2511-09-3 - Introduction
ethyl phenyl phosphate is an introduction to some properties, uses, formulation and safety information about ethyl phenophinate:
Nature:
-Appearance: Ethyl phenylphosphonate is a colorless to slightly yellow liquid.
-Solubility: It is soluble in many organic solvents such as ethers, alcohols, and ketones, but insoluble in water.
-Stability: It is relatively stable under conventional storage conditions, but can be affected by strong oxidants and acids.
Use:
-Ethyl phenylphosphonate is an important intermediate in organic synthesis, widely used in many chemical reactions.
-Ethyl phenylphosphonate is also used as a phosphorus source compound for the synthesis of catalysts and metal organic compounds.
Method:
The preparation method of ethyl phenyl phosphate is mainly obtained by the reaction of benzene phosphonic acid and alcohol.
1. First, mix phenylphosphonic acid with an appropriate alcohol (such as ethanol) under the protection of an inert gas.
2. Add an acidic catalyst, such as trifluoromethanesulfonic acid or trimethyl phosphate, to promote the reaction.
3. The reaction is carried out at an appropriate temperature and time, usually room temperature until the reactant is completely consumed.
4. After the reaction is over, the ethyl phenyl phosphate product is separated from the reaction mixture by distillation or solvent extraction.
Safety Information:
- ethyl phenyl phosphate is a flammable liquid and should be stored in a cool, ventilated place away from sources of fire.
-When using or operating ethyl phenosphinate, you should wear appropriate personal protective equipment, such as gloves and safety glasses.
-Avoid inhaling its vapors or direct contact with skin. In case of contact, rinse immediately with water.
-When handling ethyl phenophosphinate, you should follow the correct safety operating procedures and refer to the relevant safety data sheet.
