21778-19-8 - Introduction
Methoxyphenylphosphonic acid(Methoxyphenylphosphonic acid) is an organic compound with the chemical formula C7H9O3P. It is a colorless crystalline solid, soluble in water and some organic solvents.
Methoxyphenylphosphonicacid has the following properties:
-It is a weak acid that reacts with a strong base to form the corresponding salt.
-it has the chemical properties of phosphonic acid, can be esterification, addition reaction and other reactions.
-It is relatively stable in the air, but may decompose under the action of high temperature or ultraviolet light.
The main uses of Methoxyphenylphosphonicacid include:
-As an intermediate for the synthesis of organic phosphate esters, it can be used to prepare pesticides, light stabilizers, polymer plasticizers, etc.
-As a corrosion inhibitor, it can be used in metal surface treatment, cooling water treatment and other fields.
-Can be used as a ligand in some catalytic reactions.
The method for preparing methoxyphenylphosphonic acid is usually obtained by the reaction of methanol and p-tolylphosphonic acid. As a specific step, P-tolylphosphonic acid is dissolved in methanol, and then an acid catalyst is added to allow the reaction to proceed. Finally, the pure product is obtained by filtration or distillation.
Note the following security information when using or storing Methoxyphenylphosphonicacid:
-It is an organic compound that may cause irritation and harm to the human body. Direct contact with skin, eyes or inhalation of its vapor should be avoided.
-Wear personal protective equipment including goggles, gloves and appropriate protective clothing during operation.
-During storage and use, keep away from fire sources, high temperature and oxidants to avoid fire or explosion.
-Waste disposal should be carried out in accordance with local regulations to avoid environmental pollution.
