Introduction

Cresol, chemically known as methylphenol (English name Cresol), is an organic compound. The following is an introduction to the properties, uses, preparation methods and safety information of p-toluenol:

 

Quality:

Appearance: Cresol is a colorless or yellowish liquid with a special phenolic aroma.

Solubility: It is soluble in alcohols, ethers and ethers, and slightly soluble in water.

Chemical properties: Cresol is an acidic substance that reacts with alkali to form the corresponding salt.

 

Use:

Industrial uses: Cresol is used as a preservative, disinfectant, and solvent in the manufacture of preservatives. It also acts as a catalyst and solvent in the rubber and resin industries.

Agricultural uses: Toluene can be used in the agricultural sector as an insecticide and fungicide.

 

Method:

There are many ways to prepare toluenol, one of which is commonly used to obtain it through the oxidation reaction of toluene. The specific step is to first react toluene with oxygen to produce toluol under the action of a catalyst.

 

Safety Information:

Cresol is toxic, and direct contact or inhalation of large amounts of cresol can be harmful to health. Relevant safety operating procedures should be followed when in use, and appropriate protective equipment should be used.

Avoid prolonged contact with the skin and avoid inhaling its vapors.

When storing and handling toluenol, it needs to be properly sealed and stored away from ignition and high temperatures.
