What is 2-Phenylpropionaldehyde?
Solanum aldehyde (2-phenylpropionaldehyde) is a sort of valuable perfume, which is not discovered in nature and also belongs to synthetic perfume. Its look is anemic liquid. Somewhat soluble in water and also soluble in organic solvents such as ethanol. Solanum aldehyde has strong hyacinth fresh flower fragrance, and is generally utilized in hyacinth, lavender, Lily and also other day-to-day significance. It can additionally be used in a small amount in edible essence. At the same time, it is additionally a crucial chemical resources, which is widely made use of in seasonings, drugs, dyes, pesticides and also various other sectors.
2-phenylpropionaldehyde belongs to the phenylacetaldehyde household. These are substances containing phenylacetaldehyde moieties consisting of phenyl replaced by acetaldehyde at the 2nd position. 2-phenylpropionaldehyde is a substance normally located in various foods, consisting of baked nuts, cooked potatoes, cheese, red wine, fruits, vegetables, coffee, tea and also chocolate. 2-phenylpropionaldehyde was made use of as flavor agent. When taken in, 2-phenylpropionaldehyde can be transformed to phenyl substituted carboxylic acid, which can be integrated with glucuronic acid and also excreted from pee. 2-phenylpropionaldehyde can additionally be β- Oxidation generates benzoic acid or phenylacetic acid by-products, which integrate with glycine or glutamine and are then secreted from the pee.
- Solanal has a strong hyacinth fresh and floral aroma, and is mainly used in daily fragrances such as hyacinth, lilac, and lily. It can also be used in trace amounts in food flavors. At the same time, it is also an important chemical raw material, which is widely used in spices, pharmaceuticals, dyes and pesticides and other industries.
- GB 2760–1996 stipulates that the edible spices are allowed to be used. Mainly used for the preparation of melons, almonds, cherries, peaches, plums and other flavors.
- 2-Phenylpropionaldehyde is a synthetic n, β- Precursor of trimethyl phenylethylamine hydrochloride (t796625).
- 2-Phenylpropionaldehyde (hydrotropaldhyde) was used as a substrate to study the noracylation activity of recombinant myoglobin, RMB (1).

Preparation of 2-Phenylpropionaldehyde
Using α-methylstyrene as the starting material, firstly, α-methyl styrene oxide is prepared, which is then decomposed and isomerized into solanine by heating.
From acetophenone and ethyl monochloroacetate as starting materials, solanine can also be obtained according to Darzens reaction.
Production Method of 2-Phenylpropionaldehyde
In a 2L three-necked flask equipped with a thermometer, stirring, dropping funnel and condensation column, add 800 g of toluene, 180 g of α-methyl styrene, and 650 g of sodium percarbonate, stir vigorously, heat up to 55 ° C, and slowly drop acetic anhydride 300g, continue the reflux reaction after the dropwise addition, follow the reaction by chromatography, until the α-methylstyrene is completely converted, the reaction time is about 25 to 30 hours, filter out the solid inorganic substances, wash with water to remove the residual peroxide, and recover the solvent. Rectification is carried out to obtain 2-phenylene oxide with a content of ≥98%, and the yield is 90-95%.
In a 500ml three-necked flask equipped with a thermometer, stirring, dropping funnel and condensation column, add 200g of toluene, stir and heat up to 130°C, slowly drop 120g of the 2-phenylene oxide prepared above, after the dropwise addition is completed Continue the reflux reaction, follow the reaction by chromatography, until the 2-phenylene oxide is completely converted, the reaction time is about 15 to 20 hours, and the solvent is recovered and then rectified to obtain solanine with a content of ≥98%, and the yield is 88 to 92%. %.
