用半微量法进行分析化学的实验是贯用的方法。在无机化学中也有采用这种方法进行实验的。然而,对于有机化学来说,如何采用半微量法来进行学生的实验则探讨甚少。目前,国外有人提倡用半微量法进行中学有机化学的学生实验。他们经过实践认为,用半微量法进行中学有机化学的学生实验对于缺乏试剂和仪器的农村中学具有很大的价值。例如:(一)可缩减试剂费20～30倍;(二)可以降低许多有挥发性的、有毒的有机物质对空气的污
Analytical chemistry experiments using semi-trace methods are common. Inorganic chemistry has also been used in this experiment. However, for organic chemistry, there are few studies on how to use semi-trace method to carry out experiments on students. At present, some people abroad advocate the use of semi-micro-organic chemistry experiments in secondary school students. They have practiced that using semi-trace method for organic chemistry experiments in secondary schools is of great value to rural secondary schools that lack reagents and instruments. For example: (A) can reduce the reagent costs 20 to 30 times; (B) can reduce the number of volatile, toxic organic substances on the air pollution
