Blending apples and cherries can be used as apple flavors, cherry flavors, fruit flavors and floral flavors. 2. It can be used as an aromatic mixture in soap, shampoo, washing powder and daily cosmetics. 3. Cinnamic acid itself is a kind of perfume, which has a good fragrance preservation function. It is usually used as a raw material for fragrance matching, which can make the fragrance of the main perfume more fragrant and volatile. Various esters of cinnamic acid (such as A, B, C, D, etc.) can be used as fixative for beverages, cold drinks, candy, alcohol and other foods. The role of cinnamic acid in medicine: 1. It is used to create "reassuring"; 2. Used to synthesize important drugs for treating coronary heart disease, such as clonidine lactate and xintongping; 3. Cinnamic acid can be used to synthesize chlorphenamine butyric acid and cinnamyl piperazine. The former is used as spinal relaxant and sedative, and the latter is used for cerebral thrombosis, cerebral arteriosclerosis, coronary arteriosclerosis and other diseases. Local anesthetic, bactericide, hemostatic, etc. The application of cinnamic acid in food additives: 1. Cinnamic acid is synthesized by microbial enzymatic method, and L- phenylalanine is the main raw material of sweet Aspartame, an important food additive. 2. As a flavoring raw material, it is also used as a fixative in spices, which can be used in drinks, cold drinks, candy, alcohol and other foods. 3. Cinnamic acid is also a component of capsaicin synthase-cinnamic acid hydrolase, which can be used to cultivate excellent pepper varieties with high capsaicin content by transgenic technology, which will greatly improve the quality of pepper, thus effectively promoting the industrialization development of pepper. 4. The use of cinnamic acid for mildew prevention, antisepsis and sterilization can be applied to the preservation and antisepsis of grain, vegetables and fruits. 5. It can also be used in wine to make it bright. The role of cinnamic acid in daily chemicals: 1. Tyrosinase is the key enzyme in melanin synthesis, which initiated the cascade chain reaction from tyrosine to melanin biopolymer. Cinnamic acid can inhibit the formation of black tyrosinase, has a certain isolation effect on ultraviolet rays, and can make brown spots lighter or even disappear. It is one of the essential ingredients in advanced sunscreen cream. 2. Cinnamic acid has a good fragrance preservation function, which is usually used as a raw material for fragrance distribution and also used as a fragrance fixative in daily chemical essence. The role of cinnamic acid in industry: ① Cinnamic acid can be used as corrosion inhibitor for zinc crossing, heat stabilizer for PVC, crosslinking agent for polyurethane and flame retardant for hydantoin. ② Cinnamic acid is still the main synthetic raw material of negative photosensitive resin.

a new electroplating technology-cinnamic acid gives wings to electroplating industry. As an important surface engineering technology, it has a history of more than 16 years since the patent application for silver plating in 198. Since the 2th century, with the progress of science and technology and the increasing degree of industrialization, the surface treatment of automobiles, machinery and equipment, aviation, electronics, light industry and other industries is inseparable from electroplating. Today, electroplating has developed from general decorative protection to high corrosion resistance and functionality. It is widely used in the basic processing industry in the fields of electronics industry, national defense industry and cutting-edge technology, and plays an important role in China's national economic construction. However, while electroplating plays a great role, it also seriously endangers the health of the people and destroys the surrounding environment. In particular, zinc plating, which accounts for 45%-5% of the whole electroplating industry, is accompanied by serious environmental problems, no matter whether it is cyanide-containing zinc plating or cyanide-free zinc plating (mainly sodium chloride), so that in 28, the country has to implement a new "new standard for electroplating pollution discharge". The new standard gives electroplating enterprises two years to buffer time to replace equipment and update raw materials. However, this is still the same for the electroplating industry: upgrading requires a large investment, which will inevitably lead to a large price increase, which is undoubtedly equivalent to dying in the fierce competition, and the only consequence of not upgrading is waiting for death. Therefore, whether we can find a kind of low-cost raw materials to make the electroplating industry embark on the road of green development has become a life-saving straw to get rid of the dilemma of electroplating "two deaths" and thus survive. China is a big electroplating country, and various advanced technologies have been embodied in China. Cinnamic acid can be used as brightener, etchant and additive in electroplating. Commonly used in chloride zinc plating, tin plating and other electroplating protective layer industries. Cinnamic acid can be used not only as the brightener and carrier brightener for acid zinc plating such as sulfate zinc plating brightener and potassium chloride zinc plating brightener, but also as the auxiliary brightener for other brightener products. Cinnamic acid can refine the crystallization of the coating, promote the main brightener insoluble in water to be evenly dispersed in the plating solution, further expand the bright current density range of the plating solution, improve the cathodic polarization of the plating solution, strengthen the low-level bright effect and obtain a fully bright coating; It can improve the dispersion ability and covering ability of the plating solution relatively, and has the characteristics of fast zinc feeding speed, fast light emitting speed and low consumption. Because the general main brighteners such as benzylidene acetone, cumaldehyde, benzophenone and O- chlorobenzaldehyde can only play a bright role in a certain current density range, the ideal coating can not be obtained by using them alone, and the synergistic effect can be achieved by using cinnamic acid together. As a brightener, cinnamic acid broadens the operating temperature. Generally, at 1~7℃, the dispersion ability and deep plating ability of the plating solution are still very good. The obtained coating is fine and bright, with low brittleness and low consumption, and has the function of impurity self-inhibition, and the plated parts also have strong corrosion resistance. Adding carnosic acid will not produce toxic or pungent gas, waste water, waste gas, noise, waste residue and other pollutants, and it does not contain radioactive, corrosive or toxic substances, which can save the later environmental protection treatment and greatly reduce the cost. At the same time, cinnamic acid has low price and convenient storage and transportation, which is indeed the gospel of electroplating. Hubei Yuancheng Pharmaceutical Co., Ltd. is the only large-scale enterprise that produces cinnamic acid in China. At present, I have long-term cooperation with the enterprise. I am Xiaogong 27-88322715, a salesman of Yuancheng. I believe that these latest information can bring new spring to the electroplating industry in China. In 212, I wish all enterprises new opportunities!
