Details

2-Phenylpropionaldehyde, with the chemical formula C9H10O, is an organic compound that belongs to the aromatic aldehyde class. It is a colorless to light yellow liquid with a pungent odor and is widely used in spices, pharmaceuticals, pesticides and other fields. The following will introduce in detail the physical properties, chemical properties, preparation methods, applications, safety and environmental protection of 2-phenypropionaldehyde.

1. Physical properties The molecular weight of 2-phenylpropionaldehyde is 134.17500, the density is 1.002 g/mL at 25 °C, the boiling point is 92-94 °C (12 mm Hg), and the melting point is -60 °C. It is insoluble in water but soluble in organic solvents such as alcohols and ethers. At room temperature and pressure, 2-phenylpropionaldehyde is in a liquid state.

2. Chemical properties 2-phenylpropionaldehyde has high chemical activity and can undergo a variety of chemical reactions. For example, it can undergo a condensation reaction with alcohols to produce the corresponding acetal; Esterification reaction with carboxylic acids to form ester compounds; Under the action of a catalyst, a hydrogenation reaction can occur to generate the corresponding alcohols.

3. Preparation method The preparation methods of 2-phenylpropionaldehyde are mainly as follows:

1. It is formed by the condensation of acetyl benzene and ethyl chloroacetate under alkaline conditions. The specific process is as follows: in the reaction bottle equipped with stirrer and thermometer, acetyl benzene and ethyl chloroacetate are added, and then benzene dried with sodium metal is added, cooled in an ice water bath, sodium amino is added under stirring, the organic layer is separated, and 2-phenyl propionaldehyde is prepared by washing, drying, distillation and other steps.

2. It is obtained by distillation of methyl phenylethylene glycol at atmospheric pressure. The specific process is as follows: in the reaction bottle equipped with stirrer and thermometer, methylphenyl glycol is added, heated and distilled, and the corresponding fraction is collected to prepare 2-phenyl propionaldehyde.

3. It is prepared by the cleavage reaction of ethyl 3-phenyl-2,3-epoxybutyrate. The specific process is as follows: in the reaction bottle equipped with stirrer and thermometer, ethyl 3-phenyl-2,3-epoxybutyrate is added, and under the catalysis of sodium metal, a cracking reaction occurs to generate 2-phenyl propionaldehyde.

4. Application 2-phenylpropionaldehyde has a wide range of applications in the fields of spices, pharmaceuticals, pesticides, etc. As a spice, it has the characteristics of fragrance and floral, and can be used to mix flavors, perfumes, etc.; In the pharmaceutical field, 2-phenylpropionaldehyde is an important intermediate in the synthesis of certain drugs; In the field of pesticides, it can be used to prepare insecticides, fungicides, etc.

5. Safety and environmental protection 2-Phenylpropionaldehyde has certain toxicity and irritation, irritation to the skin and eyes, and may cause discomfort when exposed to it for a long time. During operation, protective measures should be taken, such as wearing protective gloves and goggles. At the same time, because 2-phenylpropionaldehyde is easily soluble in organic solvents, it may cause pollution to the environment. Therefore, in the process of production and application, environmental protection measures should be strengthened to reduce the impact on the environment.

In conclusion, 2-phenylpropionaldehyde is an important organic compound with a wide range of uses. With the development of science and technology, the research on 2-phenylpropionaldehyde will continue to deepen, and its application in various fields will be more extensive.
