Methylaminoacetaldehyde dimethyl acetal synthesis
- Product Name:Methylaminoacetaldehyde dimethyl acetal
- CAS Number:122-07-6
- Molecular formula:C5H13NO2
- Molecular Weight:119.16
Yield:122-07-6 87%
Reaction Conditions:
in water at 80 - 85; for 16 h;Autoclave;
Steps:
1.1; 2.1; 3.1 Example 3:
In the first step, in the 1L autoclave,Add 249g of chloroacetaldehyde dimethylacetal and 117g of water,Then 218g of monomethylamine gas was introduced, the stirring was turned on, the temperature was raised to 80-85°C, and the reaction was carried out for 16 hours.GC detects that the raw material is less than ≦0.5percent, and the temperature is reduced and the pressure is reduced to about 20°C.Add 100g of dichloromethane each time, extract 3 times,Combine the organic phases, first evaporate the solvent, and then distill 207g of the product under reduced pressure.The GC content is 96percent, and the yield is 87percent.
