Abstract: Provided is an apparatus for an aldol condensation reaction having high productivity at low cost. Specifically, the apparatus for an aldol condensation reaction according to the present invention has an effect of having high productivity by preventing a drop in a conversion rate due to an increase in a residence time when increasing a facility scale, allows conditions of raising a concentration of a catalyst and a temperature, and has an effect of minimizing a content of the catalyst used at the same yield as compared with a conventional apparatus. In addition, costs required for increasing a facility scale may be minimized without adding a device such as a pump separately, and an amount of harmful wastewater produced may be minimized.

Abstract: Systems and methods are provided for direct conversion of methane and/or ethane to methanol. The methods can include exposing methane to an oxidant, such as O2, in a solvent at conditions that are supercritical for the solvent while having a temperature of 310° C. or less, or about 300° C. or less, or about 290° C. or less. The solvent can correspond to an electron donor solvent that, when in a supercritical state, can complex with O2. By forming a complex with the O2, the supercritical electron donor solvent can facilitate conversion of alkane to methanol at short residence times while reducing or minimizing further oxidation of the methanol to other products.

Abstract: Flow control mechanisms control the direction and flow rate of synthesis reagent through one or more synthesis reaction vessels for automated solid phase synthesis. Selectable, known, and reproducible positive or negative pressure differentials (−5 to +10 psi) accomplish controlled, bidirectional (forward and reverse) flow of synthesis reagents through synthesis media contained within the reaction vessels. Venturi-based vacuum apparatus, valves, electronic pressure regulators and compound digital pressure gauge, can be added to automated solid phase synthesis instruments to provide, control, and monitor known, selectable, reproducible negative and positive pressures to one or both valve sealable and un-sealable ends (inlets and outlets) of the reaction vessel as needed to generate and reverse said pressure differentials between the opposite ends of said synthesis reaction vessels, yielding controlled forward and backward flows of synthesis reagents through the synthesis media.

Abstract: A method and a device for manufacturing lactide, whereby crude lactide, being prepared by means of depolymerization of lactic acid oligomers, is purified by means of a distillation step. The prepared crude lactide is maintained for a period of at least 5 hours in a reaction vessel at a temperature between 97° C. and 200° C. prior to the distillation step. Keeping the lactide during a period of time in a reaction vessel leads to a decrease of the lactic acid content and an increase of the lactic acid oligomer concentration, so that the resulting crude lactide can be more efficiently purified during subsequent distillation. A pre-distilling step gives additional advantages.
