methyl phenylacetate uses
Methyl phenylacetate is utilized for partition coefficient measurement experiments. It is mainly used in the flavor industry and in perfumes to impart honey scents. Further, it acts as a precursor to prepare synthetic perfumes. It acts as an acylating agent and involved in the enantioselective acylation of beta-lactam intermediate using penicillin G amidase.
methyl phenylacetate synthesis
Methyl phenylacetate is synthesized from phenylacetonitrile by hydrolysis and esterification. Put methanol into a dry glass-lined reaction pot, stir and cool to below 30°C, add sulfuric acid dropwise, heat up to 90°C after adding, and start adding phenylacetonitrile dropwise, control the temperature at about 95°C, and finish adding in 1.5h. After reacting at 95-100 °C for 6 h, it was cooled to below 40 °C and diluted with water equivalent to about 0.6 times the reaction solution. The acid water was separated by standing, and a saturated sodium carbonate solution was added for neutralization and washing, and the aqueous layer was discarded. It is dehydrated with anhydrous calcium chloride and fractionated under reduced pressure to obtain methyl phenylacetate with a yield of 80%.
methyl phenylacetate good scents/methyl phenylacetate smell
Methyl phenylacetate has a strong odor similar to honey. This compound also occurs in brandy, capsicum, coffee, honey, pepper, and some wine. It is used in the flavor industry and in perfumes to impart honey scents.
structure for methyl phenylacetate/methyl phenylacetate structure
Methyl phenylacetate is an organic compound that is the methyl ester of phenylacetic acid, with the structural formula C6H5CH2COOCH3. It is a colorless liquid that is only slightly soluble in water, but soluble in most organic solvents.
chemical name of methyl phenylacetate
