1. A process for converting glycerol to acetol with high selectivity, comprising the steps of:

  • (a) contacting a glycerol-containing material with a catalyst that is capable of hydrogenating glycerol, in order to form a reaction mixture;

    (b) reacting the reaction mixture under a first condition for reaction to dehydrate the glycerol with resultant formation of acetol as a main component of a first reaction product, said first condition including a temperature within a range from 150°

    C. to 250°

    C. and a pressure within a range from 0.02 bar to 25 bar;

    (c) separating the acetol formed in step (b) from other components in the first reaction product;

    (d) reacting the separated acetol from step (c) to form a second reaction product.
