26444-49-5 Usage
Description
Cresyl diphenyl phosphate is a colorless, transparent liquid with a very slight odor. It is insoluble in water but soluble in most organic solvents except glycerol. It is a mixture of o-, m-, and p-cresyl and phenyl phosphates and is combustible. Its primary hazard is to the environment, and immediate steps should be taken to limit its spread to the environment as it can easily penetrate the soil and contaminate groundwater and nearby waterways.
Uses
Used in Plasticizer Industry:
Cresyl diphenyl phosphate is used as a plasticizer to increase the flexibility and workability of plastics. It is added to polymers to reduce their brittleness and improve their processability.
Used in Extreme-Pressure Lubricant Industry:
Cresyl diphenyl phosphate is used as an extreme-pressure lubricant to reduce friction and wear between moving parts in high-pressure applications. It provides a protective film that prevents metal-to-metal contact and reduces heat generation.
Used in Hydraulic Fluids Industry:
Cresyl diphenyl phosphate is used in hydraulic fluids to provide lubrication and reduce wear in hydraulic systems. It helps maintain the efficiency and longevity of hydraulic equipment by reducing friction and preventing corrosion.
Used in Gasoline Additive Industry:
Cresyl diphenyl phosphate is used as a gasoline additive to improve the performance and efficiency of internal combustion engines. It helps reduce engine knocking and improve fuel economy.
Used in Food Packaging Industry:
Cresyl diphenyl phosphate is used in food packaging materials to provide flexibility and durability. It helps protect food products from external factors such as moisture, oxygen, and microbial contamination, ensuring their freshness and safety.
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.]
Check Digit Verification of cas no
The CAS Registry Mumber 26444-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,4,4 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 26444-49:
(7*2)+(6*6)+(5*4)+(4*4)+(3*4)+(2*4)+(1*9)=115
115 % 10 = 5
So 26444-49-5 is a valid CAS Registry Number.
