摘要
在不同温度和酸度时 ,利用滴定微量量热法测定了伯胺N192 3 氯仿液萃取盐酸的振荡反应体系的热功率 -时间曲线 ,根据获得的振荡诱导期 (tin) ,,第一振荡周期 (tp.l)的数据 ,计算了表现活化能和反应级数 ,建立了下列关系式 :tin∝c0 14 72 exp(1 3 48.6T ) tp .1∝c0 2 413 exp(4 3 3 1 .4T )
The power-time curves of the extraction oscillation system were determined at different temperatures for the extraction of hydrochloric acid with primary amine N 1923 in chloroform,using the titration microcalorimetric method.The apparent activation energy and reaction orders were calculated,from the induction period( t in ) and the first oscillation period ( t p.l ) The following relationship were established: t in∝ c 0.1472 exp(1348.6 T ), t p.1∝ c 0.2413 exp(4331.4 T ).
