By2-methyl-2-pentenal is obtained by catalytic hydrogenation2-methylvaleral, then This product is prepared by hydroxymethylation and reduction reaction with formaldehyde. 2-Methyl-2-pentenal hydrogenation reaction100℃,1.3-1.5MPaProceed as follows, yield80%. Get2-After adding methylvaleral, add it36% In formaldehyde, add sodium hydroxide solution dropwise at room temperature. The reaction releases heat and naturally heats up to 70℃, then heat to 90 ℃, add flow1h, cool to60℃ and let stand for layering. The upper liquid is washed with water. The washing liquid and the lower liquid are combined and extracted with benzene. Combine the extract and the supernatant, distill to recover benzene, then perform vacuum distillation and collect160℃（14.7kPa) fraction, that is for2-Methyl-2-propyl-1,3-Propylene glycol, Yield93%.

Purpose

for organic synthesis . Intermediate of the weak tranquillizer amethylpropane.
