121-70-0 - Introduction
Phenylphosphonic acid is an organic compound with the chemical formula C6H5PO3H2. The following is the introduction of the nature, use, preparation method and safety information of benzene phosphonic acid:
Nature:
-Phenylphosphonic acid is a colorless crystalline solid with strong hygroscopicity.
-soluble in water, a weak acid.
-Decomposes at high temperature to produce toxic phosphorus oxide compounds.
Use:
-Phenylphosphonic acid is mainly used as a reducing agent and oxidant in organic synthesis.
-In organic synthesis, it can be used to prepare phosphorus-containing compounds, such as phosphonates and phosphonic acid derivatives.
-It can also be used as an additive in the electroplating industry to improve the uniformity and quality of the coating.
-It can also be used as a ligand in some metal-catalyzed reactions.
Method:
The preparation of phenylphosphonic acid generally employs the reaction of phosphoric acid with phenol. Phenol is first reacted with an excess of phosphoric acid under acidic conditions to give phenylphosphonates, which are then hydrolyzed to give phenylphosphonic acid.
Safety Information:
-Phenylphosphonic acid is toxic and may pose a health hazard by contact or inhalation. Care should be taken to avoid skin contact and inhalation of its dust.
-During handling and storage, appropriate protective measures should be taken, such as wearing gloves, safety glasses and protective masks.
-When discarded, it should be handled in accordance with relevant laws and regulations to avoid pollution to the environment.
