2-Phosphonobutane-1,2,4-tricarboxylic acid Chemical Properties,Usage,Production

Description

2-Phosphonobutane-1,2,4-tricarboxylic acid(PBTC) is the latest generation of internationally popular phosphine carboxylic acid, and it is one of the most widely used and best-performing products in the compounding of high-efficiency scale and corrosion inhibitors. It is especially suitable for water quality conditions of high temperature, high hardness, high alkalinity, high pH, and high concentration ratio, and has good scale inhibition performance for calcium carbonate scale and calcium phosphate scale.

Uses

PBTC is the most widely used in the compounding of high-efficiency scale and corrosion inhibitors, is one of the products with the best performance, and is also an excellent stabilizer for zinc salts. It is widely used in the corrosion and scale inhibition of circulating cooling water system and oilfield water injection system, especially suitable for compounding with zinc salt and copolymer. It can be used as a chelating agent and metal cleaning agent in the washing industry.

Chemical Properties

2-Phosphonobutane-1,2,4-tricarboxylic acid (PBTC)is colorless or light yellow transparent liquid. Relative density (20°C) 1.275. Freezing point -15°C. Has excellent scale and corrosion inhibition properties. Acid resistance, alkali resistance, oxidant resistance. When pH>14, it still does not hydrolyze, and the thermal stability is good.
