Preparation method of muskmelon aldehyde, muskmelon aldehyde and application thereof

The invention relates to a preparation method of muskmelon aldehyde, muskmelon aldehyde and an application thereof, the preparation method comprises the following steps: carrying out a Darzen condensation reaction on 6-methyl-5-heptene-2-ketone, chloroacetate and an acid-binding agent under the condition of adding a solvent and a phase transfer catalyst to obtain epoxy caprylate; and saponifying the obtained epoxy caprylate in an aqueous solution of alkali to generate corresponding salt, acidifying with acid to obtain 3, 7-dimethyl-6-ene-2, 3-epoxy caprylic acid, carrying out a reduced pressure decarboxylation reaction on 3, 7-dimethyl-6-ene-2, 3-epoxy caprylic acid, and adding a mixture composed of an antioxidant and a polymerization inhibitor to obtain the muskmelon aldehyde product. Theconditions of the preparation method are easier to control, the production is safer, the yield is higher, and the product purity is high.
