    Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound by reaction between an α,β-unsaturated nitrile and an alcohol using a specific diazabicycloalkene as basic catalyst without the need of any prior separation or neutralization of the catalyst for the addition reaction.
    SOLUTION: This compound is obtained by reaction between an α,β-unsaturated nitrile (e.g. acrylonitrile) and a monohydric, dihydric or trihydric alcohol (e.g. methanol, ethanol, 2-ethylhexanol, 2-methoxyethanol, benzyl alcohol) at -20 to 200°C using a diazabicycloalkene of the formula (H may be substituted with a 1-20C alkyl, 6-20C aryl or 7-20C arylalkyl; (n) and (m) are each 1-6) as basic catalyst {e.g. 1,5-diazabicyclo[4.3.0]nonene-5(DBN), 1,8- diazabicyclo[5.4.0]undecene-7(DBU)}; wherein the amount of the catalyst to be used is pref. 0.05-5 wt.% based on the alcohol.

    Abstract: PROBLEM TO BE SOLVED: To economically and continuously obtain an alkylamine in a simplified apparatus by preheating only an amine stream or only an aldehyde stream fed by separated stream during feed and reacting the amine with the aldehyde on a fixed bed catalyst in a reactor. SOLUTION: Only an aldehyde stream [e.g. formaldehyde aqueous solution having 50-90 wt.%, preferably 65-75 wt.% water content based on total weight of the solution] or only an amine stream (preferably 30-80 wt.% piperazine aqueous solution) fed by separated stream is preheated during a feed (a molar ratio of piperazine to formaldehyde is 1:1.0 to 1:5, preferably 1:2 to 1:2.7) is and the aldehyde is reacted with the amine in a reactor in which these compounds are mixed in a catalyst bed on a fixed bed catalyst in the presence of an isolated hydrogen to continuously provide the objective alkylamine.

    Abstract: PROBLEM TO BE SOLVED: To industrially and economically advantageously N-alkylate an amine by carrying out the reaction in the presence of a specific catalyst. SOLUTION: When (A) an alcohol (preferably an α,ω-diol) is reacted with (B) an alkylamine or a dialkylamine (preferably monomethylamine, etc.), the reaction is carried out in the presence of (C) a catalyst prepared by including 0-2 wt.% BaO, Cr2 O3 and/or ZnO in copper and magnesium silicate as a base regardless thereof for each time as the catalyst. The component C preferably contains 30-60 wt.% CuO and has preferably at least 100 m /g BET specific surface area. The reaction is preferably conducted in the liquid phase under 50-300 bars pressure.
