Curriculum of chemical engineering
As chemical engineering knowledge developed, it was inserted into university courses and curricula. Before World WarⅠ, chemical engineering programs were distinguishable from chemistry programs in that they contained courses in engineering drawing, engineering thermodynamics, mechanics, and hydraulics taken from engineering departments. Shortly after World WarⅠthe first text in unit operations was published. Courses in this area became the core of chemical engineering teaching.
By the mid-1930s, chemical engineering programs included courses in (1) stoichiometry (using material and energy conservation ideas to analyze chemical process steps), (2) chemical processes or “unit operations”, (3) chemical engineering laboratories “in which equipment was operated and tested”, and (4) chemical plant design (in which cost factors were combined with technical elements to arrive at preliminary plant designs). The student was still asked to take the core chemistry courses, including general, analytical, organic, and physical chemistry. However, in addition, he or she took courses in mechanical drawing, engineering mechanics, electric circuits, metallurgy, and thermo-dynamics with other engineers.

1.化学工业的起源
尽管化学品的使用可以追溯到古代文明时代,我们所谓的现代化学工业的发展却是非常近代(才开始的)。可以认为它起源于工业革命其间,大约在1800年,并发展成为为其它工业部门提供化学原料的产业。比如制肥皂所用的碱,棉布生产所用的漂白粉,玻璃制造业所用的硅及Na2CO3. 我们会注意到所有这些都是无机物。有机化学工业的开始是在十九世纪六十年代以William Henry Perkin 发现第一种合成染料—苯胺紫并加以开发利用为标志的。20世纪初,德国花费大量资金用于实用化学方面的重点研究,到1914年,德国的化学工业在世界化学产品市场上占有75%的份额。这要归因于新染料的发现以及硫酸的接触法生产和氨的哈伯生产工艺的发展。而后者需要较大的技术突破使得化学反应第一次可以在非常高的压力条件下进行。这方面所取得的成绩对德国很有帮助。特别是由于1914年第一次世界大仗的爆发,对以氮为基础的化合物的需求飞速增长。这种深刻的改变一直持续到战后(1918-1939)。
1940年以来,化学工业一直以引人注目的速度飞速发展。尽管这种发展的速度近年来已大大减慢。化学工业的发展由于1950年以来石油化学领域的研究和开发大部分在有机化学方面取得。石油化工在60年代和70年代的迅猛发展主要是由于人们对于合成高聚物如聚乙烯、聚丙烯、尼龙、聚脂和环氧树脂的需求巨大增加。
今天的化学工业已经是制造业中有着许多分支的部门,并且在制造业中起着核心的作用。它生产了数千种不同的化学产品,而人们通常只接触到终端产品或消费品。这些产品被购买是因为他们具有某些性质适合(人们)的一些特别的用途,例如,用于盆的不粘涂层或一种杀虫剂。这些化学产品归根到底是由于它们能产生的作用而被购买的。
