| production method | 348g(5mol) hydroxylamine hydrochloride, 600ml of water and 460g(4mol) n-heptanal are stirred together, sodium carbonate aqueous solution (265g sodium carbonate plus 500ml of water) is added dropwise to control the feeding speed, so that the reaction temperature does not exceed 45 ℃, the feeding is completed, and stirring is continued at room temperature for 1h. The oil layer in the reaction product was separated, distilled under reduced pressure, and the fraction at 103-107 ℃(2.13kPa) was collected to obtain 420-480g of heptyl aldehyde oxime. Yield 81%-93%. |
