quench是冷却的意思。因为从上下文来看,这个反应还没有结束:
An additional 2 hours of stirring resulted in the reaction reaching -90% completion. To quench, the reaction mixture was removed from heat and allowed to cool to ambient. With stirring, MTBE (2 ml_) was added followed by water (1 ml_). ……
PS.这里的90% completion不是指这一步反应完成了90%,而是指整个工艺已经完成了90%。
我们一直强调求助时要给出上下文,否则一个词可以有多种意思,很不明确。
