收。由於幾個理由，硫化銨溶液含有很少的有機雜質，並在特殊處理後在常規的設備中形成白色的晶體。
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 .
來自後面中和器的熱氣體在室溫下水洗，以吸收丙烯腈、乙腈、氰化氫和其他副產物。排放的氣體（主要是氮氣、二氧化碳和沒有反應的氧和丙烯）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 .
這一有機溶液是蒸汽氣提的，粗丙烯腈作為塔頂餾出物回收，而廢水從吸收塔底部到頂部循環。
Small alkali additions are made to this solution to maintain its ph and avoid corrosion problems .
對此溶液添加少量的鹼，以保持其pH值，並避免腐蝕問題。
Acylonitrile purification
丙烯腈的提純
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
在初步蒸發去除高度沸騰的產物氰醇後，通過一系列的蒸餾步驟進行丙烯腈的少量丁二腈提純。丁二腈是通過將HCN添加進存在於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 .
氰化氫先作為塔頂餾出物在99.5％的純度下去除，並可回收和直接採用，或像火炬一樣燒掉。
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
接下來，通過用水的萃取蒸餾去除乙腈；只有最少的丙烯腈隨著乙腈的稀釋水溶液作為底部殘留物損失掉。這一溶液在另一個蒸餾塔（圖1中沒有示出）中被氣提，底部的水循環利用到萃取蒸餾步驟。在頂部含有高達70％乙腈的均相可加以處理，或寧可用於回收很純的乾燥乙腈。
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.
丙烯腈被脫水，而頂部餾出物（一種丙烯腈和水的共沸混合物）攜帶了少量的低沸點雜質，它們本質上是丙烯醛的最後痕跡。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. 脫水塔底部饋送到最後提純步驟，在那裡，純的丙烯腈到達頂部和含有一些丙烯腈的底部，高沸點的雜質則循環到提純工藝的起點。

㈤ 「苯酚氧化羰基化反應合成碳酸二苯酯」翻譯成英文是什麼哦

簡稱DPC

㈥ 化學專業英語，英譯漢

臭氧引起的降解
正常情況下，當其他的氧化、老化過程非常慢，聚合物可以在相當長的時期內保持自身的特性，而大氣中的臭氧則可誘發聚合物的降解。大氣中存在的臭氧，即使很低的濃度，也將顯著地加速聚合材料的老化。飽和聚合物的這一過程伴隨著大量的含氧化合物的形成,並改變分子的質量、破壞材料的機械和導電性能。暴露在臭氧環境中的聚合物將迅速地相繼形成大量含有羰基和基於脂肪脂、酮類和內脂以及帶有苯乙烯鍵的芳香羰基的不飽和羰基產物。此前，隨著時間和濃度，逐漸形成更多的醚類、羥基和乙烯基作為終端的產物。臭氧與聚合物產生這些反應，與主鏈上含有含C C鍵、苯環或飽和烴鍵有關。這一反應過程中，雙極離子或過氧自由基等不穩定介質能引發異構或降解，從而導致高分子的分解。在這種外部環境的影響下，臭氧的氧化速率和聚合物鏈上氫原子的轉移速率均有所增加。這是由於反應中心的雜化軌道從sp3變到了sp2。聚乙烯醇（PVAL）的乙醇基在臭氧的氧化作用下形成酮基，並依次成為酮烯醇互變異構現象的源頭，在臭氧的進一步攻擊下導致鏈無規則斷裂，從而產生斷鏈作用。PVAL形成了強大的氫鍵與臭氧的聯合體，其交互作用的能量達到47.3 kJ/mol，可以慢慢通過臭氧的氧化而降解。紅外光譜的分析表明，最終產品是低聚物主鏈上帶有大量酮基和羧基作為終端的PVAL低聚物。

㈨ 將下面這段文字翻譯成英文。。。在線等。。。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 後面的太專業了..翻譯不出了
