PHOSPHOROUS ACID TRIS(2-ETHYLHEXYL) ESTER Usage And Synthesis

Chemical Properties

Straw-colored liquid. Insoluble in water. Combustible.

Uses

Synthesis, plasticizers, stabilizers, lubricant and grease additives, flameproofing compositions.

Reactivity Profile

PHOSPHOROUS ACID TRIS(2-ETHYLHEXYL) ESTER is a reducing agent. They slowly generate flammable or noxious gases in contact with water. Phosphides react quickly upon contact with moisture or acids to give the very toxic gas phosphine; phosphides also can react vigorously with oxidizing materials. In general, materials in this group are incompatible with oxidizers such as atmospheric oxygen. They are violently incompatible with acids, particularly oxidizing acids.

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition PHOSPHOROUS ACID TRIS(2-ETHYLHEXYL) ESTER emits toxic fumes.
