USPTO Patent Grant: Process for Ethyleneamines and Ethanolamines Manufacture
Summary
The USPTO has granted patent US12583827B2 to BASF SE for a new process to manufacture ethyleneamines and ethanolamines. The patent details a two-step process involving the conversion of glycolaldehyde derivatives and an aminating agent, followed by hydrogenation.
What changed
USPTO Patent Grant US12583827B2, assigned to BASF SE, details a novel process for manufacturing ethyleneamines and ethanolamines. The patent describes a two-step method: first, converting a glycolaldehyde derivative with an aminating agent in either gas or liquid phase; second, hydrogenating the resulting reaction products in the presence of a catalyst. This grant provides exclusive rights for this specific chemical manufacturing process.
While this is a patent grant and not a regulatory rule imposing direct compliance obligations on other entities, companies involved in the production of ethyleneamines and ethanolamines should be aware of this granted patent. Competitors may need to ensure their manufacturing processes do not infringe on the claims of this patent, potentially requiring review of their own chemical synthesis methods and seeking alternative, non-infringing processes if necessary.

Abstract
A process for the manufacture of ethyleneamines and ethanolamines, comprising the steps of (i) converting a glycolaldehyde derivative of formula (II), in which R2, R3 are—the same or different—hydrogen, alkyl, such as C1-6-alkyl, or cycloalkyl such as Cs-e-cycloalkyl; and an animating agent of formula (III); in which R1 is hydrogen (H), alkyl, such as C1-6-alkyl, or cycloalkyl such as C3-6-cycloalkyl, in the gas or liquid phase; (ii) feeding the reaction products obtained in step (i) into a hydrogenation reactor, where the reaction products are converted with hydrogen in the presence of a hydrogenation catalyst.
