Description
Verfahren zur Darstellung oxyalkylierter (y Alkoxy-ß-oxypropyl)-aminobenzole Durch das Patent 6o3 8o8 ist ein Verfahren zur Darstellung oxyäthylierter (y-Alkoxy-13-oxypropyl)-aminobenzole durch Behandlung von y-Alkyläthern der (ß, y-Dioxypropyl)-aminobenzole mit Äthylenoxyd unter Druck bei erhöhter Temperatur geschützt.Process for the preparation of oxyalkylated (γ-alkoxy-ß-oxypropyl) aminobenzenes Patent 6o3 8o8 describes a process for the preparation of oxyethylated (γ-alkoxy-13-oxypropyl) aminobenzenes by treating γ-alkyl ethers of (ß, γ-dioxypropyl) aminobenzenes with ethylene oxide protected under pressure at elevated temperature.
Es wurde nun weiter gefunden, daß sich auch Propylenoxyd und Butylenoxyd für dieses Verfahren anwenden lassen, wobei man die entsprechenden oxyalkylierten (y-Alkoxyp'-oxypropyl)-aminobenzole erhält. An Stelle der reinen Alkylenoxyde kann man auch ihre technischen Gemische, wie sie bei der Herstellung anfallen, benutzen; es entstehen dann Gemische oxyalkylierter Körper der erwähnten Art. Die erhaltenen Körper sind ebenfalls wertvolle Zwischenprodukte für Farbstoffe. Beispiel i 163 Teile (y-Methoxy-ß-oxypropylainino)-benzol werden mit 66 Teilen eines technischen Gemisches von Butylenoxyden 6 Stunden lang unter Druck auf iyo bis i8o' erhitzt. Man ,destilliert das entstehende C51 im Vakuum und erhält 165 Teile des Oxybutyl- (y-methoxyß-oxypropylamino) -benzols vom Kpio 2o5 bis 2o8°.It has now been found that propylene oxide and butylene oxide can also be used for this process, the corresponding oxyalkylated (γ-alkoxyp'-oxypropyl) aminobenzenes being obtained. Instead of the pure alkylene oxides, it is also possible to use their technical mixtures, such as those obtained during manufacture; mixtures of oxyalkylated bodies of the type mentioned are then formed. The bodies obtained are also valuable intermediate products for dyes. EXAMPLE I 163 parts of (γ-methoxy-β-oxypropylainino) -benzene are heated with 66 parts of a technical mixture of butylene oxides for 6 hours under pressure to iyo to i8o '. The resulting C51 is distilled in vacuo and 165 parts of oxybutyl- (γ-methoxyβ-oxypropylamino) benzene with a boiling point of 2o5 to 2o8 ° are obtained.
Beispiel 2 z29,3 Teile 3-Chlor-i-(y-methoxy-ß-oxypropylamino)-benzol werden mit 38,4. Teilen reinem Propylenoxyd (Kp.350) q. Stunden auf i8o bis igo0, dann 2 Stunden auf 2oo0 im geschlossenen Rohr erhitzt. Man destilliert das entstandene C)1 im Vakuum und erhält 156 Teile 3-Chlor-i-(y-methoxy-ß-oxypropyloxypropylamino) -benzol vom Kpio 2260.Example 2 z29.3 parts of 3-chloro-i- (γ-methoxy-β-oxypropylamino) -benzene become with 38.4. Parts of pure propylene oxide (boiling point 350) q. Hours on i8o to igo0, then heated to 2oo0 for 2 hours in a closed tube. The resulting one is distilled C) 1 in vacuo and receives 156 parts of 3-chloro-i- (y-methoxy-ß-oxypropyloxypropylamino) -benzene from Kpio 2260.
Beispiel 3 86 Teile (y-Methoxy-ß-oxypropylamino)-benzol werden mit 38 Teilen Isobutylenoxyd (KP- 50 bis 520) q. Stunden auf i8o bis igo0 und 2 Stunden auf 2oo° im geschlossenen Rohr erhitzt. Das Reaktionsprodukt wird im Vakuum destilliert, wobei 88 Teile Oxyisobutyl- (y-methoxy-ß-oxypropylamino) -benzol erhalten werden (KP, e050).Example 3 86 parts of (γ-methoxy-β-oxypropylamino) benzene are mixed with 38 parts of isobutylene oxide (KP- 50 to 520) q. Heated to 180 to igo0 hours and 2 hours to 2oo ° in a closed tube. The reaction product is distilled in vacuo, 88 parts of oxyisobutyl (γ-methoxy-β-oxypropylamino) benzene being obtained (KP, e050).
