    Abstract: The present invention provides methods for making N-methylpyrrolidine and analogous compounds via hydrogenation. Novel catalysts for this process, and novel conditions/yields are also described. Other process improvements may include extraction and hydrolysis steps. Some preferred reactions take place in the aqueous phase. Starting materials for making N-methylpyrmlidine may include succinic acid. N-methylsuccinimide, and their analogs.

    Abstract: The invention provides a method of producing a pyrrolidinone comprising:
    providing an initial aqueous solution into a first reactor, the solution comprising ammonia and comprising an initial compound having formula (A);

    where R 1 is selected from the group consisting of branched and un-branched hydrocarbons having from 1 to 10 carbons, the initial solution having a first ratio of ammonia to the initial compound;
    adjusting the ratio of ammonia to produce a solution having a second ratio of ammonia relative to the initial compound of from 1:1 to 1.5:1;
    cyclizing the initial compound to form a compound having the formula (B)

    performing a purification step to produce a purified form of compound (B);
    providing the purified form of compound (B) to a second reactor; and
    in the presence of a catalyst, hydrogenating the purified compound (B) to produce a pyrrolidinone compound having formula (C)
