Description

Verfahren zur Herstellung von Succinimid Es wurde die überraschende Beobachtung gemacht, daß man in einfacher Weise zum Succinimid gelangt, wenn man auf Acrylsäurenitril in wässieriger Lösung ein Alkalicyanid einwirken läßt. Die Umsetzung nimmt man zweckmäßig bei erhöhter Temperatur vor. Das Succinimid kann aus dem Umsletzungsgemisch leicht abgetrennt werden, z. B. durch Abdestillieren.Method of making succinimide It has been found to be surprising Observation made that one arrives at the succinimide in a simple manner if one allows an alkali metal cyanide to act on acrylonitrile in aqueous solution. the The reaction is expediently carried out at an elevated temperature. The succinimide can easily separated from the reaction mixture, e.g. B. by distilling off.

Man kann auch auf -eine Abtrennung des Succinimids verzichten und die Reaktionslösung z. B. durch Verseifen unmittelbar auf Bernsteinsäure verarbeiten. Erhitzt man die Mischung mit einem Alkohol und mit Säure, dann kann man unmittelbar zu den Estern der Bernsteinsäure gelangen.You can also do without a separation of the succinimide and the reaction solution z. B. process directly to succinic acid by saponification. If you heat the mixture with an alcohol and with an acid, then you can immediately get to the esters of succinic acid.

Beispiel i 57 Gewichtsteile Acrylsäurenitril werden mit 5oGewichtsteilen-Natriumcyanid oder 65Gewichtsteilen Kaliumcyanid in i 5o Gewichtsteilen Wasser auf So' erwärmt. Nach be- endigter Umsetzung wird das Lösungsmittel im Vakuum entfernt, die entstandene Kalilauge mit 'Schwefelsäure in Methanol abgetrennt und das Succinimid im Vakuum destilliert.Example i 57 parts by weight of acrylonitrile are heated to 50 parts by weight of sodium cyanide or 65 parts by weight of potassium cyanide in 150 parts by weight of water. After loading endigter reaction, the solvent is removed in vacuo, the resulting potassium hydroxide solution is separated with 'sulfuric acid in methanol and the succinimide was distilled in vacuo.

Beispiel 2 57 Gewichtsteile Acrylsäurenitril werden mit 5o Gewichtsteilen Natriumcyanid oder 65 Gewichtsteilen Kaliumcyanid in 15o Gewichtsteilen Wasser io bis 12 Stunden auf ioo° erhitzt und das Umsetzungsprodukt mit Schwefelsäure zu Bernsteinsäure verseift.Example 2 57 parts by weight of acrylonitrile are 50 parts by weight Sodium cyanide or 65 parts by weight of potassium cyanide in 150 parts by weight of water io heated to 100 ° for up to 12 hours and the reaction product with sulfuric acid to succinic acid saponified.

Ausbeute: etwa 700/0.Yield: about 700/0.
