Introduction
2-Chloro-4-fluorotoluene. Its properties include:
1. Appearance: 2-chloro-4-fluorotoluene is a colorless liquid or white crystal.
2. Solubility: soluble in non-polar solvents, such as ethanol, acetone and ether, insoluble in water.
Its main uses are:
1. Chemical intermediates: 2-chloro-4-fluorotoluene plays an important role in organic synthesis as an important intermediate.
2. Pesticide: It is also used as one of the raw materials for pesticides. For example, it can be used to make pesticides and herbicides.
There are several ways to prepare 2-chloro-4-fluorotoluene, one of which is commonly used by fluorination and chlorination. In general, 2-chloro-4-fluorotoluene can be finally obtained by fluorinating with a fluorinating agent (such as hydrogen fluoride) on 2-chlorotoluene and then by chlorination with a chlorinating agent (such as aluminum chloride).
Safety information: 2-chloro-4-fluorotoluene is generally relatively safe under normal use conditions
1. Toxicity: 2-chloro-4-fluorotoluene can cause certain health hazards. Long-term exposure or inhalation may cause damage to the central nervous system, liver, and kidneys.
2. Explosiveness: 2-chloro-4-fluorotoluene is a flammable liquid, and its vapor can form a combustible mixture. It should be kept away from open flames and heat sources, and stored in a cool, well-ventilated place.
3. Personal protection: When handling 2-chloro-4-fluorotoluene, appropriate personal protective equipment such as gloves, protective eyewear, and protective clothing should be worn.
