1-(1,1-dimethyl-ethyl)-3-methyl-benzene - Introduction
3-tert-butyltoluene, also known as p-tert-butyltoluene, is an organic compound. The following is an introduction to its nature, use, preparation and safety information:
Nature:
1. Appearance: 3-tert-butyl toluene is a colorless to slightly yellow liquid.
2. Solubility: It is soluble in organic solvents such as ether and benzene at room temperature.
3. melting point and boiling point: its melting point is -55 ℃, boiling point is 208-209 ℃.
4. Stability: 3-tert-butyl toluene is stable, not easy to decompose or chemically react, and has good heat resistance.
Use:
1. Additives: It can be used as additives for fuels, lubricants and polymers, and has the effect of improving product performance in industry.
2. Solvent: Due to its good solubility, it can be used as a solvent, especially suitable for some organic reactions and chemical analysis.
3. Chemical intermediates: 3-tert-butyl toluene can also be used as an intermediate for the synthesis of other organic compounds, such as drugs, spices and dyes.
Preparation Method:
3-tert-butyltoluene is usually prepared by esterification of benzyl alcohol with tert-butyl alcohol under acidic conditions. Benzyl alcohol is first mixed with t-butanol and then an acidic catalyst, such as dilute sulfuric acid or a polyphenol phosphate ester, is added. At a suitable temperature and reaction time, the reaction proceeds to yield 3-tert-butyltoluene.
Safety Information:
1. 3-tert-butyltoluene has low toxicity and no obvious carcinogenic or teratogenic effects.
2. during use or storage, avoid contact with strong oxidants to prevent dangerous accidents.
3. The report has not yet mentioned its potential impact on the environment, so appropriate precautions should be taken when handling and disposing of waste.
4. in use, need to take appropriate protective measures, such as wearing gloves and goggles, and ensure good ventilation.
