Acid melange
GOST (State standard) 1500?78
Nitric acid (HNO3) and sulphuric nitrate (H2SO4) blend
Use:
The product is used for production of nitro-sulphuric acids, semi-finished products and synthetic colorants.
Characteristics:
Not flammable, fire hazardous liquid, strong oxidant. Dissolves in water without limit. In certain conditions nitrates organic materials and increases their flammability. Causes spontaneous combustion of many materials on contact.
Transportation:
The material is transported by rail in railway tank-cars for melange transportation.
Guaranteed shelf life:
According to the nitrogen oxides content from 15 April till 15 October – 1 month, during the rest of the time – 2 years.
