779-90-8 - Introduction
1,3,5-Triacetylbenzene is an organic compound with the chemical formula C15H12O3. The following is a description of its nature, use, preparation and safety information:
Nature:
1,3,5-Triacetylbenzene is a white crystalline solid with a distinctive aromatic odor. It has a melting point of about 88-91 degrees Celsius and a boiling point of 252-254 degrees Celsius. It is insoluble in water at normal temperature, but soluble in organic solvents such as ethers, alcohols and ketones.
Use:
1,3,5-Triacetylbenzene is mainly used as an intermediate in organic synthesis. It can be used to prepare compounds with fluorescent properties, and is commonly used in the preparation of fluorescent dyes, fluorescent coatings and fluorescent materials. In addition, it can also be used in the synthesis of other organic compounds, such as pharmaceutical intermediates and flavors and fragrances.
Preparation Method:
1,3,5-Triacetylbenzene is usually prepared by acylation of triphenyl ethyl ketone. In the reaction, triphenyl ethyl ketone and anhydride are esterified and acylated in the presence of a suitable catalyst to generate 1,3,5-Triacetylbenzene.
Safety Information:
1,3,5-Triacetylbenzene is generally stable and relatively harmless under normal operating conditions. However, contact with strong oxidizing agents and strong acids should be avoided in order to avoid potentially dangerous reactions. Wear protective goggles and gloves to ensure adequate ventilation when handling or using this compound. If skin contact or inhalation occurs, rinse immediately with plenty of water and seek medical help.
