Physical and chemical characteristics                                                             

Physical properties

Appearance: White, innoxious, flavorless crystalline powder.

Solubility: Soluble in methanol, formaldehyde, acetic acid, hot ethylene glycol, glycerol, pyridine; Slightly soluble in water, ethanol; Do not dissolve in ether, benzene and carbon tetrachloride. Weakly alkaline aqueous solution. 

Chemical properties

Melamine presents alkalescence, can react with various acidums to generate melamine salt. In strong acid or strong alkali liquor, melamine will hydrolyze---amido group will be slowly replaced by hydroxyl, thus generate ammeline, Cyanuric Acid and Ammelide. It can react with aldehydes to produce addition compounds. Among them, the reaction of melamine and formalin is the most important part.
