Dec 10,2021
P-methylacetophenone is a colorless needle-like crystal or a colorless to almost colorless liquid. This product has a fragrance similar to Crataegus flower, and has the fragrance of alfalfa, honey, and strawberry. The fragrance of flowers and fruits is sharp and sweet.
Uses
It can be used to prepare acacia and lilac flavors for soap, as well as fruit food flavors. From toluene and acetic anhydride in the presence of anhydrous aluminum trichloride, through the acetylation reaction system. P-methylacetophenone is an important fine chemical intermediate in the food and chemical industry. It can be used as a food additive and an intermediate for the production of other high value-added products. Its natural products are found in rosewood essential oil and mimosa flower oil.
Chemical synthesis
Hydration Reaction-In a typical procedure, a solution of phenyl acetylene (1.0 mmol) was mixed with water (3.0 mmol) and BAILs (1.0 mmol). The reaction mixture was stirred for 10 h at 333 K. The reaction mixture was then diluted with H2O and extracted with chloroform and dried over anhydrous Na2SO4. The reaction mixture was analyzed using gas chromatography (Yonglin 6100; BP-5; 30 m × 0.25 mm × 0.25 μm). The products were identified by GC-MS (Shimadzu QP-5000; 30 m long, 0.25 mm i.d., with a 0.25-μm-thick capillary column, DB-1) and authentic samples obtained from Aldrich.Aqueous portion of the reaction mixture was evaporated to remove the water. Residue was washed three-four times with diethyl ether to remove any organic impurity. Finally, ionic liquid portion was dried under vacuum at 353 K for 4 h. The recovered ionic liquid was used in the recycling experiments.
