What is Methyl Cinnamate?

Methyl cinnamate is an ester natural substance, which is a derivative of methyl ester, as well as is a white or clear solid with a strong fragrant scent. It happens naturally in a selection of plants, including fruits, such as strawberries, as well as some cooking seasonings, such as Sichuan peppercorns and some ranges of basil. Eucalyptus has the highest possible recognized focus of methyl cinnamate (98%), with 2– 6% fresh weight in fallen leaves and twigs.

Methyl Cinnamate Uses

  1. Methyl cinnamate can be used as a fixative for blending carnations and oriental flavors. Used as a fixative and a daily chemical essence: it can be used to prepare roses, narcissus, and smoke in daily chemical products such as soaps and detergents. Garlic, carnation, lilac and other daily chemical flavors; used as food flavors: in flavoring agents and cakes, used to prepare strawberry, grape, cherry, peach, cream, vanilla and other food flavors.
  2. Methyl cinnamate is a flavoring that is temporarily permitted in GB 2760-1996. It has a good fragrance-fixing effect. It is mainly used in the preparation of cherry, strawberry and grape flavors.
  3. Methyl cinnamate is used as a fixative in the perfume industry, often used in the deployment of carnations and oriental floral essences, in soaps, detergents, flavors and pastries. As an organic synthesis intermediate, it is mainly used in the pharmaceutical industry.
  4. Methyl cinnamate is mainly used in the preparation of flavors such as cherry, strawberry and grape.

Application of Methyl Cinnamate

1. Catalyzed transesterification reaction to prepare n-butyl cinnamate
CN201210026469.3 provides a method for preparing n-butyl cinnamate by catalyzing transesterification reaction, which is a method for transesterification of methyl cinnamate and n-butanol catalyzed by microwave synergistic 1-butyl-3-methylimidazolium bisulfate ionic liquid The method for preparing n-butyl cinnamate by reaction. The object of the present invention is achieved through the following technical solutions:

A method for preparing n-butyl cinnamate by catalyzed transesterification, comprising the following steps: adding methyl cinnamate, catalyst 1-butyl-3-methylimidazolium bisulfate and n-butanol in a microwave reaction tank, fully Mix well to obtain the reaction raw materials; the molar ratio of methyl cinnamate and n-butanol is 1:6 to 1:16; the reaction raw materials are irradiated with microwaves for 5 to 60 minutes, the microwave power is set to 100 to 500W, and the microwave irradiation temperature Set at 70-117°C, and obtain n-butyl cinnamate after microwave irradiation.

The present invention adopts the novel process of synthesizing n-butyl cinnamate through the transesterification reaction of methyl cinnamate and n-butanol catalyzed by microwave synergy with 1-butyl-3-methylimidazolium bisulfate ionic liquid, which has high heating efficiency and short reaction time Short, low energy consumption, simple process, easy after-treatment, recyclable catalyst and environmental friendliness, it is a new energy-saving green chemical method in line with sustainable development and environmental friendliness, especially in our country today Under the situation of severe energy shortage, it has better prospects for industrialization.

2. For the preparation of agricultural compositions
Methyl cinnamate is a common root exudate, which was often treated as an allelochemical or other functional substance before, and the research on its ecological function in soil is very lacking. CN201810427224.9 has proved that methyl cinnamate has a good nitrification inhibitory effect through pure bacterial culture and soil addition tests, can be used as a biological nitrification inhibitor, and has a good nitrification inhibitory effect.

CN201810427224.9 gives an agricultural make-up. The raw product components of the agricultural composition are 40g of urea, 2g of methyl cinnamate, 10g of hygroscopic fragments, and also 10g of binder; the active ingredients are blended with each other, compressed, Dry as well as granulate. Compared to previous art, the helpful effect of the present development is:

( 1) The expense is reduced. In the development, methyl cinnamate is used as a nitrification inhibitor for controling soil N conversion, and also is utilized in an agricultural structure for maintaining plant foods; the farming structure prepared by the method has less manufacturing investment, steady product quality, as well as is easy to take care of.

( 2) Compared with the existing nitrification prevention DMPP etc., the present development has the advantages of easy synthesis approach, large source of raw materials and reduced cost.

( 3) The application impact is excellent. The nitrification inhibitor given by the invention can be used to maintain plant foods, and after being related to soil, N improvement can be properly controlled.

Preparation of Methyl Cinnamate

At present, its synthesis methods include inorganic acid (such as hydrochloric acid, sulfuric acid) catalyzed esterification method, organic acid catalyzed esterification method, heterogeneous catalyzed esterification method and high-pressure microwave synthesis method. HECK reaction, as the coupling reaction of aromatic haloalkanes and alkenes containing α-electron-withdrawing groups, is one of the important reactions for forming C-C bonds in organic synthesis, and has been widely used.

However, similar to Suzuki et al., HECK reactions usually require the catalysis of transition metal palladium and the assistance of organophosphine ligands. Because the palladium catalyst is expensive and toxic, and the organic phosphine compound is highly toxic and cannot be reused, the HECK reaction has not been widely used in industry. CN201510558928.6 provides a synthetic method for preparing methyl cinnamate catalyzed by a nano palladium catalyst prepared by using ionic liquid. In order to achieve the above object, the invention provides a kind of synthetic method of methyl cinnamate, and its preparation process is as follows:

1) Add 15-25 parts by weight of ionic liquid into the reaction flask, and stir magnetically for 10-15 minutes at 25°C;

2) Slowly add 25-40 parts by weight of surfactant, and continuously feed nitrogen into the system during the process, and dissolve the two under stirring conditions;

3) Slowly add distilled water to the reaction bottle at a rate of 1-3ml/min until the whole reaction system is transparent and clear, start heating to 40-70°C, add 6-10 parts of palladium chloride solution after the temperature is constant, and continue stir;

4) When the system turns from light yellow to dark black, and there is no precipitation in the reaction bottle and the system is uniform, slowly raise the temperature to 70-85°C, and add 30-40 parts of iodobenzene, 50-75 parts of methyl acrylate and 40-70 parts of triethylamine, stirring for 3-5h;

5) After the reaction, the product was separated, and the product was confirmed to be methyl cinnamate by nuclear magnetic resonance analysis, and the calculated yield reached more than 99%.
