摘要

含有亚甲基（- CH2 -）并与-NO2、-COCH3等吸电子基团直接成键的化合物称为活性亚甲基化合物。亚甲基具有活性和酸性。这些化合物可以发生互变异构，形成酸。具体和最简单的例子是硝基甲烷。硝基甲烷发生1,3−异位异构反应，生成硝基甲烷的异构体（CH3-NO2 + CH2NO2H）。在目前的工作中，我们试图计算硝基甲烷互变异构体混合物中硝基仿和棒状仿的百分比组成，使用了一种有75年历史的工具，称为折射器(F)。

Estimation of the composition of nitro-aci forms of nitromethane tautomerism by refrachor (F) an old tool for a new contemporary observation

Compounds containing methylene group (−CH₂−) and bonded directly to electron withdrawing groups such as –NO₂ and –COCH₃ etc., are called active methylene compounds. The methylene group is active and acidic. These compounds can undergo tautomerism giving acid form. The specific and simplest example is nitromethane. Nitromethane undergoes 1,3−protropy tautomerism giving rise to aciform of nitromethane (CH₃–NO₂

⇌

CH₂NO₂H). In the present work we have tried to calculate the percentage composition of the nitroform and the aciform in the tautomeric mixture of nitromethane using a seventy-five-year-old tool called the refrachor (F).
