What are the applications of dye intermediates?


o-Chlorobenzoic acid
Mildew inhibitor, it can prevent the clothes from getting moldy and rotting. The main raw material for making it is an intermediate - o-chlorobenzoic acid. o-Chlorobenzoic acid is an important intermediate in the pesticide, pharmaceutical and dye industries with a wide range of uses. Drugs such as the antipsychotic perphenazine, the adrenomimetic drugs Zenglubenxin and Chuantong, the antifungal drugs clotrimazole, chlorpromazine, ketamine, and diclofenac are standard reagents for alkaline and iodometric methods and are used as adhesives and paint preservatives. In addition, it also plays a major role in dyes. We can’t do without taking pictures every day. Everyone has their own photos. The body of the photo is the film, and the body of the film can be made from o-chlorobenzoic acid. In chemistry, isomers often have similar chemical properties, so p-chlorobenzoic acid also has similar functions to o-chlorobenzoic acid, and is also an intermediate for pesticides and pharmaceutical dyes. Because of them, life has more colorful beauty and memories that can last forever. Promote the progress of life and improve the quality of life.
In contemporary life, mobile phones, TVs, refrigerators, and cars have become an important part of our lives, and these products have brought a lot of convenience and excitement to our lives. Using the mobile phone, you can chat and communicate with friends and relatives in different places through a thin display screen. Using TV, you can watch the customs, beautiful scenery from all over the world, learn and have fun. The use of refrigerators prolongs the freshness of food, and the use of cars makes us walk faster. An important part of these products is biquinol. Biphenol is an important organic intermediate, used as rubber antioxidant and plastic antioxidant, and can also be used in colorless vulcanized rubber products, food packaging rubber products and medical latex products. The tires on the vehicles we take, the plastic bags we use for shopping, the ping-pong paddles for entertainment, the rubber seals on food packaging, and the medical gloves in hospitals, etc. can all be made from biquinol. In terms of synthetic polymers, due to their good heat resistance, they can be used as modified monomers for polyester, polyurethane, polycarbonate, polysulfone and epoxy resin to produce excellent engineering plastics and composite materials. Wait. In automobiles, engineering plastics are mainly used for bumpers, fuel tanks, instrument panels, body panels, doors, lamp covers, fuel pipes, radiators and engine-related parts; in machinery, engineering plastics can be used for bearings, gears, Mechanical parts such as screw nuts, seals and mechanical structural parts such as shells, covers, handwheels, handles, fasteners and pipe joints; in electronic appliances, engineering plastics can be used for wire and cable covering, printed circuit boards , insulating film and other insulating materials and structural parts of electrical equipment; in household appliances, engineering plastics can be used in refrigerators, washing machines, air conditioners, TV sets, electric fans, vacuum cleaners, electric irons, microwave ovens, rice cookers, radios, combined stereos In equipment and lighting; in chemical industry, engineering plastics can be used in chemical equipment such as heat exchangers, chemical equipment linings, and in chemical pipelines such as pipes and pipe fittings, valves, and pumps. In addition to these, its high-purity products are mainly used in the synthesis of liquid crystal polymers. It is mainly used to make LCD screens of mobile phones, TVs and other electronic products.
