What is Trans-Cinnamic Acid?

Trans-Cinnamic Acid is also called cinnamic acid as well as cinnamic acid. Molecular formula: C6H5CHCHCOOH, English Trans2Cinnamicacid, the appearance is white monoclinic crystal, with a minor cinnamon scent. Trans-Cinnamic Acid is a vital great chemical synthesis intermediate, which is widely utilized in chemical items such as medication, fragrance, plastic and also photosensitive resin.

2. British Unilever has actually acquired the PCTInt license of the Globe Copyright Company. Appl. Wo0187, 080 (2001, 11.22) This short article introduces the composition of cinnamic acid and pasteurization assistance, which have solid antiseptic as well as also disinfectant results.
3. Trans-Cinnamic Acid is likewise an aspect of capsaicin synthase – cinnamic acid hydrolase, which can be utilized to expand high-yielding capsaicin-rich pepper options, which will substantially boost the premium quality of peppers, consequently effectively advertising the development of pepper automation.
4. The mildew-proof, anti-corrosion in addition to sterilization making use of Trans-Cinnamic Acid can be put on the conservation along with anti-corrosion of grains, vegetables along with fruits.
5. It can furthermore be utilized in merlot to make its color intense.
6.Trans-Cinnamic Acid has a solid stimulating outcome and additionally can be directly added to all foods.

In the pharmaceutical market, it can be taken advantage of to manufacture important medications for the treatment of coronary heart issue. medicine, and more. It can likewise manufacture chlorophenylbutyric acid along with cinnamon benzene piperazine, which are used as spine cone depressants and additionally antispasmodics. Usually utilized for logical apoplexy, logical arteriosclerosis, coronary arteriosclerosis in addition to various other problems. It has a significant repressive effect on the development of lung adenocarcinoma cells. Cinnamic acid is an effective prevention of A-5491 human lung adenocarcinoma cells in addition to has outstanding application worth in anticancer.

Trans-Cinnamic Acid can be made use of in charm. Tyrosinase is the crucial enzyme in melanin synthesis, which starts the waterfall action of transforming tyrosine right into melanin biopolymers. Trans-Cinnamic Acid has the capacity to prevent the formation of black tyrosinase. It has a specific seclusion result on ultraviolet rays, as well as can make brown locations lighter or perhaps disappear. It is among the essential components in ingenious sun blocks. The remarkable antioxidant household or commercial buildings of Trans-Cinnamic Acid are great for reducing the appearance of creases.

Preparation of Trans-Cinnamic Acid

Report One,
In a 1000mL four-necked flask, insert a stirrer, a thermometer, a dropping funnel and a rubber tube connected to an oxygen cylinder. Add 20 g of caustic soda, 600 mL of water, and 6 g of silver/copper catalyst, stir to heat up, feed oxygen, flow rate 4 L/min, and control temperature to 45-50 °C. After 10 minutes, 60 g of cinnamaldehyde was added dropwise, and the flow rate was 0.5 g/min. After the dropwise addition, oxygen was continued for 15 minutes. The filter residue was filtered off to obtain a pale yellow solution, and the filter residue was washed with water. The washing solution was combined with the filtrate, heated to 70-80°C, added with hydrochloric acid, adjusted to pH 2, cooled to room temperature, filtered with suction, and dried to obtain 64.5g of Trans-Cinnamic Acid white crystals with a melting point of 132-133°C and a yield of 64.5g. was 95.8%.

Report Two,

Trans-Cinnamic Acid exists in both cis and trans isomers. Trans isomers can be used as food flavorings, in addition to being extracted from natural raw materials (Styrax incense), they can also be prepared as follows; 1. From benzaldehyde, anhydrous sodium acetate and acetic anhydride in the presence of pyridine, from the Boqin reaction . 2. Benzaldehyde condensation reaction from benzaldehyde and ethyl acetate. 3. From the reaction of benzaldehyde and acetyl chloride. 4. Oxidation from benzylidene acetone with sodium hypochlorite. The preparation method (1) is as follows: 32.5 kilograms of anhydrous potassium carbonate and 25 kilograms of acetic acid are added to the reaction pot, slowly heated to 120° C., and when the carbon dioxide gas is reduced, 100 kilograms of benzaldehyde and 100 kilograms of acetic anhydride are added dropwise. Under stirring, heat to 150-160°C, and control the temperature at the top of the fractionation column to be about 120°C. When about 45 kg of acetic acid is evaporated, 75 kg of acetic anhydride is added dropwise. When no more acetic acid is evaporated, the reaction The temperature was increased to 180°C. Excessive acetic anhydride was evaporated, and it was finished in about 3h. Add 10% sodium hydroxide to neutralize to pH=9. A small amount of benzaldehyde was removed by passing steam and left overnight. Acidify with 10% hydrochloric acid, white precipitate will appear at this time, reach pH=5, filter and wash with a centrifuge, and then place the cinnamic acid in a drying room at 100-110 °C for blast drying to obtain the finished product of Trans-Cinnamic Acid.
