Yield:513-42-8 1400 g ,123-39-7 1080 g
Reaction Conditions:
with aluminum oxide at 3 - 10;Large scale;
Steps:
3 Preparation of Methylallyl alcohol and N-methylformamide
into a 5L reaction flask, stirring, add 2000 g of methallyl formate, add 90 g of basic aluminiumoxide, cooled at 5° C. Slowly pass through methylamine gas, the reaction temperature is controlled at about 3-10 ° C. pass through about 350g methylamine , gas phase detection of methallyl basic consumption. Stop the reaction. Atmospheric distillation to collect 114 ° C fraction, that is Methylallyl alcohol 1400g. Decompression distillation and then collected 1080g of N-methyl formamide fraction.
