Document Type and Number:
WIPO Patent Application WO/2021/114166
Kind Code:
A1
Abstract:
A process for preparing a N-substituted alkanolamine of formula (I) and/or a N-substituted diamine of formula (II) from glycolaldehyde is provided, which comprises reacting glycolaldehyde with an aminating agent of formula (III) in a solvent comprising at least one C1-C3 alkanol and/or tetrahydrofuran in the presence of hydrogen and a supported noble metal catalyst, wherein in formulas (I) - (III) : R and R', independently from each other, represent hydrogen, linear or branched C1-C20 alkyl, C3-C12 cycloalkyl, C2-C30 alkoxyalkyl, or C3-30 dialkylaminoalkyl, provided that at least one of R and R' is not hydrogen.
