Structural Formula:

Properties:
Sodium PASP is a water soluble polymer. It is a green water treatment agent, with properties of non-phosphor, non-nitrogen,

non-pollution and fully biodegradation. PASP has good scale inhibition on calcium carbonate, calcium sulfate, barium sulfate,

calcium phosphate, etc. Its scale inhibition rate for calcium carbonate is 100%. Moreover, Sodium PASP has good dispersion

and corrosion inhibition properties to metal equipment.
Sodium PASP is an alternative of phosphor-containing Water Treatment Chemicals, avoiding water system eutrophication and

second pollution. 

Specification:

Usage:
Sodium PASP can be used as scale and corrosion inhibitor in industrial circulating cool water system, boiler water, reverse

osmosis, oilfield water and desalination plant. The effects will be even better than ordinary organophosphines when used in

situation of high hardness, high alkaline, high pH value and high concentration index. When built with PBTCA, the synergism

is obvious. Due to its green and non-pollution to environment, Sodium PASP can be used as accessory ingredients in daily

and fine chemicals.
Sodium PASP can be used in agricultural as nutrient absorption intensifier to improve the production of vegetable, melon and

fruit, and flowers.

When used together with pesticide, its effects will be improved.
