Reaction Conditions:
Stage #1: formaldehyd;2-(2-Aminoethoxy)ethanol for 0.5 h;
Stage #2: with formic acid at 100 - 110; under 705.071 Torr; for 2 h;
Stage #3: with butan-1-ol at 120; for 4 h;Reagent/catalyst;Temperature;
Steps:
Example 1 A DMAEE synthesis method comprising the steps of: diethylene glycolamine, paraformaldehyde and formic acid as starting materials,
1). Synthesis To a 250 ml three-necked flask were added 63.1 g of diethylene glycol amine (0.6 mol), 34.5 g of paraformaldehyde (1.2 mol), stirred for 30 minutes,63 g of formic acid (1.2 mol, 88%) was added dropwise at a temperature of 100 to 110 ° C, and the reaction was carried out at about 100 ° C for 1 hour. 30 g (vacuum - 0.094 MPa, kettle temperature 80 ° C) was distilled off under reduced pressure. The end of steaming,The product content was 90.0% and the impurity (S-2) content was 9.8%. _: The step 2) of the liquid to transfer to 500 ml distillation flask in the vacuum degree is -0.094 mpa under reduced pressure distillation, 62 °C component is a normal butanol ester exchange down of the formic acid is ding Chunzhi, 121 °C DMAEE component namely the products. Collecting 121 °C component 128.3g, yield 96.5%, content of 99.9%.
