查询词典 optimal

The aluminum hydrolysis process has been investigated using chemical analysis as the main testing method, we discovered that temperature plays an important part in the formation of products and its properties, at the same time, the change of reaction with the change of temperature is a reversible process. The experiment further proved that the optimal formation temperature of AlCl3·4Al3·7.5H2O and AlCl3·7Al3·18H2O is 75℃,the productivity rate of products were higher at this temperature and the crystallizability were better.
