Калий фосфорнокислый пиро

Химические свойства

White crystalline powder

Использование

Potassium pyrophosphate is mainly used as an emulsifier, quality improver and metal ion chelating agent. It can be found in herbicidal compositions as a spray adjuvant. It is also used as an anionic dispersant in water-based (latex) paints.

Общее описание

Potassium tetrapyro phosphate is a whitish-colored powdered solid dissolved in an organic solvent. Potassium pyrophosphate may be toxic by ingestion. Contact with the substance should be avoided. The solvent may be flammable.

Реакции воздуха и воды

Soluble in water.

Профиль реактивности

Salts, basic, such as POTASSIUM TETRAPYRO PHOSPHATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.

Угроза здоровью

Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Пожароопасность

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.
