Benzene, neopentyl- - Introduction

(2,2-dimethylpropyl) benzene, also known as o-tert butylbenzene (OTB),

Nature:
1. Physical properties: (2,2-dimethylpropyl) benzene is a colorless liquid with an aromatic odor.
2. Chemical properties: It is a stable compound that is not easily oxidized, hydrolyzed, or undergoes other chemical reactions. It is stable at room temperature and not easily volatile.
3. Solubility: It can dissolve in general organic solvents such as alcohols, ethers, and ketones.

Usage:
Solvent: (2,2-dimethylpropyl) benzene has good solubility in most organic solvents and is often used as a solvent, especially suitable for the production of coatings, adhesives, and resins.

Method:
The method for preparing (2,2-dimethylpropyl) benzene mainly includes the following steps:
React propyl chloride with benzene under acidic conditions to produce propyl benzene.
Under alkaline conditions, propylbenzene reacts with butyl lithium to produce (2,2-dimethylpropyl) benzene.

Security information:
1. (2,2-dimethylpropyl) benzene is currently not classified as a carcinogen or teratogen. As an organic compound, it still carries certain risks.
2. Avoid contact with skin and eyes, and ensure use in well ventilated areas.
3. During use, attention should be paid to fire prevention measures to avoid contact with strong oxidants and acidic substances.
4. When handling and storing, relevant safety operating procedures and measures should be followed.
