166328-16-1 - Introduction
ACID is an organic compound with the chemical formula C7H7BClF. Its properties are as follows:
1. Appearance: ACID is a colorless crystalline solid.
2. Melting point: Its melting point is 90-93 ° C.
3. Solubility: It is slightly soluble in water and soluble in organic solvents such as ethanol and chloroform.
The main uses of ACID are as follows:
1. As a reagent in Organic Synthesis: It can be used as a catalyst or reagent in organic synthesis reactions.
2. Used to prepare liquid crystal and optical materials: It can be used to synthesize materials with liquid crystal properties or as a component of optical materials.
The method of preparing the anion ACID is as follows:
1. Fluorination of benzodioxolane: First, benzodioxolane reacts with hydrofluoric acid to obtain the fluoride of benzodioxolane. Then, 2-fluoro-5-hydroxybenzodioxolane is obtained by reacting sodium sulfite with fluoride. Finally, boron trimethyl ether and cobalt trichlorobiphenyl complex were used to react to give oxometalate.
2. By electrophilic substitution: First, P-toluene is reacted with hydrogen fluoride to obtain a fluorinated substance of p-toluene. Then, the fluoro and trichloroborane are reacted to obtain the ACID.
Regarding its safety information, the following points should be noted:
1. Toxicity: ACID may be harmful to health, should avoid inhalation or contact with skin and eyes.
2. Combustibility: It is combustible at high temperatures and should be kept away from open flames and heat sources.
3. Storage: should be stored in a sealed, dry, cool place, away from oxidants and combustibles.
4. Disposal: Disposal in a compliant waste treatment facility, complying with local regulations.
