权利人:BASF SE
摘要:The invention relates to a device for synthesis of a polymer under separation of a gaseous substance. Said device comprises a reaction chamber ( 1 ), which has a top section ( 11 ), a middle section ( 12 ) and a bottom section ( 13 ), an inlet opening ( 2 ) which is arranged in the middle section ( 12 ), a first outlet opening ( 3 ) which is arranged in the bottom section ( 13 ), a second outlet opening ( 4 ) which is arranged in the top section ( 11 ), a first return opening ( 51 ), which is arranged in the bottom section ( 13 ), a second outlet opening ( 52 ), which is arranged under the top section ( 11 ), a distribution device ( 6 ), which is arranged between the top section ( 11 ) and the middle section ( 12 ), and a removal device ( 7 ) which is arranged to be movable along the top section ( 11 ). The invention further relates to a method for synthesis of a polymer which can be carried out in said device.

权利人:BASF SE
摘要:An apparatus for synthesis of a polymer with separation of a gaseous substance comprises a reaction space having an essentially circular cylindrical upper section which is bounded by two circular faces and one shell face and has a longitudinal cylinder axis, and a lower section, an inlet orifice disposed in a circular face or the shell face of the upper section, a first outlet orifice disposed in a wall of the lower section, a second outlet orifice disposed in the shell face of the upper section opposite the first outlet orifice, and a removal device which is disposed so as to be rotatable about the longitudinal cylinder axis and is in contact with both circular faces and the shell face. This apparatus can especially be used for performance of a process including the feeding of an oligomer melt into a reaction space through an inlet orifice, the polymerization of the oligomer melt to give a polymer melt, the removal of the polymer melt from the reaction space through a first outlet orifice of the reaction space, and the removal of a gaseous substance from the reaction space through a second outlet orifice of the reaction space, wherein deposits on at least one inner wall of the reaction space are removed by a removal device and transported into the oligomer melt.

标题:Synthesis of functional polyurethanes and polyesters from biomass-derived monomers
发明人：CHANG HOCHAN; HUBER GEORGE W; DUMESIC JAMES A
权利人:WISCONSIN ALUMNI RES FOUND
摘要:A method of making polyesters and polyurethanes from biomass-derived polyols. The polyol is biomass-derived and has the structure:wherein dashed bonds are single or double bonds and R is selected from the group consisting of —OH and â•?O. Polyurethanes are made by reacting the polyol with a diisocyanate. Polyesters are made by reacting the polyol with a dicarboxylic acid.

权利人:UNIV KING FAHD PET & MINERALS
摘要:A hydrogen-bonded organic framework (HOF) and a method of making the HOF. The HOF has at least one amine substituted organic linker and at least one carboxylic acid-based organic linker. The HOF is prepared by dissolving the linkers separately in water and mixing the aqueous solutions, without using any organic solvents, additional catalysts, or any other reagents.
