BUSINESS OVERVIEW.
1 hydroxy ethylidene 1 1 diphosphonic acid hedp
cas no.: 2809 21 4
molecular formula: c2h8o7p2 molecular weight: 206.02
structural formula:
properties:
hedp is an organophosphoric acid corrosion inhibitor. it can chelate with fe cu and zn ions to form stable chelating compounds.it can dissolve the oxidized materials on these metals’ surfaces. hedp shows excellent scale and corrosion inhibition effects under temperature 250 #8451 . hedp has good chemical stability under high ph value hard to be hydrolyzed and hard to be decomposed under ordinary light and heat conditions. its acid alkali and chlorine oxidation tolerance are better than that of other organophosphoric acids salt . hedp can react with metal ions in water system to form hexa element chelating complex with calcium ion in particular. therefore hedp has good antiscale and visible threshold effects. when built together with other water treatment chemicals it shows good synergistic effects.
the solid state of hedp is crystal powder suitable for usage in winter and freezing districts. because of its high purity it can be used as cleaning agent in electronic fields and as additives in daily chemicals.

Amino trimethylene phosphonic acid atmp
cas no.: 6419 19 8
molecular formula: n ch2po3h2 3 molecular weight: 299.05
structural formula:
properties:
atmp has excellent chelation low threshold inhibition and lattice distortion ability. it can prevent scale formation calcium carbonate in particular in water system. atmp has good chemical stability and is hard to be hydrolyzed in water system. at high concentration it has good corrosion inhibition.
atmp is used in industrial circulating cool water system and oilfield water pipeline in fields of thermal power plant and oil refinery plant. atmp can decrease scale formation and inhibit corrosion of metal equipment and pipeline. atmp can be used as chelating agent in woven and dyeing industries and as metal surface treatment agent.
the solid state of atmp is crystal powder soluble in water easily deliquescence suitable for usage in winter and freezing districts. because of its high purity it can be used in woven dyeing industries and as metal surface treatment agent.
