Neopentybenzene - Introduction
(2,2-Dimethylpropyl) benzene, also known as o-di-tert-butylbenzene (OTB), has the following properties:
1. Physical properties: (2,2-dimethylpropyl) benzene is a colorless liquid with aromatic odor.
2. chemical properties: it is a stable compound, not easy to be oxidized, hydrolyzed or other chemical reactions. It is stable at room temperature and not volatile.
3. Solubility: It can be dissolved in general organic solvents, such as alcohols, ethers and ketones.
The application of (2,2-dimethylpropyl) benzene mainly includes the following aspects:
1. Solvent: Due to the good solubility of (2,2-dimethylpropyl) benzene in most organic solvents, it is often used as a solvent, especially in the production of coatings, adhesives and resins.
2. Chemical intermediate: It can also be used as an important chemical intermediate for the synthesis of other organic compounds, such as polymers, dyes and drugs.
The method for preparing (2,2-dimethylpropyl) benzene mainly includes the following steps:
1. Propyl chloride reacts with benzene under acidic conditions to generate propyl benzene.
2. Under alkaline conditions, propyl benzene reacts with butyl lithium to generate (2,2-dimethylpropyl) benzene.
For safety information, (2,2-dimethylpropyl) benzene is not currently classified as a carcinogen or a teratogenic substance. However, as an organic compound, it still has a certain degree of danger. Contact with skin and eyes should be avoided and use in a well-ventilated place. During use, attention should be paid to fire prevention measures to avoid contact with strong oxidants and acidic substances. In addition, the handling and storage, should comply with the relevant safety procedures and measures.
