Yield:2917-78-4 16998 g
Reaction Conditions:
at 20; for 2 h;Large scale;
Steps:
3
Into the reactor in the compound 15000gA, 160gNi (CO) 4 / PdC (90/10) 6400g of methanol and, with stirring, was blown from the bottom of the reaction vessel 12000g monoxide; at room temperature, the reaction 2 hours. (In the course of the reaction may be employed, sodium dihydrogen phosphate / sodium phosphate buffering system to control the PH of the reaction system is 8 or less, may also be added such as sodium methoxide or sodium hydroxide to control the PH of the reaction system is 8 or less.) after completion of the reaction, the product was filtered to remove insoluble solid material system, distillation under reduced pressure to obtain 16998g product.
