Keywords: Hydrogenated cinnamic acid (3-phenylpropionic acid), flavors, spices, synthetic flavors, intermediate drug, rasagiline Description: Hydrogenated cinnamic acid (3-phenylpropionic acid) is a white prismatic crystal having a melting point of 48.5 °C, a boiling point of 280°C, 125-129°C (0.8 kPa), and a relative density of 1.071. Soluble in hot water, alcohol, benzene, chloroform, ether, glacial acetic acid, petroleum ether and carbon disulfide, slightly soluble in cold water. It can volatilize with water vapor. Parkinson's disease, also known as "tremor palsy", is a central nervous system degenerative disease, most commonly found in middle-aged and elderly people, and is listed by the World Health Organization as one of the "world's difficult diseases." With the aging of the society, there are more than 1.8 million Parkinson's patients in China, and the incidence is increasing at a rate of 0.1% per year. Because there is no suitable medical treatment, about 20-25% of patients eventually lose their lives. ability. In order to solve this problem, in 2005, Denmark LUNDBECK company and Israel TEVA company developed a rasagiline through long-term joint experiments. Compared with the first generation of therapeutic drugs, according to the Canadian Medical Post report, rasagiline treatment can relieve the symptoms of Parkinson's disease for up to 6 years, and also has a certain protective effect on the nerves. However, due to the high price of raw materials and the complicated preparation methods, the price of rasagiline has remained high and the patients are suffering. The latest research found that rasagiline is prepared by using low-cost hydrogen cinnamic acid as an intermediate. It has the advantages of simple operation, low cost and high yield. The price of regagiran is cheaper than other drugs. More than 50% brings new hope to patients. In addition, the recent International Institute of Chemistry has shown that hydrogenated cinnamic acid can also be used as an intermediate in the treatment of the diabetes drug glibenclamide. Diabetes is a worldwide stubborn disease, and its alias for foreign countries is called "silent killer." There are currently more than 92 million diabetic patients in China, and another 100 million are potential patients. Glibenclamide is the most effective drug for oral hypoglycemic, but it has been expensive due to the price of raw materials and has strong toxic side effects. In the modern pharmaceutical industry, the cinnamon series-hydrocinnamic acid is used as an intermediate, which has certain auxiliary effects on reducing side effects and lowering blood sugar.

Simultaneous determination of the anticonvulsants, cinromide (3-bromo-n- ethylcinnamamide), 3-bromocinnamamide, and carbamazepine in plasma by high- performance liquid chromatography. 3-Bromocinnamic acid is used as an organic synthesis of raw materials, fine chemicals, pharmaceutical intermediates. Abstract A high-performance liquid chromatographic method is described for monitoring plasma concentrations of cinromide (3-bromo-N-ethylcinnamamide) and its de- ethylated metabolite. Carbamazepine levels can be easily measured by the same technique. The N-isopropyl analogue of cinromide is used as internal standard, and all compounds are easily separated on a reversed-phase column operated at 55 degrees with a small-diameter pre-column maintained at the same temperature. The extraction is rapid and generally applicable to plasma and urine samples that are to be analyzed by reversed-phase chromatography. Short- and long-term reproducibility studies show less than 4% relative standard deviation for replicate determinations for all drugs. Limits of quantitation are 10-20 ng/ml with an internal standard concentration of 3 micrograms/ml. Another metabolite of cinromide, 3-bromocinnamic acid, which may have some anticonvulsant effect, can be analyzed simultaneously by buffering the mobile phase and adding an ion-pairing reagent. Storage: Pay attention to the source of fire, especially to avoid sunlight, and store in a cool place.

Cinnamyl chloride can also be used to synthesize the anti-inflammatory and analgesic drug Sinnoxicam (cinnoxicam) and other fine chemicals. A reagent for the determination of trace water. Production preparation: Cinnamyl chloride is obtained by the reaction of sodium cinnamate with acetyl chloride. The acetyl chloride and benzene are mixed into solution, and the dried sodium cinnamate is added several times under stirring from time to time. After each addition, the carbon dioxide is released and the next time is added. Then reflux for 2 hours. After a little cooling, the resulting sodium chloride and trace unreacted sodium cinnamate are filtered out. The filtrate was distilled to remove benzene at atmospheric pressure and then distilled at 131C (1.47kPa) to obtain the product in 75-90 yield. Carbon tetrachloride can be recrystallized when purification is needed. Cinnamyl chloride was prepared by the reaction of cinnamic acid with dichloro sulfoxide. Polyvinyl cinnamate adhesive (PVAC,) is a linear polymer compound with molecular weight of 15000 ~ 20 000, which is obtained by esterification of polyvinyl alcohol and cinnamyl chloride. The photosensitive adhesive was prepared by adding 5- nitroacenaphthene and organic solvent cyclohexanone, that is, the double bond of the molecule was opened and solidified under ultraviolet light irradiation. It has important applications in the manufacture of integrated circuits and micro components. A photoresist, polyvinyl cinnamate, synthesized from polyvinyl alcohol and cinnamyl chloride in a pyridine solvent. The prepared photoresist is called KPR.. The photochemical dimerization of the double bond of cinnamate was formed under the action of ultraviolet light, and it was turned into an insoluble substance. KPR was the first photoresist used in photolithography, and 5- nitroacenaphthene was usually added as Guang Min. Photoresist, also known as photoresist, can be used in photolithography, which is widely used in printing and electronic industry. Its working principle is that the light part is crosslinked to form the insoluble hardening film, which is processed into negative image (negative glue), or the original insoluble glue becomes soluble after illumination, and is processed as a positive image (positive glue).

Cosmetics Hydroxycinnamic acid can inhibit the activity of tyrosinase monophenolase and diphenylase, resulting in a 50% reduction in the activity of monophenylase and diphenylase, and inhibiting the production of melanin in cosmetics. 4. Chemical industry 1) it is a very important flavor for hydroxyl cinnamic acid. The permitted use of spices is mainly used to prepare spices such as fragrant cherries, apricots and honey.In the daily chemical industry used to prepare soap and cosmetics fragrance. 2) p-hydroxycinnamic acid is also a strong conductive material, which has been widely studied in the LCD industry in recent years.The photosensitive p- hydroxypolyimide was synthesized by the graft reaction of hydroxypolyimide and p- hydroxycinnamic acid.The synthesis of p-hydroxypolyimide as liquid-crystal oriented layer is used in the liquid crystal display device, which proves that it has good thermal stability. Liquid crystal display applications Nowadays, liquid crystal display (LCD) has replaced the CRT traditional display as the main display device.However, although the liquid crystal display technology is increasingly mature, it is still not perfect. The main reasons are that the liquid crystal orientation layer material, as the key material of liquid display, is generally of low thermal stability, poor electrical conductivity and weak photosensitivity.The liquid-oriented layer directly affects the performance and service life of the LCD. The thermal stability of the material of the liquid- oriented layer is not good, which can easily cause the black screen of the liquid display mobile phone and automatically shut down.Computer liquid display screen black screen, repeated automatic switch;LCD TV screen, automatic platform, and other failures to shorten the service life of devices.In order to optimize the performance of liquid display devices, the best solution is to develop a new material with both good orientation to the liquid crystal and good thermal stability at the liquid crystal phase transition temperature.Many foreign authoritative research institutions have made great efforts to explore this, but they have been searching for years without success. Based on orientation technology, there are many kinds of polymer materials used in liquid crystal orientation layer, among which polyimide (PI) is the most commonly used liquid crystal orientation layer functional material.This is because PI has such excellent characteristics as high temperature resistance, corrosion resistance, high hardness, easy film formation and low production cost, which can well meet the industry's requirements on the characteristics of oriented layer materials.Since the display is a kind of equipment with high current, high power and high heat, the thermal stability of the device is crucial, which is exactly the weakness of PI.
