<p>NEW MATERIAL:A basic compound shown by the formula I (X is H, 1-4C alkyl, halogen, and nitro; m and n are 1-4). EXAMPLE:1,8-Diamino-N<3>-[2-(para-n-butyl)ethyl]-3,6-diaza-n-octane. USE:A curing agent for an epoxy resin, etc. PROCESS:An amine (e.g., diethylenetriamine, etc.) shown by the formula II is reacted with a substituted styrene (e.g., styrene, chlorostyrene, etc.) in the presence of an alkali metal amide (e.g., lithium amide, etc.) to give a compound shown by the formula I. The reaction is carried out by using an inert organic solvent (e.g., hexane, cyclohexane, tetrahydrofurane, etc.). A compound shown by the formula III has catalytic action and its concentration influences the reaction rate.</p> |
