Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer (AA/AMPS)
Acrylic Acid-2-Acrylamido-2-Methylpropane Sulfonic Acid Copolymer (AA/AMPS)
CAS No 40623-75-4
Structural Formula:
Properties:
AA/AMPS is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid (AMPS). Due to including carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong polarity) in this copolymer, AA/AMPS has high calcium tolerance and good scale inhibition for calcium phosphate, calcium carbonate and zinc scale. When built with organophosphines, the synergic effect is obvious. AA/AMPS is suitable to be used in water quality of high pH and high alkaline, it is one of the ideal scale inhibitor and dispersant on high concentration index.
Specification:
items index
appearance Colorless or light yellow viscous liquid
Solid content % 40min
Free monomer （as AA）% 0.8max
Density （20℃）g/cm3 1.15min
pH（1% solution） 3.5-4.5
Viscosity mpa.s 90-200
Usage:
AA/AMPS can be used as scale inhibitor and dispersant in open circulating cool water system, oilfield refill water system, metallurgy system and iron & steel plants to prevent sediment of ferric oxide. When built with organophosphorines and zinc salt, the suitable pH value is 7.0~9.5.
AA/AMPS can also be used as dyeing auxiliaries for textile.

2-Phosphonobutane -1,2,4-Tricarboxylic Acid(PBTCA)
2-Phosphonobutane -1,2,4-Tricarboxylic Acid(PBTCA)
CAS No. 37971-36-1 Dequest 7000
Molecular Formula: C7H11O9P Molecular weight: 270.13
Structural Formula:
Properties:
PBTCA has low content of phosphoric, has structural features of both phosphoric acid and carboxylic acid group, which enable its excellent scale and corrosion inhibition properties. Its antiscale property under high temperature is far better than that of organophosphines. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.
Specification:
items index
Appearance Colorless or light yellow transparent liquid
Active acid ％ 50.0min
Phosphorous acid（as PO33-）% 0.8max
Phosphoric acid (as PO43-)% 0.5max
Density （20℃）g/cm3 1.27min
pH（1％ water solution） 1.5~2.0
Usage:
PTBCA is a high efficient agent as scale and corrosion inhibitor. It is the excellent stabilizer for zinc salt. It is widely used in circulating cool water system and oilfield refill water system as scale and corrosion inhibitor, suitable to composite with zinc salt and copolymer. It can be used in situations of high temperature, high hardness, high alkali and high concentration index. In lavation fields, it is used as chelating agent and metal detergent.
PBTCA is usually used together with zinc salt, copolymer, organophosphine, imidazole and other water treatment agents. When used alone, the dosage of 5-15mg/L is preferred.
Package and Storage:
Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for one year in room shady and dry place.
Safety Protection:
Acidity, Avoid contact with eye and skin, once contacted, flush with water.

Diethylene Triamine Penta (Methylene Phosphonic Acid) (DTPMPA)
Diethylene Triamine Penta (Methylene Phosphonic Acid) (DTPMPA)
CAS No 15827-60-8 Dequest 2060
Molecular Formula: C9H28O15N3P5 Molecular weight: 573.2
Structural Formula:
Properties:
DTPMPA is innocuous, easy to be dissolved in acid solution. DTPMPA has excellent scale and corrosion inhibition and good thermal tolerance ability. DTPMPA can inhibit the scale formation of carbonate, sulfate and phosphate. On situation of alkali environment and high temperature (above 210℃) DTPMPA has better scale and corrosion inhibition effect than other organophosphines.

Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium (EDTMPS)
Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium (EDTMPS)
CAS No. 1429-50-1 Dequest: 2040
Molecular Formula: C6H12O12N2P4Na8 Molecular weight: 612.13
Structural Formula:
Properties:
EDTMPS is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion inhibitor.Its corrosion inhibition is 3~5 times better than that of inorganic polyphosphate. It can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. It shows excellent scale inhibition ability under temperature 200℃. It can dissociate into 8 positive-negative ions, thus can chelate with many metal ions to form polymer reticulation complex, to destroy the normal crystallization of calcium scale. EDTMPS shows better antiscale effects to calcium sulfate and barium sulfate.
