Unless reagent grade sucrose is available use cane sugar.

商业用蔗糖有两个主要来源——甜甘蔗和制糖甜菜。

All chemicals from commercial sources were of reagent grade and used without further purification.

所有商业来源的化学药品都是试剂级别的，不经过纯化即可使用。

It is reveal by GC analysis that the purity of the TMP, treated by reduced pressure distillation and recrystallization in acetic ester, approximates to that of the reagent grade TMP.

GC分析结果表明：采用减压蒸馏及乙酸乙酯重结晶并用的方法精制的TMP纯度接近于试剂级TMP。
