1-[2-(trifluoromethoxy)phenyl]ethan-1-one - Introduction

2-(trifluoromethoxy)acetophenone is an organic compound with the chemical formula C9H7O2CF3. The following is a description of its nature, use, preparation and safety information:

Nature:
2-(trifluoromethoxy)acetophenone is a colorless and transparent liquid with a special aroma. It has a melting point of -29°C, a boiling point of 133-134°C and a density of 1.331g/cm³. It is soluble in organic solvents such as ethanol, acetone and dimethylformamide at normal temperature.

Use:
2-(trifluoromethoxy)acetophenone is commonly used as an intermediate in organic synthesis. It can be used as a raw material for the synthesis of drugs or pesticides, and can also be used in the preparation of organic optoelectronic devices. In addition, it can also be used as a component of spices and fragrances.

Method:
There are two main methods for preparing 2-(trifluoromethoxy)acetophenone. One method is to obtain 2-(trifluoromethoxy) acetyl chloride by reaction of trifluoromethyl alcohol and Chloroacetyl Chloride, and then react with aniline to generate 2-(trifluoromethoxy) phenylacetamide, finally, the target product was obtained by acid-catalyzed hydrolysis reaction. Another method is to diazotization of benzoic acid as raw material to produce diazotized benzoic acid methyl ester, which is then reacted with trifluoromethyl ether to obtain 2-(trifluoromethoxy)acetophenone.

Safety Information:
2-(trifluoromethoxy)acetophenone is a flammable liquid at room temperature and forms a flammable mixture when contacted with air. Its vapors can cause eye and respiratory irritation and may cause headaches, dizziness and coughing. Therefore, care should be taken to avoid contact with skin and eyes during handling and storage, and protective gloves and goggles should be worn when necessary. In addition, it should be used in a well-ventilated place, away from fire and heat sources. If inhaled or ingested, seek medical attention.
