First, phthalic anhydride plays an important role in the field of drug manufacturing. It is a key raw material for the manufacture of anti-inflammatory drugs, gastrointestinal drugs, antibiotics, anticancer drugs and other drugs. Ib qho ntxiv, phthalic anhydride tseem yog ib qho tseem ceeb rau kev npaj ntawm ntau yam tseem ceeb rau kev txhawb kev cog thiab nce qoob loo loo.

Secondly, phthalic anhydride is also widely used in the dye and fragrance industry. Ua ib nrab nyob rau qhov tuag thiab txuj lom, phthalic anhydride yog siv los ua txuj lom, thiab lwm yam khoom noj khoom haus thiab cov ntxhiab tsw rau tib neeg lub neej.

In addition, phthalic anhydride also plays an important role in the manufacture of plastics and rubber. It is an important raw material for the manufacture of polymer compounds such as polyphenylene ether, polyamide, and polyimide. Cov duab no muaj zog no muaj cov khoom siv lub cev thiab tshuaj ruaj khov, thiab siv tau dav hauv cov chaw tsim khoom, muab kev txhawb nqa muaj zog rau kev txhim kho hauv zej zog.

In the field of organic synthesis, phthalic anhydride has a wide range of applications. Nws tuaj yeem siv rau carbonlylation, propylene oxidation, npaj ntawm acters acters, aldehyde thiab ketrical actification, nitric acid thiab alkaline oxidation. Hauv inorganic synthesis, phthalic anhydride tuaj yeem siv los ua cov synthesize cov ntsev, thiab tseem tuaj yeem siv los ua cov khoom siv Polymerization rau cov xov tooj liab qab. These synthetic reactions provide a rich material basis for the development of the chemical industry.

In addition, phthalic anhydride also has important applications in the field of fine chemicals. Nws tuaj yeem siv rau ntau yam sib cais crystallization thiab catalytic cov tshuaj tivthaiv, thiab tseem siv tau rau kev npaj thiab ua rau muaj kev sib cais ntawm ntau cov inorganic calcium sulphur polymers. In mining processing, phthalic anhydride can be used for mineral processing of ore deposits to improve the mining efficiency and quality of ore. Ib qho ntxiv, phthalic anhydride kuj tseem siv tau los ua cov khoom siv raw rau cov tshuaj tua kab thiab tshuaj tua kab, ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov qoob loo thiab cog qoob loo.

In industrial production, phthalic anhydride is mainly used as a solvent and extractant. Vim nws lub boil qis thiab siab solubility, phthlic anhydride yog dav siv nyob rau hauv Petroleum Refining thiab Petrochemical Industries raws li cov khoom tawg. Nyob rau tib lub sijhawm, nws kuj tseem tuaj yeem siv los ua cov tshuaj lom chromatographic reagent thiab lwm yam rau cov txuj lom, muab txhais tau tias yog siv tshuaj ntsuam xyuas tshuaj lom neeg thiab txuj lom extraction.

Ib qho ntxiv, phthalic anhydride tseem tuaj yeem siv los npaj cov vanillin, npaj cov tshuaj tiv thaiv kab ntxwv, thiab cov tshuaj tiv thaiv zoo rau kev kho cov khoom siv hlau nto. Nyob rau hauv cov roj hmab thiab yas tsim, pharicic anhydride tuaj yeem siv los ua cov roj hmab ntxiv thiab cov yas ntxiv los txhim kho cov khoom lag luam thiab cov khoom lag luam zoo.
