摘要： Provided is a method for recovering a carboxylic acid, by which method the carboxylic acid is separated from an aqueous solution containing water and the carboxylic acid and the separated carboxylic acid is obtained as a carboxylic acid anhydride. The method includes a) a first step of bringing the aqueous solution into liquid-liquid contact with a prepared extractant, the prepared extractant containing a component for extracting the carboxylic acid and a diluent to dissolve the component, b) a second step of distilling the prepared extractant that is subjected to the first step, azeotropically distilling the diluent in the prepared extractant and water, separating the distillate into an extractant component layer mainly containing the diluent and an aqueous layer and then discharging the aqueous layer, returning the extractant component layer mainly containing the diluent to the distillation step as reflux, and discharging the prepared extractant containing the carboxylic acid through a bottom of the column; and c) a third step comprising re-distilling the prepared extractant containing the carboxylic acid discharged by the second step, and returning, to the first step, the prepared extractant from which the carboxylic acid and water are removed, the prepared extractant being discharged through a bottom of the column, where the diluent in the prepared extractant have a minimum boiling azeotrope with water.

摘要： A co-salt of a polyunsaturated fatty acid and a non-fatty acid is formed as a precipitate. The co-salt formed is free flowing and does not tend to agglomerate (cake) in storage. The resultant co-salt product will be easy to blend with other products to produce dietary supplements. These novel co-salt products may also tablet very well and may be added to current dietary supplement tablets.

摘要： A compound synthetic pathway is generated without limiting chemical conversion rules. A synthetic pathway generating apparatus includes: a converting unit to convert chemical structures of compounds into numerical values; a calculation unit to create a compound pair and to calculate a difference value by subtracting the numerical value of one compound of the compound pair from the numerical value of the other compound thereof; a determining unit to compare the difference value of the compound pair of the reaction between which is already known with the difference value of the compound pair of the reaction between which is unknown, and to determine unknown reactions of the compound pairs with the difference values being coincident as virtual reactions; a generating unit to generate compound synthetic pathways by use of nodes representing the compounds and edges representing the known reaction and the virtual reaction respectively; and a selecting unit to select a synthetic pathway from a starting compound to a target compound out of the generated compound synthetic pathways.
