ZEOLITE CATALYZED PROCESS FOR THE AMINATION OF PROPYLENE OXIDE

The present invention relates to a process for the conversion of propylene oxide to 1-amino-2- propanol and/or di(2-hydroxypropyl)amine comprising (i) providing a catalyst comprising a zeolitic material comprising YO2 and optionally comprising X2O3 in its framework structure, wherein Y is a tetravalent element and X is a trivalent element, wherein the zeolitic material has a framework-type structure selected from the group consisting of MFI and/or MEL, including MEL/MFI intergrowths; (ii) providing a mixture in the liquid phase comprising propylene oxide and ammonia; (iii) contacting the catalyst provided in (i) with the mixture in the liquid phase provided in (ii) for converting propylene oxide to 1-amino-2-propanol and/or di(2-hydroxypropyl)amine.

Synthesis of pyrrole N-derivatives from oxazolidines

Transformations of oxazolidine derivatives synthesized from industrially produced amino alcohols, aldehydes, and ketones under basic or acidic catalysis lead to the formation of N-alkyl- and N-(hydroxyalkyl)-substituted pyrroles in 19-81% yields.

Process for improving the conversion of oxazolidones to alkanolamines

There is provided a regeneration process for converting oxazolidones such as hydroxypropyloxazolidone (HPOZD) to alkanolamines such as di-isopropanolamine (DIPA) and CO2. An amine stream containing HPOZD joins a stream that includes a caustic solution. The combined stream is passed to a tank where the caustic reacts with HPOZD to convert it to DIPA and CO2. The conversion of HPOZD to DIPA and CO2 requires a ratio of at least 2 moles of hydroxide for each mole of HPOZD in the solution. The conversion reaction is carried out in a reaction vessel at a temperature above 60° C. The reaction mixture is held in a feed tank for approximately 2 hours while being constantly mixed. After the reaction is completed, the mixture is allowed to settle which results in the virtually complete separation of the amine phase (containing DIPA, and water) from the caustic phase. After an appropriate settling interval, a portion of the caustic phase is drawn from the reaction mixture as a waste/neutralization stream while the other portion of the caustic phase and a very small portion of the amine phase may be sent to a recycle tank for use in subsequent reaction steps. The majority of the amine phase is treated using ion exchange resins to remove excess cations from the amine and clean amine is returned to the amine system.
