Synthetic fragrance compounds microwave technology
    1 aldehyde synthesis spices
    Jasminaldehyde is a strong flavor with artificial flavors , which through chemical reaction , but this reaction process, there are serious side effects, such as heptaldehyde self condensation of benzaldehyde Cannizaro reaction . Chai Lanqin such as the use of microwave technology jasmine aldehyde synthesis , only simplifies processing steps to improve the yield of Jasminaldehyde , and reaction selectivity of the reaction time from 72 h reduced to 1 min, and the yield of 82%.
    (2) the synthesis of ethers spices
    R a CAI ether is a synthetic perfumes with orange blossom aroma , flavor commonly used in soap and detergents flavors , the traditional method of generating by households naphthol and methanol in the presence of sulfuric role in the system , but this method reflux long reaction time is not conducive to industrial production. Zhang Min households such as the use of microwave radiation naphthol catalytic reaction of methanol and dimethyl ether synthesis reaction rate is Tsai households increased nearly 100 times, and the yield is improved , processing is easier after the experiment has potential prospects for industrial applications .
    3 acids synthesis spices
Bai Lin et al studied the presence of a phase transfer catalyst under microwave radiation technology applied to the synthesis of benzoic acid . They studied the microwave power , irradiation time and catalyst for the oxidation reaction, and to find the optimum synthesis conditions , production rate of 85%
4 Synthesis of Heterocyclic spices
    Microwave technology is often used for the synthesis of nitrogen-containing heterocyclic compounds , such as : Fischer reaction of the synthesis of an effective noise cited method, but heating the reaction under normal conditions , Ail yield very low noise , and microwave radiation, montmorillonite (KSP) as a carrier , just 5 min ie 72% -90 % yield generated is called noise .
