CAS No. 40372-66-5
Molekulêre formule: C7H7O9P•Na4 Molekulêre gewicht: 358
Strukturele formule:
Eigenskippen:
PBTC•Na4 hat lege ynhâld fan phosphoric, syn struktuer befettet sawol phosphonic acid en carboxylic acid groep, dy't ynskeakelje syn goede skaal en corrosie remming eigenskippen. De skaalremmingseigenskip ûnder hege temperatueren is folle better dan dy fan organofosfines. PBTC•Na4 kin ferbetterje de oplosberens fan sink sâlt, hat goede chlor oksidaasje tolerânsje en goede gearstalde synergy. De fêste steat is maklik deliquescence.

Gebrûk:
PBTC•Na4 is a widely used and high effective agent as composite scale and corrosion inhibitor, it is also an excellent stabilizer for zinc salt. PBTC•Na4 is used as scale and corrosion inhibitor in circulating cool water system and oilfield refill water system, especially used together with zinc salt and copolymer. PBTC•Na4 can be used in situations of high temperature, high hardness, high alkaline and high concentration index, PBTC•Na4 wurdt brûkt as chelating agent en metaal detergent yn lavation fjilden.
PBTC•Na4 wurdt meastal brûkt tegearre mei sink sâlt, copolymer, organofosfine, imidazole en oare Water Treatment Chemicals.
