3,4-二甲基戊醛

反应条件: temp:70.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Dibutylamine (34 g), acetic acid (15.78 g), and formaldehyde (230 g) were charged to a reaction flask and heated to 70° C. 3,4-Dimethyl-pentanal (500 g) was fed over 2 hours and aged for another hour. The reaction mixture was cooled down and toluene (200 mL) was added. The reaction mixture was sequentially washed with water (2 L), sodium carbonate solution (1 L), and brine (1 L) to provide the crude product 3,4-dimethyl-2-methylene-pentanal. aged for another hour The reaction mixture was cooled down The reaction mixture was sequentially washed with water (2 L), sodium carbonate solution (1 L), and brine (1 L)
