Yield:32327-90-5 98.3%
Reaction Conditions:
with formic acid in 5,5-dimethyl-1,3-cyclohexadiene at 130 - 135; for 5 h;Inert atmosphere;
Steps:
1
Add 155g of triacetone amine into the 2L reactor,68g of dimethylamine, 110g of formic acid and 330g of xylene,Under the protection of nitrogen, start stirring and raise the temperature to 130135. After 5 hours,Sampling and testing are qualified, the reaction solution is reduced to room temperature,Wash with sodium hydroxide aqueous solution (30%, wt.) and deionized water to weakly alkaline,Negative pressure distillation obtains the compound represented by the intermediate formula IV with a yield of 98.3%.
