2-フェニルアセトアミド

化学的特性2-Phenylacetamide, also known as alpha-toluamide or benzeneacetamide, belongs to the class of organic compounds known as phenylacetamides. These are amide derivatives of phenylacetic acids. Pure crystals are plate shaped and colorless to white. soluble in hot water, ethanol, slightly soluble in cold water, ether and benzene.

使用In agriculture, 2-Phenylacetamid can be used in the production of many important intermediates of pesticides, such as carbamine. In the field of dyes: it can react with some monomers with color to produce some important raw materials for blue and purple dyes. In the field of fragrances, it can be used as an important raw material for the synthesis of certain spices and flavors. 2-Phenylacetamide can also be used in the synthesis of organometallic, organic peroxide, organic peroxide ester, and other compounds, and can be used as a crosslinking agent for polymers, a film forming agent for coatings, a plasticizer for plastics, etc.

使用2-Phenylacetamide is used as a pharmaceutical intermediate in the production of penicillin G and phenobarbital, etc. It is also used in organic synthesis.

製造方法Synthesis of 2-phenylacetamide: Add concentrated hydrochloric acid to phenylacetonitrile, stir to dissolve, and react at 50°C for half an hour. Then slowly add water under cooling to separate out crystals, filter after cooling, wash with ice water to obtain crude product. The crude product was washed with sodium carbonate solution, then washed with ice water, and dried to obtain purer phenylacetamide.

純化方法Crystallise the acetamide repeatedly from absolute EtOH, EtOAc (m 160-161o) or H2O (m 159-160o). Dry it in vacuo over P2O5. [Beilstein 9 H 347, 9 III 2193, 9 IV 1632.]
