放热反应;
The change of adiabatic temperature was small during coupling isomerization with aromatization of hexene-1, because both reaction heats were counteracted each other, exothermal reaction for the former and endothermic reaction for the latter.
异构化为放热反应,而芳构化为吸热过程,通过该偶合反应可使反应的绝热温度变化幅度变小,使反应容易控制和操作。
The hydroxylation of phenol to produce dihydric phenol is a rapid and strongly exothermal reaction, the activity of the complex-oxide catalyst decreased rapidly.
苯酚直接羟化制备苯二酚为液固相的强放热快反应,催化剂的活性衰减很快。
It shows that this reaction is an exothermal process.
测得萃取反应的焓变及热力学函数均为负值,表明该萃取反应是放热过程。
