Methyl tert-butyl acetophenone (MTBE) is a colorless and transparent organic compound with a special pungent odor. It has a wide range of uses in the field of chemical production raw materials, often used as solvents, additives and reaction intermediates. This article will detail the properties and uses of methyl tert-butyl acetophenone.

1. the properties of methyl tert-butyl acetophenone

1. Physical properties
methyl tert-butyl acetophenone is a colorless and transparent liquid with a special smell. It has a boiling point of 116.5°C, a density of 0.866g/cm³, a flash point of 21°C, and is insoluble in water, but soluble in most organic solvents.

2. chemical properties of
methyl tert butyl acetophenone has certain chemical stability, but it is easy to hydrolyze under acidic conditions. In addition, it can also react with alcohol, acid, alkali and other compounds to generate the corresponding derivatives.

2. methyl tert-butyl acetophenone use

1. solvent
methyl tert-butyl acetophenone is an excellent solvent, can be used in the production of coatings, inks, adhesives and other products. Because of its good solubility and volatility, it can improve the leveling and drying speed of the coating, so it is widely used in the production of coatings in the automotive, construction, furniture and other industries.

2. additive
methyl tert-butyl acetophenone can be used as gasoline additive, which can improve the octane number of gasoline and reduce the emission of harmful substances in automobile exhaust. At the same time, it can also be used as an additive for polymer materials such as plastics and rubber, which can improve the processing and mechanical properties of materials.

3. reaction intermediate
methyl tert-butyl acetophenone can be used as a reaction intermediate for the production of drugs, pesticides, spices and other fine chemicals. For example, it can undergo a condensation reaction with an aldehyde compound to form the corresponding ketone compound, which is further derivatized into a drug or fragrance.

3. methyl tert-butyl acetophenone production method

methyl tert-butyl acetophenone production method mainly has the following several kinds:

1. esterification method: by acetophenone and isobutylene in the presence of acidic catalyst esterification.
2. Alkylation method: it is obtained by alkylation reaction of acetophenone and isobutylene in the presence of acidic catalyst.
Precautions for
4. of methyl tert-butyl acetophenone

When operating and using methyl tert-butyl acetophenone, you need to pay attention to the following:

1. Methyl tert-butyl acetophenone has a certain pungent Odor, Long-term contact and inhalation should be avoided.
2. In the process of storage and use, should maintain good ventilation, avoid open flame and high temperature environment.
3. Methyl tert-butyl acetophenone should be stored in a cool and dry place, avoid direct sunlight and high temperature environment.
