1、化工英语词汇Analysis[ə'nælɪsɪs]n.(化合物或混合物的)分解,解析,分析Analyse[ˈænəlaiz]vt.分析,分解,解释fractionation [,frækʃən'eʃən]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。Thetechnologiesandprocessesavailabletomanufacturetheseproductsarebyfractionation,hydrogenationand
2、interesterification.该技术和工艺可以生产这些产品的分馏,加氢和交换。Fermentationrequiredonlyaday,andfractionationwasnotcomplicated.发酵只需要一天,分馏并不复杂。distill [dɪs'tɪl]vt.提取;蒸馏;使滴下vi.蒸馏;滴下;作为精华产生(等于distil)DistillRecycle蒸馏回收Downstreamassetsincluderefineries,whichdistillcrudeintodifferentchemic
3、als,includinggasoline.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。Distillationn.蒸馏,净化;蒸馏法;精华,蒸馏物英[,dɪstɪ'leɪʃn]美[,dɪstl'eʃən]distillationcolumn[化工]分裂蒸馏塔;[化工]蒸馏塔;[化工]蒸馏柱;[化工]精馏塔distillationtower蒸馏塔Hetriedtoobtainanothermaterialbydistillation.他试图通过蒸馏法获得另一种物质。Theymaybepresentin
