The invention relates to a method for obtaining acetoin from a medium containing same, the method comprising a step of dehydration by pervaporation using a hydrophilic membrane. With this method, the acetoin can be satisfactorily isolated and purified, both in terms of quality and yield. Furthermore, with the method of the invention it is possible to dispense with the use of solvents and prevent impurities from being generated.

Various aspects of this disclosure relate to the discovery that converting a solid or a liquid into an aerosol allows the distillation of molecules from the aerosol in seconds at temperatures that are significantly less than the boiling points of the molecules. Various aspects of this disclosure relate to the discovery that mute plants can be extracted at both ambient temperatures and temperatures significantly less than the boiling points of the volatile molecules of the mute plants by capturing the volatile molecules in a solvent such as ethanol.

The present invention relates to a method for thermolytic fragmentation of a sugar into C1-C3 oxygenates, comprising cooling the fragmentation product downstream of the reactor to a cooling temperature of from 230 C. to 390 C. and then separating solids from the fragmentation product cooled to the cooling temperature. The present invention also relates to a system for performing the thermolytic fragmentation of a sugar into C1-C3 oxygenates. The method and the system are suitable for industrial scale production.

A process for producing an aldehyde is disclosed. The process comprises: hydroformylating an olefin to form the aldehyde using a hydroformylation catalyst; recovering an effluent stream comprising the aldehyde, hydrogen and the hydroformylation catalyst; passing the effluent stream to a stripper; contacting the effluent stream with a strip gas in the stripper to produce a stripped effluent stream having a lower hydrogen concentration than the effluent stream; and recovering the stripped effluent stream.

A method for preparing an aldehyde including: reacting reactants in a reactor to obtain a reaction product; supplying the reaction product to a first flash drum, performing gas-liquid separation, and supplying a liquid separated product to a vaporization part including a vaporizer; vaporizing the liquid from the vaporization part separate-into a vapor stream and a liquid stream; supplying the vapor stream to a second flash drum to separate an upper discharge stream and a lower discharge stream from the second flash drum; and supplying the upper discharge stream from the second flash drum to one or more flash drums, and supplying the lower discharge stream from the second flash drum to a distillation tower and performing distillation to obtain the aldehyde from a lower discharge stream from the distillation tower, wherein a ratio of an operating temperature of the vaporizer to a reaction temperature of the reactor is controlled.
