Methyl isobutyl acetophenone (MIBK) is an important organic chemical raw material, which is widely used in the fields of medicine, pesticide, spice, plastic and printing ink. This article will detail the properties and uses of methyl isobutyl acetophenone.

1. the properties of methyl isobutyl acetophenone

methyl isobutyl acetophenone is a colorless transparent liquid with a pleasant aroma. Its molecular formula is C10H14O and its molecular weight is 150.22. Methyl isobutyl acetophenone has a boiling point of 202°C, a density of 0.946g/cm³, a refractive index of 1.5058, and a flash point of 77°C. It is insoluble in water, but can be miscible with alcohol, ether, benzene and other organic solvents.

methyl isobutyl acetophenone has strong chemical stability and thermal stability, and can be stable under acidic or alkaline conditions. At the same time, it also has good antioxidant properties and can be used under high temperature and aerobic conditions.

2. the use of methyl isobutyl acetophenone

1. pharmaceutical intermediates

methyl isobutyl acetophenone is an important pharmaceutical intermediates, can be used for the synthesis of a variety of drugs. For example, it can be used in the production of anti-allergic drugs, anti-inflammatory drugs, anti-tumor drugs, etc.

2. pesticide adjuvant

methylisobutylacetophenone can be used as an adjuvant in pesticides, which can improve the efficacy and stability of pesticides. For example, it can be mixed with pesticides such as herbicides and pesticides to improve the permeability and dispersibility of pesticides.

3. Fragrance Ingredients

methylisobutylacetophenone has a pleasant aroma and is therefore widely used as a fragrance ingredient. It can be used to produce food flavor, daily chemical flavor, etc.

4. plastic additives

methyl isobutyl acetophenone can be used as plastic additives, can improve the processing performance and mechanical properties of plastics. For example, it can be added to plastics such as polyvinyl chloride and polypropylene to improve the toughness and fluidity of the plastic.

5. printing ink additive

methyl isobutyl acetophenone can be used as a printing ink additive to improve the printing performance and drying performance of the ink. For example, it can be added to offset printing inks, intaglio printing inks, etc., to improve the printability and drying speed of the inks.

In conclusion, methyl isobutyl acetophenone is an important organic chemical raw material and has a wide range of uses.
