报导了用UV法和NMR法共同测量丙烯腈与某些芳烃的分子配合常数,以Rose-Drago方程处理数据.并比较了二种方法测定得到的配位常数.结果表明UV法和NMR法测量所得相关系数都很高,大都在0.99以上,认为体系以1:1形式配位的假设是合理的,两种方法得到的配位常数的误差也大体相当.

By means of the same type of Rose-Drago equation, the 1:1 mol. complex equilibrium constants of acrylonitrile with some aromatic donors, namely, benzene, toluene, ethylbenzene, xylenes, mesitylenes and styrene have been measured by UV/Vis and NMR spectroscopic techniques. It has been found that the complex constants determine by these two methods are reasonablely in agreement.
