| use | organic synthesis intermediate. |
| production method | add 194g pentyl -4-keto acid, 500ml 35% methylamine and 10g skeleton nickel into the autoclave. Closed, hydrogen to 7-14MPa. Stir and heat to 140 ℃ for 5 hours. After the reaction is completed, cool, take out the reactants, and filter out the catalyst. The filtrate was distilled and the 84-86 ℃(1.73kPa) fraction was collected to obtain 1,5-dimethyl-2-pyrrolidone. Yield 74-77%. |
