Melamine (CAS No. 108-78-1) is used in the production of melamine resins, typically by reaction with formaldehyde. It has many indus trial uses, including in the production of laminates, glues, adhesives, moulding compounds, coatings and flame retardants.
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.
Physical properties:
White crystalline powder, innoxious, flavorless.
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.
Application
The application state of melamine :
1.Melamine is a semi-finished product in organic chemical industry with even structure and vast applications; it is mainly used as the material to produce melamine formaldehyde (MF) colophony. Owning the abilities of fire-resistant, water-resistant, hot-resistant, age-preventing, electric arc resistant, bearing chemical corruption, perfect insulation capability, gloss grade, and machinery intention, and good thermal-setting capacity, it is widely used in wood, plastic, dope, paper-making, textile industry, leather, electric, and medicine, etc.
2.1),DECORATIVE PANEL:It can be made of fireproofing,heat-resistant laminate,decorating material.
2),DOPE:It can be made of metal coating,and high-grade amino resin decorative paint.
3)It can be made of malamine plastic, white and shatterproof household utensils,sanitary ware,melamine tableware,and other insulation material.
4)Papers:It can be used as paper handling agent,to be made of anti-wrinkle,anti-shrinkage,non-perishable high grade papers.
3.It can also used to made fabric finishing agent,run leather tanning agent,polish and anti-agent,rubber adhesives,efficent water-reducing cement,steel delution agent.
4.Method of manufacture:
Melamine is manufactured by the reaction of urea under high pressure and high temperature.
5.Storage:
Store in a cool well-ventilated place, not with acids and oxidants were mixed storage transport.
AmmoniumChloride
Other Names: Salmiac; Amchlor; Ammonium muriate...MF: C7H11NO2 Storage
1) Store in a cool,dry and ventilated house away from moisture
2) Avoid handling or transporting together with acidic or alkaline substances
3) Prevent the material from rain and insolation
4) Load and unload carefully and protect from package damage
5) In the event of a fire,use water,soil or carbon dioxide fire extinguishing media
Properties&Applications:
Ammonium chloride is Colorless cubic crystal or white crystal; It is easily soluble in water, liquid ammonia, and slightly dissolves in alcohol, while not in acetone and ether.
Ammonium chloride is used for adhesive, detergent, mordant of printing and dyeing, galvanization, electric welding, tannage, pharmacy, photograph, and other industries as well.
