The present invention relates to a process for preparing deodorized 1,2-propanediol, to the use of the purified propanediol and to an apparatus for performing the process.

Process for preparing deodorized 1,2-propanediol

Method for producing deodorized 1,2-propanediol

The present invention relates to a process for preparing 1,2-propanediol, in which a glycerol-containing stream, especially a stream obtained on the industrial scale in the production of biodiesel, is subjected to a hydrogenation in an at least three-stage reactor cascade.

Method for producing 1,2-propandiol by hydrogenation in at least three successive reactors

The present invention relates to a process for preparing 1,2-propanediol, in which a glycerol-containing stream, especially a stream obtained on the industrial scale in the production of biodiesel, is subjected to a low pressure hydrogenation.

Method for producing 1,2-propandiol by low-pressure hydrogenation of glycerine

The present invention relates to a process for preparing 1,2-propanediol, in which a glycerol-containing stream, especially a stream obtained on the industrial scale in the production of biodiesel, is subjected to a hydrogenation in a two-stage reactor cascade.

Method for producing 1,2-propandiol by hydrogenating glycerine in a two-step reactor cascade

The present invention relates to a process for the preparation of 1,2-propanediol, in which a glycerol-containing stream, in particular a stream obtained on an industrial scale in the production of biodiesel, is subjected to a hydrogenation.
