近期7友们在微信后台留言踊跃，有的7友想了解关于化工常用英语方面的知识。小7特为大家搜集了一些，共分3期推送在每天的微信内容中，请大家留意！今天小7带来的是化工企业生产过程中遇到的部分英语词汇。

analyse [??n?laiz]
vt. 分析，分解，解释
fractionation [,fr?k??n'e??n]
n. 分别；分馏法
蒸馏（Distillation）和分馏（Fractionation）是分离、提纯有机化合物最重要最常用的方法之一。
例句：
1）The technologies and processes available to manufacture these products are by fractionation, hydrogenation and interesterification .
该技术和工艺可以生产这些产品的分馏，加氢和交换。
2）Fermentation required only a day, and fractionation was not complicated.
发酵只需要一天，分馏并不复杂。
distill [d?s't?l]
vt. 提取；蒸馏；使滴下
vi. 蒸馏；滴下；作为精华产生（等于distil）
distill recycle 蒸馏回收
例句：
Downstream assets include refineries, which distill crude into different chemicals, including gasoline.
下游资产通常包括炼油厂，即从原油中提取出不同的化工产品，比如汽油。
distillation [,d?st?'le??n]
n. 蒸馏，净化；蒸馏法；精华，蒸馏物
distillation column
分裂蒸馏塔；蒸馏塔；蒸馏柱；精馏塔
distillation tower
蒸馏塔
例句：
1）He tried to obtain another material by distillation.
他试图通过蒸馏法获得另一种物质。
2）They may be present in the virgin petroleum and as such, are isolated by physical methods, such as distillation or solvent extraction.
这些原料物质，也许本身就存在于原油当中，因此通过物理方法加以分离，如蒸馏和溶取。
3）I've always thought distillation, rather than filtering, was the best water purification method and that distilled water is best for drinking.
我一直认为，比起过滤，蒸馏是净化水最好的方式，而蒸馏水是最好的饮用水。
4）For example, distillation processes that separate out any dissolved minerals by boiling and condensing water require costly amounts of fuel.
例如，蒸馏过程是通过把海水煮沸，使水汽冷凝，将一切溶解矿物质分离出来，这一过程需要大量的燃料。
5）Thermal distillation involves heat: Boiling water turns it into vapor—leaving the salt behind—that is collected and condensed back into water by cooling it down.
热蒸馏涉及到加热：沸腾的水变成水蒸气 ---盐分留了下来 ---被收集的蒸汽冷却后凝结成水。
6）All sorts of chemical processes. Distillation, for example, takes advantage of the properties of liquid and gas mixtures.
所有各种化学过程，比如蒸馏，就利用了液相,和气相的混合物。
decoloration [,di:k?l?'rei??n]
n. decolor的变形 去色，漂白，消色
decolor [di:'k?l?]
vt. [美国英语] =decolour 脱色，漂白
例句：
1）The preparation process consists of pretreatment , acid hydrolysis, neutralization , decoloration and concentration.
其制备工艺包括原料的预处理、酸水解、中和、脱色和浓缩。
2）The yield of monoammonium glycyrrhizinate was 1.30% and content was 95% by the lixiviation, ammoniation, acidation, decoloration and recrystal.
经过浸提、氨化、酸化、脱色、重结晶过程可得到含量为95%的甘草酸铵，甘草酸铵的最终提取率为1.30%。
3）The decoloration of Reactive Brilliant Red X-3B in Aeration/UV system with Activated Carbon as catalyst was studied, and preliminary analysis about the mechanism of catalysis was done.
本文采用以活性炭作催化剂的曝气/紫外光体系，对染料活性艳红X- 3B的光氧化脱色进行了试验。
