1. Solubility: miscible with water and most organic solvents.
2. Stability: It is relatively stable at room temperature, but it is easy to decompose under high temperature, strong oxidant or acidic conditions.
Purpose:
1. As a buffer: used as an acid-base buffer to adjust the acid-base of the solution.
2. As a surfactant: It can be used as a raw material for synthesizing surfactants such as detergents, emulsifiers and stabilizers.
