use
As an analytical reagent, it is also used in organic synthesis
Method 1
1.? The methylamine solution was added to the chemical pure hydrochloric acid under cooling, adjusted to ph = 2 ~ 3, then decolorized and filtered, reduced pressure and concentrated, then adjusted ph = 2 ~ 3, cooled and filtered
Crystallization is the finished product.
