2-Methylimidazole is an organic compound that is structurally related to imidazole with the chemical formula CH3C3H2N2H. It is a white or colorless solid that is highly soluble in polar organic solvents and water.

It is intermediate of metronidazole and fodder growth promoter. It is mainly used as curing accelerator for powder forming and powder coating. It can be used as the curing agent of epoxy resin and dye auxiliaries of fibre textile, as well as additives for the preparation of foam plastics.

Barium sulphate is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is odorless and insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. The white opaque appearance and its high density are exploited in its main applications.

Uses :

Hardness control is a highly soluble, dry powder product used for the reduction of hardness in boilers. It will precipitate calcium hardness as a non-adherent sludge.

Hardness control transforms scaling salts like carbons, sulphates, and calcium or magnesium chlorides in phosphates that do not adhere to the exchange surfaces and are easily blowed down. It is used in conjunction with alkalinity control for the prevention of scale and corrosion in low and high-pressure boiler systems.
