Usage:
In the international market, it is mainly used in essence, spices and
sunscreen. China's GB-2760-2014 provides for the use of edible flavors. It is
used in the fragrance industry as a deodorant. It is often used to blend
oriental floral fragrances such as carnations, cherries, strawberries and
grapes. It is used in soaps, detergents, flavors and pastries. Methyl cinnamate
and ethyl cinnamate can be added to cigarette cut tobacco for use as a
flavoring agent and a flavoring compensator. As an organic synthesis
intermediate, it 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 positive effect on the inhibition of vitiligo. In whitening and
sunscreen, the effect of methyl cinnamate is obvious.

Methyl cinnamate (C6H5CHCHCOOCH3) is a white crystal with a melting point of 34
° C. It is insoluble in water and soluble in ethanol and ether. Due to its
fresh fruit flavor, it is often used in the perfume industry to formulate fruit
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 with 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 literature at home and abroad.
The authors synthesized methyl cinnamate with cinnamic acid and methanol under
the catalysis of solid superacid ZrO2/S2O2-8. The catalyst is cheap and easy to
obtain and catalyze. High activity, Etching apparatus, recycled reuse. This
method is simple, mild reaction conditions, 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. It is a commonly used
deodorant or food flavor, and is also an important organic synthetic raw
material. At present, its 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 it is difficult to realize industrial production. In the 1920s,
the chemistry laboratory of Princeton University in the United 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. , addition 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 traditional mixing as a convenient,
rapid, effective and safe synthesis technology. , external heating method.
