Electric Literature of 1572-52-7, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1572-52-7, name is 2-Methylenepentanedinitrile, This compound has unique chemical properties. The synthetic route is as follows.
REFERENCE EXAMPLE 1 3-(3,4-Dichlorophenylthio)-2-(2-methoxycarbonylethyl)propionic acid A mixture of 3,4-dichlorobenzenethiol (3.00 ml), methyleneglutaronitrile (2.57 ml), ethanol (25 ml), and triton B (40% methanol solution, 10 drops) was refluxed for 4 hours. After the reaction mixture was concentrated in vacuo, the resulting residue was dissolved in chloroform, washed with water, and dried over MgSO4. The solvent was evaporated at reduced pressure, and the residue was recrystallized from diethyl ether-hexane to give 6.14 g of 2-(3,4-dichlorophenylthiomethyl)glutaronitrile. Melting point: 53-55 C. IR (KBr): nuCN 2240 cm-1
The chemical industry reduces the impact on the environment during synthesis 2-Methylenepentanedinitrile. I believe this compound will play a more active role in future production and life.
