反応条件: temp:0.00; pressure:0.00; stir:

反応条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Heptane (394 mL) and morpholine (127.5 mL) are introduced in a reactor while stirring. The mixture is cooled to 0° C. and glyoxylic acid (195 g, 150 mL, 50 wt % in water) is added. The mixture is heated to 20° C. during 1 hour and then n-valeraldehyde (148.8 mL) is added. The reaction mixture is heated at 45° C. during 20 hours. After cooling down to 20° C., a 37% aqueous solution of hydrochloric acid (196.9 mL) is slowly added to the mixture, which is then stirred during 2 hours. The mixture is heated to 20° C. during 1 hour The reaction mixture is heated at 45° C. during 20 hours After cooling down to 20° C. is then stirred during 2 hours
