Abstract: The invention discloses a method for purifying adipic acid by crystallization or recrystallization in at least one carbolyxic acid. More precisely, it discloses an improvement in adipic acid crystallization or recrystallization, characterised in that the said crystallization or recrystallization is effected in at least one carboxylic acid with a melting point below 20° C. The presence of carbon monoxide during crystallization or recrystallization can have a favourable effect on the adipic acid purity, in particular by reducing the content of metal catalyst traces of the adipic acid. The adipic acid purity can also be improved when the crystallization or recrystallization is effected in presence of a strong proton acid.

Abstract: The invention concerns a method for regenerating a hydrogenation catalyst, and hydrogenation methods carried out with a catalyst comprising at least one regenerated catalyst. More particularly, it concerns a method for regenerating Raney catalysts used in total or partial hydrogenating processes of compounds comprising nitrile functions into amine functions. Said method consists in treating the spent catalyst with a basic solution and optionally in subjecting said catalyst to hydrogenation before stripping to eliminate the impurities present on the catalyst. Thus, the regenerating method enables to recuperate up to 100% of the catalytic activity.

Abstract: A new process for the production of APMMEA (aminopropylmethylethanolamine) is proposed. This process comprises at least 2 steps in which MEAPN (monomethylethanolaminopropionitrile) is first produced from MMEA (monomethylethanol amine) and ACN (acrylonitrile) and then said MEAPN is hydrogenated to obtain the corresponding amine, the APMMEA compound. APMMEA may be then eventually purified by several known process, notably by distillation.
