| Use | This product is a pesticide intermediate, used to synthesize the pesticide phosphamine intermediate α,α-dichloro-N,N-Diethylacetylacetamide. Pesticide intermediate, mainly used to prepare pesticide phosphamine. |
| production method | put the quantitative diethylamine into the reaction pot. Starting stirring, diketene is added dropwise at 40-45 ℃. After addition, keep the temperature at 45±5 ℃ for 1h to obtain acetoacetyl diethylamine with purity above 92%. The ingredient ratio (molar ratio) is diketene: diethylamine = 1:1.05. Raw material consumption quota: diethylamine (95%)478 kg/t, diketene (92%)525 kg/t. The preparation method is obtained by condensation of diethylene ketone and diethylamine. According to the feed ratio of diethylenone: diethylamine = 1: 1.05 (molar ratio), put the quantitative diethylamine into the reaction pot, start stirring, and add diethylenone dropwise at 40~45 ℃. After addition, keep the temperature at (45±5)℃ for 1h to obtain acetoacetyl diethylamine with a content of more than 92%. |
