Nitrilotrimethylphosphonic acid is a colorless or slightly greenish crystalline free-flowing powder, readily soluble in water, acids ..
Insoluble in organic solvents. Nitrilotrimethylphosphonic acid is a combustible substance, according to the degree of impact on the body, it belongs to substances of the 3rd hazard class.
It is used in the oil industry as a regulator of the physicochemical properties of drilling and cement slurries, as an inhibitor of salt deposition in production processes oil, in construction as a retarder of 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 the deposition of sulfate and carbonate salts completely prevents scale deposition in well equipment and in heat exchangers of installations thermochemical dehydration and desalination of oil.
When drilling wells, NTF acid effectively reduces the viscosity of natural muds, remaining stable for a long time.
