- in chemical industry — for production of dyes, polyfoams and other organic products, fluoric reactants, goods of household chemicals, fillers in fire extinguishers, for department of carbon dioxide, hydrogen sulfide from gas mixes (gas is absorbed in hydrocarbonate solution at elevated pressure and the lowered temperature, solution is recovered at heating and the lowered pressure).
- in light industry — in production of bottom rubbers and artificial skin, tanning production (tanning and neutralization of skin), the textile industry (finishing of silk and cotton fabrics).
