Synthesis And Application Of Milk Lactone

Further improve the process route for the synthesis of cyclohexanone and butyraldehydemilk lactone, factors that affect the yield in each step of the analysis, and conclude that theoptimal conditions:①The2-D cross cyclohexyl ketone synthesis: polyethylene glycol400as aphase transfer catalyst(4%of the amount of butyraldehyde), the alkali concentration of1%,n(n-butyl aldehyde):n(cyclohexanone)=1:1.8, the temperature is30°C, reaction time is1.5h, theoxalic acid as a dehydrating agent (7%of the amount of butyraldehyde);②The2-butylcyclohexanone synthesis: hydrogen pressure is2.5MPa, temperature is40°C;③Theε-decalactone synthesis: peroxide urea as the oxidant, n(2-butyl-cyclohexanone):n(ureaperoxide)=1:4, the temperature is30°C, reaction time is1h;④The5(6)-the synthesis of thedecanoic acid: alkali concentration of30%, saponification reaction temperature is110°C,reaction time is3h. The reaction yield is30.8%. Compared with other synthesis methods, theprocess route using a phase transfer catalyst and urea peroxide the oxidizer, with the advantagesof easy operation, low cost and high yield.The application of milk lactone in biscuits and cakes have been discussed, biscuits andcakes with milk lactone have been made, the best dosage of milk lactone in biscuits and cakesand other baked goods is0.6‰to0.8‰. Compared with the milk flavor, when milk lactoneadded in biscuits and cakes, the milk flavor is more durable and attractive.
