| titleOfInvention | Novel method for preparing tri (3, 6-dioxaheptyl) amine |
| abstract | The invention relates to a novel method for preparing tri (3, 6-dioxaheptyl) amine, which takes ammonia water, diethylene glycol monomethyl ether and thionyl chloride as raw materials to synthesize the tri (3, 6-dioxaheptyl) amine through three steps. The method has mild reaction conditions and safe operation, and avoids the danger of using high-risk chemicals such as hydrogen and Raney nickel; the reaction conversion rate is high, and the product yield is high; only products, sodium chloride and a very small amount of distillate before rectification are produced in the process, excessive materials can be recycled after treatment, three wastes are very little, and the production process is green and environment-friendly. |
