回流萃取英语怎么说及英文翻译

㈠ 85℃水浴加热回流提取2次用英语怎么说

85 C water bath heating, refluxing and extracting for 2 times

㈡ 英语翻译 RT..怎么翻译恰当,“作为萃取物等效于新鲜”么很疑惑.那个"equiv."怎么翻译

整句话的上下文贴上来才知道“怎么翻译恰当?”.你那样翻译不对!as 在这里不应内是作“作为……”解!容
fresh：
在这里是：“n.开始；新生；泛滥”——而你翻译中使用的“新鲜”一词实际上是一个形容词；
如果“equiv.to”做“等于……”解,extract 则也应是名词,而且应与“fresh”一样,同为“抽象名词”； 你翻译成“萃取物”则属于“具体名词”了,在英文里当为复数形式才对.两厢不可能“相等”；
仅从你提供的这点文本字面含义翻译的话,也只能是：“萃取犹如新生”

㈢ 请帮忙翻译成英文,急!!

1.5) The above analysis, welding procts processed colloidal major adverse internal rupture analysis Client proct is in the process of returning welding processing method is flawed, procts without fully warmed by the heat process, allowing a small number of procts subject to greater external vibration (or impact) PCB damage to the procts of colloid and the combination of his appearance. breakdown procts colloidal bad. 1.6) in order to prove the above analysis : reusable packaging similar to the appearance of my Liangpin reservoir simulation procts in the past when the heating temperature SMT machine so heating tests. Heating procts will be on stage heating (heating temperature of Taiwan : 255 ° C), down from about 10 seconds. Colloidal not cooling procts, or indirectly done anything in a positive light procts colloidal external impact. Observer status exterior procts again, The results showed the bottom of colloidal procts (colloidal or indirectly) with a clear separation of PCB material adverse combination Department (Fig9. Fig10 said), providing customers with samples appearance similar situation. Fig9 : bottom of colloidal materials with a clear separation Fig10 : PCB PCB build a separate aspect of colloid and (2) corrective measures to prevent Corrective Action /Prevent Action : 2.1) above analysis, I proposed the use of welding procts in a client to properly handle the security, SMT machine in the course of operations to avoid procts from larger external vibration (or impact) particularly in the finished SMT machine, the heat not yet fully colloidal suspension sclerosis (especially colloidal internal). If the procts subject to vibration (or impact) will be very easy to damage created by the combination of colloidal materials with PCB separation bad. Appearance damage; The direct cause serious internal circuits have access, resulting in unstable procts -- Open or bad. 2.2) recommended clients in completed SMT machine, all alts that were ready to lay the best use of every piece of sponge or bubble paper isolation circuit board. prevent collisions between the PCB and PCB bad vibration friction procts; Canal light possible light up avoid excessive vibration, the effects of colloid and PCB material, and his appearance or the proct unstable.

㈤ 将下面这段文字翻译成英文

甲苯和乙醇都是有机合成中常用的原料，同时也是化工工业中用途非常广的有机溶剂。常压下，甲苯和乙醇会形成共沸混合物，共沸温度为76.9℃，共沸组成中乙醇67.8wt%，常规精馏无法清晰分离。本文采用萃取精馏的方法分离甲苯-乙醇共沸物系，并使用Aspen plus模拟软件进行工艺流程模拟与优化。
首先运用Aspen plus绘制甲苯-乙醇二元物系的气液平衡相图，进行初选萃取剂；采用Flash模块绘制等相对挥发度曲线和残余曲线，选择合适萃取剂并判断其可行性，正丁苯和正丙苯均能有效提高甲苯-乙醇挥发度，达到分离效果。
然后运用Aspen plus对正丁苯和正丙苯作萃取剂分别进行流程模拟，考察了原料和溶剂进料位置、回流比、溶剂进料流率等参数对产品纯度的影响规律，得到合适的操作参数。计算结果表：正丁苯作萃取剂时，萃取精馏塔塔板为20块，萃取剂和原料进料位置分别为第8块和第19块，回流比为1.1，溶剂进料流量为220kg/hr；溶剂回收塔塔板为24块，进料位置为第8块，回流比为2.4，甲苯和乙醇产品的质量分数都达到了99.9%。正丙苯作萃取剂时，萃取精馏塔塔板为35块，萃取剂和原料进料位置分别为第16块和第32块，回流比为2.4，溶剂进料流量为220kg/hr；溶剂回收塔塔板为30块，进料位置为第12块，回流比为4.8，甲苯和乙醇产品的质量分数都达到了99.9%。
最后对两种萃取剂的能耗和经济性进行对比，正丁苯作萃取剂更适合分离甲苯-乙醇共沸物系。
Toluene and ethanol are commonly used in organic synthesis of raw materials, but also the chemical instry is widely used in organic solvents. Under normal pressure, toluene and ethanol will form an azeotropic mixture, azeotropic temperature of 76.9 ℃, azeotropic composition of ethanol 67.8wt%, conventional distillation can not be clearly separated. In this paper, toluene - ethanol azeotrope was separated by extractive distillation and the process flow was simulated and optimized using Aspen plus simulation software.
Firstly, the gas - liquid equilibrium phase diagram of toluene - ethanol binary system was used to extract the initial extraction agent. The relative volatility curve and resial curve were drawn by Flash mole, and the appropriate extraction agent was selected and its feasibility was determined. Benzene and n-propylbenzene can effectively improve the toluene - ethanol volatility, to achieve separation effect.
The effects of parameters such as raw material and solvent feed position, reflux ratio and solvent feed rate on the purity of the proct were investigated by using Aspen plus for the extraction of n-butylbenzene and n-propylbenzene as extraction agents. The appropriate operating parameters The Calculated results table: n-butyl benzene as extractant, extractive distillation tower tray 20, extractant and raw material feed position were 8 and 19, the reflux ratio of 1.1, the solvent feed flow of 220kg / Hr; solvent recovery tower for the 24, the feed position for the first eight, the reflux ratio of 2.4, toluene and ethanol procts have reached 99.9% of the mass fraction. When the extraction agent is used as the extractant, the extractive distillation column is 35, the extraction agent and the raw material feed position are 16th and 32th respectively, the reflux ratio is 2.4, the solvent feed flow is 220kg / hr, the solvent Recycling tower plate for the 30, the feed position for the first 12, the reflux ratio of 4.8, toluene and ethanol procts have reached 99.9% of the mass fraction.
Finally, the energy consumption and economy of the two extractants were compared, and n-butylbenzene was more suitable for the separation of toluene-ethanol azeotrope.
