Versuchsvorschrift

I have now found a novel method for producing mebutamate diol which includes the process steps of reacting crotyl alcohol and allyl chloride to produce a mixture of isomers of allyl crotyl ether, heating said crotyl ether to produce 2,3-dimethyl-pent-4en-aldehye. The aldehyde is then converted to 2-methyl-2-(sec butyl)-1, 3-propanediol by reacting 2,3-dimethyl-pent-4en-aldehyde and formaldehyde to produce 2,3-dimethyl-2-hydroxymethyl-pent-4en-ol and subsequently hydrogenating the said alcohol in the presence of a catalyst to produce 2-methyl-2-(sec butyl)-1,3-propanediol.
