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. 123-06-8, name is Ethoxymethylenemalononitrile, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: Ethoxymethylenemalononitrile
Triethylamine (9.7mL, 69.6mmol) was added to tert-butylhydrazine hydrochloride (8.67g, 69.6mmol) After adding absolute ethanol (460mL) and stirring at room temperature to dissolve, Ethoxymethylenemalononitrile (8.5 g, 69.6 mmol) was added in small portions, the solution was heated to reflux for 3 hours, and then the solvent was evaporated in vacuo to obtain a crude orange product. It was extracted with a mixed solution of ethyl acetate (0.5 L) and water (0.25 L), dried over anhydrous magnesium sulfate, and the organic layer was evaporated to obtain an orange solid. Continue to wash the obtained solid with a cyclohexane solution containing 10% ethyl acetate to obtain crystalline solid 5-amino-1-tert-butyl 1hydro-pyrazole-4-cyano 9.54g (yield 83% ).
According to the analysis of related databases, 123-06-8, the application of this compound in the production field has become more and more popular.
