一、补充教材类实验题有机实验中有一大类是制备实验,但因反应速率过慢、反应物有毒等实际因素,教材中省略了这些实验,如甲烷、溴苯、硝基苯等的制备实验,但这些却是高考常见的命题素材之一。例12005年11月13日,中石油吉林石化公司双苯厂苯胺车间发生爆炸事故,流入松花江的硝基 A. Supplementary Teaching Materials There is a large class of experimental experiments in organic experiments. However, due to the fact that the reaction rate is too slow and the reactants are toxic and other practical factors, these experiments are omitted from the textbooks, such as the preparation of methane, bromobenzene, nitrobenzene, etc. Experiments, but these are one of the common propositions in the college entrance examination. Example 1 On November 13, 2005, an explosion accident occurred in the aniline plant of the Sinopec Jilin Petrochemical Company’s Shuangbang Factory and the nitro that was flowing into the Songhua River.
