还是设法将氨气排出反应釜吧。这个更简单。

through a water acid (1 M HNO3)solution kept at 275 K.The trapped ammonia was determined by excess acid titration that allowed to monitor the reaction and evaluate the degree of advancement.
好像没 ...

不能排出，因为是高温反应物也变为气态，会一起被排出的

你的反应物是否和氨气在沸点上存在差异，如果差异较大，可以在反应釜上加一根精馏柱，在合适的温度时，可以使排除的气体绝大部分为氨气，而反应物回流到釜内。

我们这里就是这样进行试验，你可以考虑试 ...
