| Application | 2-propanol pyridine is an organic intermediate, which can be achieved by the reaction of 2-ethylpyridine and paraformaldehyde, or by 3-(2-Pyridyl)-2-propylene-1-ol is obtained by hydrogen reduction. |
| Preparation | In a 3-liter stainless steel autoclave, 1070 grams (10 mol) of 2-ethylpyridine is added relative to 300 grams of ion-exchanged water, and 60 grams (2.0 mol) of paraformaldehyde and 81 grams (0.8 mol, pKb = 3.3) are added and reacted at 140°C for 2 hours. 0.4 moles of triethylamine relative to 1 mole of paraformaldehyde. Remove paraformaldehyde and triethylamine from the reaction solution at 60°C, below 25kPa, and then at 120°C, below 2kPa, and recover water and unreacted 2-ethylpyridine. The resulting concentrate 247g was determined to be 2-propanol pyridine by 1H-NMR analysis. |
