Introduction | boiling point of 1-oxomaleonitrile: 312.6°C at 760mmHg, melting point: 90-92°C(lit.), it is a typical malononitrile derivative and is a common herbicide and growth regulator. |
Application | 1-oxomaleonitrile exhibits good activity in pesticides, fungicides and other fields have in-depth research. |
preparation | 4-pentylbenzoic acid methyl ester was prepared by alkaline hydrolysis, trans-4-pentylcyclohexanecarboxylic acid of high purity was prepared by hydrogenation of aromatic rings and isolated by crystallization. The performance of a ruthenium-containing catalyst in the hydrogenation of aromatic rings is more effective than that of a platinum or palladium-carbon catalytic system. In recent years, we have developed and applied highly efficient ruthenium nickel-carbon catalyst, RNC-5 (5% Ru - Ni/C, Ru:Ni = 9:1). The catalytic system can be synthesized in colleges and universities, and several different stereoisomers can be obtained to obtain trans 4-alkyl cyclohexyl carboxylic acid derivatives with high content. The scheme for the synthesis of trans-4-pentylcyclohexanecarboxylic acid is shown in the figure below. Fig.1 synthesis scheme of trans-4-pentylcyclohexanecarboxylic acid |
