Abstract: N-alkylated derivatives of 2-amino-2-hydrocarbylthiomethyl-11,3-propanediols, useful as flotation agents, rubber modifiers, and chelating agents in the separation of metals, are produced by reacting 2-amino-2-hydrocarbylthiomethyl-1,3-propanediols with organic halides. Thiols can be produced by reacting arylmethylated or alkarylmethylated derivatives of the above compounds with an alkali metal in the presence of ammonia.
