Sulfuric acid
Sulfuric acid - colourless oily liquid, sometimes it is painted in dark color owing to a carbonization of organic substances.
The chemical composition of sulfuric acid is expressed by a formula H2SO4. Sulfuric acid mixes up with water in any ratios. The main physical and chemical properties of solutions of sulfuric acid depend on a ratio in her of water and teroxide of sulfur. Density of sulfuric acid with a mass fraction of monohydrate of 100% at a temperature of 20 0 °C - 1,8305 g/cm3.
Sulfuric acid - colourless oily liquid, sometimes it is painted in dark color owing to a carbonization of organic substances.
Sulfuric acid - is explosion-proof, at her contact with water there is a rough reaction to big allocation of heat, vapors and gases. Sulfuric acid - is toxic.
Notes:
In coordination with the consumer it is allowed to deliver the improved and technical sulfuric acid with a mass fraction of monohydrate to 98%.
Transport by rail in tanks and the motor transport in containers and barrels according to the rules of transportation of goods existing on each type of transport.
Sulfuric acid of the 1st and 2nd grade has to be stored in capacities from steel or special steel, both a not lined and acidproof brick-lined or acid resisting material.
The improved sulfuric acid has to be stored at the consumer in pure hermetically sealed capacities from stainless steel or capacities from steel,lined acid-resistant tile or a brick-lined.
Sulfuric acid is widely used in various branches of a national economy: in production of various mineral salts, organic products, aniline dyes, explosives, in oil, metallurgical, metalworking and other productions. A warranty period of storage of sulfuric acid – one month from the date of production.
