Cresyl diphenyl phosphate Usage And Synthesis

Chemical Properties

Colorless, transparent liquid; very slight odor.Insoluble in water; soluble in most organic solvents except glycerol. Combustible.

Uses

Plasticizer, extreme-pressure lubricant, hydraulic fluids, gasoline additive, food packaging.

Definition

Probably seldom a pure compound, but a mixture of o-, m-, and p-cresyl and phenyl phosphates.

General Description

A clear transparent liquid with a very slight odor. Insoluble in water. Primary hazard is to the environment. Immediate steps should be taken to limit spread to the environment. Easily penetrates the soil to contaminate groundwater and nearby waterways.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Organophosphates, such as CRESYL DIPHENYL PHOSPHATE, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.

Health Hazard

Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution.

Fire Hazard

Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot.

Purification Methods

Distil it in a vacuum, then percolate it through a column of alumina. Finally, pass it through a packed column maintained at 150o to remove traces of volatile impurities in a countercurrent stream of nitrogen under reduced pressure. [Dobry & Keller J Phys Chem 61 1448 1947, Beilstein 6 IV 2130.]
