| titleOfInvention | Method for preparing trimethylolpropane |
| abstract | The present invention relates to a method for producing trimethylolpropane (TMP), 1) trimethylolpropane through an aldol condensation reaction and a Carnizzaro reaction using a normal butyl aldehyde, aqueous formaldehyde and aqueous alkali metal hydroxide solution Synthesizing; 2) extracting trimethylolpropane by contacting the mixture obtained as a result of step 1 with an alcohol having 6 to 10 carbon atoms; 3) removing alkali metal ions by contacting the extract obtained as a result of step 2 with water; And 4) distilling the trimethylolpropane-containing extract from which alkali metal ions have been removed as a result of step 3). According to the present invention, a separate formaldehyde recovery step can be omitted, and while using a relatively small amount of the extraction solvent can maximize the TMP extraction efficiency, and do not use a mixed solvent for TMP extraction of the extraction solvent Separation and recovery processes can be simplified, and TMP yield can be maximized while minimizing waste water generation, thereby producing TMP with economical efficiency. |
