Ethanedioic acid, 1,2-diphenyl ester - Introduction
Oxalicaciddiphenyllester is an organic compound with the chemical formula (C6H5COO)2C2O4. The following is a description of the nature, use, formulation and safety information of the oxalicaciddiphenyllester:
Nature:
-Appearance: the oxalicacid diphenylester is a white crystalline solid.
-Melting point: about 130-132 degrees Celsius.
-Solubility: Oxalicaciddiphenylester is soluble in many organic solvents, such as ethers, alcohols and ketones, but has low solubility in water.
Use:
- Oxalicaciddiphenylester can be used as a strong acid catalyst for esterification and ketone synthesis in organic synthesis.
-It can also be used as a precursor for polyimide and polyamide for the synthesis of high temperature resistant and high performance materials.
Preparation Method:
-A common method for preparing Oxalicaciddiphenylester is the reaction of benzyl alcohol and oxalic acid under acid catalysis. First, oxalic acid and formic acid are esterified to produce benzyl formate. Benzyl formate is then transesterified with benzyl alcohol to produce Oxalicaciddiphenylester.
Safety Information:
-oxalaciddiphenylester is stable and not easy to burn under general conditions, but may decompose at high temperatures to produce toxic gases.
-Because Oxalicaciddiphenylester is an organic acid, it may cause irritation and corrosion when contacted with skin and eyes.
-Wear appropriate protective gloves and goggles when using Oxalicaciddiphenylester, and make sure to operate in a well-ventilated place. In case of contact or inhalation, rinse immediately with water and seek medical help.
