Acid of нитрилотриметилфосфоновая 2931909090
is a colorless or slightly greenish crystalline free-flowing powder, readily soluble in water, acids ..
Insoluble in organic solvents. Nitrilotrimethylphosphonic acid is a flammable substance, according to the degree of impact on the body it belongs to the substances of the 3rd hazard class.
It is used in the oil industry as a regulator of the physicochemical properties of drilling and grouting fluids, as a scale inhibitor in oil production processes, in construction as a retarder for the setting time of concrete mixtures in the production of monolithic and prefabricated reinforced concrete, in heat power engineering as a scale inhibitor in various heat exchangers; in the pulp and paper industry in the process of bleaching all types of cellulose at the stage of chelation.
The use of NTF acid and its salts as an active principle in inhibitors of sulfate and carbonate salt deposition allows to completely prevent scale formation in well equipment and in heat exchangers of thermochemical oil dehydration and desalination units.
When drilling wells, NTF acid effectively reduces the viscosity of natural muds, remaining stable for a long time.
