有机化合物中碳氢的测定,自1916年 F.普列格尔(Pregl)建立了微量测定的方法迄今四十多年来已有了很大的发展。不论是在样品的分解、燃烧产物的测定,或者是干扰物质的去除和仪器等各方面,都有了很多的改进。整个分析时间也经典法的一小时左右缩短到十几分钟,测定仪器也在向自动化、半自动化方向进展。随着新型有机工业和有机化学的飞速发展,含其他元素(F,P,Si,B,Se,金属)的有机化合物中的碳氢测定也愈来愈受到人们的重视。普列格尔的当年同事 H.李勃(Lieb)曾在1958
The Determination of Hydrocarbons in Organic Compounds Since 1916 the method of establishing trace assays by Pregl has evolved considerably over the past four decades. Whether in the decomposition of the sample, the determination of combustion products, or the removal of interfering substances and equipment, have made many improvements. The whole analysis time is also shortened to about ten minutes by the classical method in an hour or so. Measurement instruments are also moving towards automation and semi-automation. With the rapid development of new organic industry and organic chemistry, the determination of hydrocarbons in organic compounds containing other elements (F, P, Si, B, Se and metals) has drawn more and more attention.
