摘要： A process for producing polyols (such as neopentyl glycol) is disclosed which comprises reacting formaldehyde and another aldehyde in the presence of a trialkylamine catalyst and a base promoter to form an Aldol condensation reaction product. The base promoter improves removal of nitrogen containing salts prior to hydrogenation of the hydroxy aldehyde to produce the polyol. The improved process also reduces trialkylamine catalyst usage, improves trialkylamine catalyst recovery, and reduces nitrogen-containing salts prior to hydrogenation.

摘要： A multistage tubular reaction system and method for preparing methylol derivatives of an aldehyde includes a tubular reaction system with a plurality of successive reactor stages comprising a plurality of jacketed reaction tubes provided with a cooling system adapted to control flow of a cooling medium through said jacketed reaction tubes. The cooling medium flow is controlled independently in different stages in response to temperature measurements in the reaction system to regulate temperature. In order to further reduce temperature spikes and byproduct generation, aldehyde is stepwise added to the production stream at a plurality of feed ports proximate to reaction tubes equipped with tube inserts to enhance mixing and heat transfer.

摘要： The present invention provides a method for producing ditrimethylolpropane including reacting n-butyraldehyde with formaldehyde in the presence of a base catalyst to thereby produce trimethylolpropane and ditrimethylolpropane, wherein the method includes (I) a step of reacting n-butyraldehyde with formaldehyde (1) in the presence of a base catalyst (1), to thereby produce a reaction mixture containing trimethylolpropane, ditrimethylolpropane, and 2-ethyl-2-propenal; (II) a step of recovering 2-ethyl-2-propenal through distillation of the produced reaction mixture; and (III) a step of adding, to a distillation residue obtained through recovery of 2-ethyl-2-propenal, the recovered 2-ethyl-2-propenal and formaldehyde (2), and optionally a base catalyst (2), to thereby allow reaction for production of ditrimethylolpropane to proceed, wherein the amounts of formaldehyde (I) and the base catalyst (1) supplied in step I and formaldehyde (2) and the base catalyst (2) supplied in step II are controlled to specific amounts, to thereby effectively produce ditrimethylolpropane. According to the present invention, the yield of di-TMP is considerably increased, and the amount of bis-TMP by-produced can be considerably reduced with respect to the amount of di-TMP (i.e., a product of interest) produced; that is, di-TMP can be effectively produced in an industrially advantageous manner.

摘要： The present invention relates to a method for preparing trimethylolpropane (TMP) comprising the steps of: 1) synthesizing trimethylolpropane by using n-butyl aldehyde, an aqueous solution of formaldehyde and an aqueous solution of alkali metal hydroxide through aldol condensation reaction and Cannizzaro reaction; 2) extracting trimethylolpropane from a resultant mixture of the step 1) by contacting the resultant mixture with an alcohol having 6 to 10 carbons; 3) removing alkali metal ion from a resultant extract of the step 2) by contacting the resultant extract with water; and 4) distilling the alkali metal ion-removed extract obtained from the step 3). According to the present invention, a separate formaldehyde recovery process can be omitted, the extraction efficiency of TMP can be maximized with using a relatively small amount of extraction solvent, the separation and recovery processes for extraction solvent can be simplified since a mixture of solvents is not used for TMP extraction, and the yield of TMP can be maximized while the amount of generated waste water can be minimized, thereby producing TMP economically with good efficiency.
