Phthal anhydride 99%, npaj rau kev xa khoom ~

Daim Ntawv Thov:

Ua ntej, phthalic anhydride ua lub luag haujlwm tseem ceeb hauv kev tsim tshuaj yeeb. Nws yog cov khoom tseem ceeb rau kev tsim cov tshuaj tiv thaiv kev tiv thaiv, cov tshuaj tua hluav taws xob, tshuaj tua kab mob, tshuaj tiv thaiv tshuaj thiab lwm yam tshuaj. 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.

Thib ob, phthal anhydride tseem dav siv nyob rau hauv qhov xim thiab kev lag luam tshuaj tsw qab. 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.

Ib qho ntxiv, phthalic anhydride tseem ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom tawg thiab roj hmab. Nws yog ib qho khoom siv tseem ceeb rau kev tsim cov polymer sib xyaw xws li polyphenylene ether, polyamide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab polyimide, thiab 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.

Hauv thaj teb ntawm cov organic synthesis, phthal anhydride muaj ntau cov kev siv. 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. Cov kev tawm tsam no muab cov khoom siv nplua nuj rau kev txhim kho ntawm kev lag luam tshuaj lom neeg.

Ib qho ntxiv, phthalic anhydride tseem muaj cov ntawv thov tseem ceeb hauv kev ua haujlwm ntawm cov tshuaj zoo. 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. Hauv kev sib sau ua ke, phthalic anhydride tuaj yeem siv rau kev ua yeeb yam ntawm cov ee tso nyiaj kom txhim kho kev ua kom tau mining ua haujlwm thiab ua tau zoo ntawm 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.

Hauv kev lag luam ntau lawm, phthalic anhydride yog tsuas yog siv los ua cov kuab tshuaj thiab 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.
