Properties and stability
None
Storage method
Stored in a cool, dry place and sealed.
Synthesis method
1. Drop ethylenediamine into hydrochloric acid under cooling, and finish the addition in about 4 hours. The end point is ph=3,
After the reaction is completed, stop cooling, decolorize, and filter. The filtrate is evaporated under normal pressure, cooled to precipitate crystals, filtered to dryness, and washed once with distilled water to obtain the finished product.
Purpose
1. Used as analytical reagent. Used in organic synthesis, pharmaceutical industry, etc.
