| titleOfInvention | Synthetic method for 2,6-dimethy-5-heptenal |
| abstract | The invention discloses a synthesizing method of 2, 6-dimethyl-5-heptene aldehyde, which comprises the following steps: 1) dissolving 6-methyl-5-heptene-2-ketone and aluminium isopropoxide with molar rate at 1:0.35-1 into benzene or toluene solution; reducing under 60-120 deg.c; hydrolyzing into 6-methyl-5-heptene-2-alcohol; 2) halogenating 6-methyl-5-heptene-2-alcohol and halogenating agent with molar rate at 1:0.35-2 under -10-80 deg.c to produce 2-chlorine-6-methyl-5-heptene or 2-bromine-6-methyl-t-heptene; 3) reacting 2-chlorine-6-methyl-5-heptene or 2-bromine-6-methyl-t-heptene and magnesium to produce Grignard reagent; allocating the composition and formic ether with molar rate at 0.5-1:1 under -10-30 deg.c to do Grignard additional reaction; hydrolyzing; decompressing; distilling; obtaining the product. |
