    Preparation Method
    Isopropyl triphenyl phosphoric acid preparation method, the first phenol and trichloroester phosphate as raw materials, with isopropyl alcohol as modifier. Phosphorus oxychloride is added to phenol, temperature control and slow stirring, followed by dropwise addition of isopropyl alcohol. Under the action of hydroxyl groups, esterification reaction occurs. Among them, weak bases or metal salts are often used as catalysts to promote smooth reaction and reduce side production. The temperature in the crucible gradually rises, and the by-product hydrogen chloride escapes. After the reaction is completed, it is washed with water to remove impurities, and vacuum distilled to obtain the finished product. The catalytic mechanism lies in activating the hydroxyl group to make it attack phosphorus oxychloride, which is bonded into phosphorus esters. After isopropyl is added, triphenyl phosphate is finally obtained. The product is clear, heat-resistant and flame-retardant, widely used in plastics and rubber, Seiko manufacturing, rigorous construction method, and is especially

    Toxicity Research
    Isopropylated Trisphenyl Phosphate, a chemical essence, is widely used in plastics, paints and flame retardant materials. Its physical properties are stable, but the toxicity cannot be ignored. In the past, some scholars took mice as a test and forced them to ingest. It was found that the liver and kidney tissue were damaged, the weight was slowed down, the enzymes in the blood were abnormal, and the nervous system was slightly disturbed. There are also long-term exposures, suffering from respiratory tract irritation and throat discomfort. Repeated cell tests revealed that it can cause apoptosis and partially promote oxidative stress. However, the toxicity varies from dose to dose, and low doses or no significant harm, but high doses can cause acute and chronic changes. Its metabolites accumulate in the body for a long time or are potentially dangerous, and the cover should be carefully checked. For work, it is especially necessary to protect and reduce exposure to ensure safety.
