1. Medicine
It can be used for the synthesis of rhododendron, a new expectorant drug, and as an intermediate in the production of clonidine, a coronary heart disease treatment drug in the pharmaceutical industry, as well as for the manufacture of local anesthetics, fungicides and hemostatic drugs; It has the effect of inhibiting cervical cancer; It can also be used to synthesize the anti-epinephrine drug Esmolol.
2. Agriculture
It is used in the production of plant growth promoters, long-acting fungicides and fruit and vegetable preservatives in the pesticide industry. In addition, p-hydroxycinnamic acid can also be used as a chemical reagent for the determination of uranium and hunger, and as the main raw material for the production of photosensitive resin, ethylene cork oil, is also used.
3. Cosmetics
P-Hydroxycinnamic acid can inhibit the activity of tyrosinase monophenolase and diphenolase, resulting in a 50% decrease in the activity of monophenolase and diphenolase, which is used in cosmetics to inhibit the formation of melanin.
4. Chemical industry
1) P-hydroxycinnamic acid is a very important essence spice. The allowed spices are mainly used to prepare spice cherries, apricots, honey and other spices. In the daily chemical industry, it is used to prepare soap and cosmetics essence.
2) P-hydroxycinnamic acid is also a powerful conductive material, which has been widely studied in the LCD industry in recent years. The photosensitive p-hydroxy polyimide was synthesized by the grafting reaction of hydroxy polyimide and p-hydroxycinnamic acid. The structure of photosensitive p-hydroxy polyimide was determined by IR and NMR. The synthesized p-hydroxy polyimide was used as liquid crystal orientation layer in liquid crystal display devices, which proved to have good thermal stability.
3) Application of LCD
Nowadays, LCD has completely replaced the bulky CRT traditional display and become the mainstream display device. However, although the liquid crystal display technology is becoming more and more mature, it is still not perfect. The main reason is that the liquid crystal orientation layer material, which is the key material of liquid display, is generally not high in thermal stability, strong in conductivity and photosensitivity. The liquid crystal orientation layer directly affects the performance and service life of the liquid crystal display. The thermal stability of the orientation layer material is not good, which is easy to cause the black screen and automatic shutdown of the liquid crystal display phone; The computer liquid display screen is black, and the automatic switch is repeated; LCD TV screen failure, automatic platform failure and other failures greatly shorten the service life of the device. In order to optimize the performance of liquid display devices, the best solution is to develop new materials with good orientation to liquid crystal and good thermal stability at liquid crystal phase transition temperature. In this regard, many foreign authoritative research institutions have made efforts to explore, but they have struggled for many years without results.
Based on orientation technology, there are many kinds of polymer materials used for liquid crystal orientation layer, among which polyimide (PI) is the most commonly used and widely used functional material for liquid crystal orientation layer. This is because PI has excellent characteristics such as high temperature resistance, corrosion resistance, high hardness, easy film formation and low production cost, which can well meet the requirements of the industry for the properties of oriented layer materials. Because the display is a kind of equipment with high current, high power and high calorific value, the thermal stability of the device is very important, which is exactly the weakness of PI.
