1,2-bis(4-hydroxyphenyl)ethane-1,2-dione - Introduction
1,2-bis(4-hydroxyphenyl)ethane-1,2-dione, also known as 1,2-bis(4-hydroxyphenyl) ethanone, is an organic compound. Its chemical formula is C14H10O4 and its molecular weight is 242.23g/mol. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: 1,2-bis(4-hydroxyphenyl)ethane-1,2-dione is a pale yellow to tan crystalline solid.
-Melting point: approximately 222-225 degrees Celsius.
-Solubility: It is almost insoluble in water, but soluble in organic solvents such as ethanol and dichloromethane.
Use:
- 1,2-bis(4-hydroxyphenyl)ethane-1,2-dione can be used as an intermediate for the synthesis of organic dyes. Its existence makes the process of synthesizing organic dyes easier to control, thereby improving the stability and color vividness of the product.
-It is also used in the fields of coordination chemistry and organic synthesis, such as metal complex ligands or organic synthesis catalysts.
Method:
-A common synthesis method is to heat the reaction of p-hydroxybenzaldehyde and p-hydroxyacetophenone under alkaline conditions. The white precipitate produced by this reaction was purified by crystallization to give 1,2-bis(4-hydroxyphenyl)ethane-1,2-Dione.
Safety Information:
- 1,2-bis(4-hydroxyphenyl)ethane-1,2-Dione should avoid contact with oxidants and strong acids during use and storage to avoid unnecessary reactions and dangers.
-During operation, attention should be paid to avoid prolonged contact with skin and eyes to avoid irritation or damage.
-When handling or storing, it is necessary to take good ventilation measures and follow correct laboratory safety procedures.
-In case of accidental inhalation or ingestion, seek immediate medical help.
