The present invention relates to a composition comprising: a) at least one primary, secondary or tertiary amine and b) at least one agent which masks the odor of said at least one amine, said at least one odor-masking agent comprising at least one ether (b1), optionally, but preferably, at least one terpene and/or one terpenoid (b2) and optionally, but preferably, at least one oxime (b3). The invention also relates to the use of an odor-masking agent in order to mask the odor of at least one amine.

Odour-masked amine composition

The present invention relates to a process for preparing alkylalkanolamines, comprising the reaction of a carbonyl-based compound with a hydroxylalkylamine, in the presence of hydrogen and a catalyst.

The invention relates to the use, as neutralizing and/or co-dispersion agent in a paint and/or as agent for developing the coloring power of pigment(s) in a white paint base that we wish to color, of at least one hydroxylated secondary or tertiary amine. The invention also relates to pigment concentrates and paints containing at least one hydroxylated secondary or tertiary amine.

Neutralizing and co-dispersion agent with strong capacity for developing coloring power, and paints and pigment concentrates containing same

Disclosed herein is N-ethylmethylamine having a very high degree of purity, that is to say very low contents of impurities commonly encountered in conventional industrial processes, and a process for preparing, on an industrial scale, high-purity N-ethylmethylamine.
