[求助] 英译汉几句化学反应的描述

This side reaction is minimized by keeping the
amount of water in the reaction mixture to a
minimum, and also by using a healthy excess of
methylamine. This scheme of things encourages
the 1 to tie itself up with methylamine
to form the Schiff s base, rather than float
around freely in solution where it could be reduced
by the aluminum

保持反应体系中水的量尽可能少或加入过量的甲胺, 就能最大限度抑制该副反应. 这样可使 1 通过与甲胺形成希夫碱被束缚, 而非在溶液中游离并可能被铝还原掉.
