The present invention relates to a process to manufacture lignin-based polyols (LBP) by ring opening polymerization (ROP) of oxiranes in the presence of lignin and in an organic solvent or mixture thereof using acidic catalysts. The LBP are suitable to manufacture polyurethanes, polycarbonates and polyesters.

Lignin-based polyols

The present invention relates to a method for continuous production of 2,3-butanediol by hydrogenation of 3-hydroxybutanone with hydrogen in the presence of a heterogeneous hydrogenation catalyst filled in one or more fixed-bed flow tubular reactor systems comprising one or more tubes with an inner diameter from 1 mm to 6 mm.

Method for continuous production of 2,3-butanediol

The present invention provides a modified strain of the bacteriumobtainable by a method that comprises a step of fusion of two protoplasts from twoparental strains which, compared to the wild type strain offrom which they derive, show: (a) an increased ability to produce acetoin and/or 2,3-butanediol (2,3-BDO), and (b) a decreased ability to produce lactic acid, when cultured under aerobic conditions, and wherein the modified strain ofhas an increased ability to produce 2,3-BDO of at least 20 times the amount produced by the wild type strain, an increased ability to produce acetoin of at least 20 times the amount produced by the wild type strain and a decreased ability to produce lactic acid of at least 10 times the amount produced by the wild type strain, when cultured under aerobic conditions. Also provided are methods to produce acetoin and 2,3-BDO.

Bacterial strain producing 2,3-butanediol and other metabolites

The invention relates to a method for obtaining glycidol in a semi-continuous or continuous manner by decarboxylating glycerol carbonate at reduced pressure, at a temperature less than or equal to 130&#xb0; C. and in the presence of alkoxide catalysts of alkaline metals and alkaline earth metals, metal oxides, mixed metal oxides, metal stannates and mixed metal stannates, all of which optionally supported via SiO, &#x3b3;-AlO, MgO and ZrO.
