PROPERTIES
2-Phosphonobutane-1,2,4,-tricarboxylic Acid (PBTCA) is a very effective scale inhibitor used in various industrial applications. Due to its higher performance properties it is a very cost effective inhibitor compared to standard Phosphonates such as HEDP/ATMP. This is mainly due to superior stability to chlorine, bleach and bromine. In cooling water PBTC performs well at high PH or temperatures. It further shows high effectiveness in high alkaline solutions such as industrial cleaners.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. PBTCA is a 50% aqueous solution of 2-phosphonobutane-1, 2, 4-tricarboxylic acid (PBTCA) designed to control calcium scale formation and precipitation in highly stressed alkaline Industrial Water Treatment (IWT) and boiler systems. PBTC has been widely used in industry as a sequestering agent and calcium carbonate scale inhibitor for applications in industrial water treatment and industrial cleaning. 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.
USAGE
PBTCA is a high efficient agent as scale and corrosion inhibitor. PBTCA 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. PBTCA 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 otherWater Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred. It is mainly used as Scale & Corrosion Inhibitor in Cooling, Boiler & Field Water Treatment. PTBCA is a high efficient agent as scale and corrosion inhibitor.

Exposure Controls/Personal Protection
Engineering Controls: None established
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator (NIOSH type N95 or better filters) may be worn. If oil particles (e.g. lubricants, cutting fluids, glycerin, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
