在1949年中国人民获得解放的时候,由于帝国主义和国内反动统治阶级的多年多种的束缚与摧残,中国化学研究工作的队伍,和其他科学一样,是极其微弱的。在从本世纪二十年代开始一直到解放前,中国化学家一直处在非常艰难的条件之下;三十年间较著称的工作仅有侯德榜关于苏尔维法制碱工艺的研究,庄长恭关于甾族脂环化合物的研究,赵承嘏关于延胡索、麻黄素等药用植物的研究等寥寥可数的工作。1949—1950年中国人民接收的旧中国化学研究机构仅有三个,其中最大的上海中央研究院化学研究所共有工作
When the Chinese people were liberated in 1949, the ranks of Chinese chemical research work, like those in other sciences, were extremely weak due to many years of restraint and destruction by the imperialists and the domestic reactionary ruling classes. Chinese chemists have been under very difficult conditions until the liberation from the 1920s; the more well-known work in the past 30 years was Hou Debang’s research on the legal process of the Survival process, Zhuang Changgong’s work on steroids Research on alicyclic compounds, Zhao Chengtao few on the research of corydalis, ephedrine and other medicinal plants. From 1949 to 1950, the Chinese people received only three old Chinese chemical research institutes, of which the largest Institute of Chemistry, Shanghai Academia Sinica had a total of work
