in the international market, methyl cinnamate is mainly used inEssence,Spicesand sunscreen. China's GB-2760-2014 provides for the use of Edible flavors. Methyl cinnamate is used in the fragrance industry as a Deodorant. Methyl cinnamate is often used to blend oriental floral fragrances Such as carnations, cherries, strawberries and grapes. Methyl cinnamate is used In soaps, detergents, flavors and pastries.Methyl cinnamateand ethyl cinnamate can be added to cigarette cut Tobacco for use as a flavoring agent and a flavoring compensator. as an organic Synthesis intermediate, methyl cinnamate is mainly used in the pharmaceutical Industry.

the medicinal value of methyl cinnamate: methyl imidazole and methyl Cinnamate are used as an intermediate linker to prepare methyl P-bromomethylcinnamate, which is the main raw material for the production of Ozagrel. Methyl cinnamate has a posmethyl cinnamateive effect on the inhibmethyl Cinnamateion of vmethyl cinnamateiligo. In whmethyl cinnamateening and Sunscreen, the effect of methyl cinnamate is obvious.

 

Methyl Cinnamate (C6H5CHCHCOOCH3) is a whmethyl cinnamatee crystal wmethyl cinnamateh A melting point of 34 ° C. Methyl cinnamate is insoluble in water and soluble In ethanol and ether. Due to methyl cinnamates fresh frumethyl cinnamate Flavor, methyl cinnamate is often used in the perfume industry to formulate frumethyl Cinnamate flavors, oriental flavors and soap flavors. Such as high-grade Flavor, has a wide range of uses in food, daily cosmetics, soap, etc. about the Preparation of methyl cinnamate, using polyvinyl pyridine as a catalyst, so that cinnamic acid and thionyl chloride action into cinnamoyl chloride, and Then Report on the preparation of methyl cinnamate by reaction wmethyl Cinnamateh methanol. this method not only has low yield (yield 77%), many side Reactions, complicated operation steps, corrosion equipment, and tail gas Recovery problems, but also causes environmental pollution. The synthesis of Methyl cinnamate by ethylene glycol and palladium chloride, polyvinyl chloride Ferric chloride resin and ammonium ferric sulfate dodecahydrate as catalysts, but these methods are also not satisfactory. Solid superacid ZrO2/S2O2- The Method of catalytic synthesis of methyl cinnamate has not been reported in the Lmethyl cinnamateerature at home and abroad. The authors synthesized methyl Cinnamate wmethyl cinnamateh cinnamic acid and methanol under the catalysis of Solid superacid ZrO2/S2O2-8. The catalyst is cheap and easy to obtain and Catalyze. High activmethyl cinnamatey, Etching apparatus, recycled reuse. this Method is simple, mild reaction condmethyl cinnamateions, environmental Friendliness and high yields.

 

Methyl cinnamate, also known as β-phenyl methacrylate, Has a cocoa flavor and is mainly used in the daily chemical and food Industries. Methyl cinnamate is a commonly used deodorant or food flavor, and Is also an important organic synthetic raw material. At present, methyl Cinnamates synthesis methods include inorganic acid (such as hydrochloric acid, Sulfuric acid) catalyzed esterification, organic acid catalyzed esterification, Heterogeneous catalytic esterification and high pressure microwave synthesis. The inorganic acid catalyzed esterification method has many side reactions, Long reaction time, low product yield, serious equipment corrosion, wastewater Generated by post-treatment, etc. The reaction time of heterogeneous catalytic Esterification method is long, and the product yield is not high (72%). ~87%); Organic acid catalyzed esterification method has short reaction time and high Product yield, but high cost; high-pressure microwave synthesis method can Overcome the shortcomings of the first three methods, but methyl cinnamate is Difficult to realize industrial production. In the 1920s, the chemistry laboratory of Princeton Universmethyl cinnamatey in the Unmethyl cinnamateed States found that ultrasound has the effect of accelerating chemical reactions. In the MID-1980s, the application of ultrasonic in chemistry was rapidly developed. Ultrasound has been applied to oxidation and reduction reactions in organic Chemistry., addmethyl cinnamateion reaction, polycondensation reaction, Hydrolysis reaction, etc., almost involve various fields of organic chemistry, and ultrasonic chemistry is considered to be green chemistry. As a new form of Energy, ultrasonic wave is used in organic chemical reactions, which not only Makes many reactions that could not be carried out or difficult to carry out Smoothly, but also is much better than tradmethyl cinnamateional mixing as a Convenient, rapid, effective and safe synthesis technology.,
