Phthalic Anhydride, Npaj Txhij Rau Kev Xa Khoom ~

Daim Ntawv Thov:

Ua ntej, phthalic anhydride ua lub luag haujlwm tseem ceeb hauv kev tsim tshuaj. Nws yog cov khoom siv tseem ceeb rau kev tsim cov tshuaj tiv thaiv kev o, cov tshuaj kho mob plab, tshuaj tua kab mob, tshuaj tiv thaiv mob qog noj ntshav thiab lwm yam tshuaj. Tsis tas li ntawd, phthalic anhydride kuj yog cov tshuaj ua ntej rau kev npaj ntau yam tshuaj hormones cog xws li cov tshuaj hormones loj hlob thiab auxin, uas yog qhov tseem ceeb heev rau kev txhawb nqa kev loj hlob ntawm cov nroj tsuag thiab ua kom cov qoob loo ntau ntxiv.

Qhov thib ob, phthalic anhydride kuj siv dav hauv kev lag luam zas xim thiab tshuaj tsw qab. Ua ib qho nruab nrab rau cov xim thiab cov txuj lom, phthalic anhydride yog siv los ua cov txuj lom, cov xim, cov xim fiber ntau, thiab lwm yam. Nws cov khoom siv tshuaj lom neeg tshwj xeeb ua rau nws tsis tuaj yeem hloov pauv tau hauv cov teb no, ntxiv cov xim nplua nuj thiab cov tshuaj tsw qab rau tib neeg lub neej.

Ntxiv mus, phthalic anhydride kuj ua lub luag haujlwm tseem ceeb hauv kev tsim cov yas thiab roj hmab. Nws yog ib qho khoom siv tseem ceeb rau kev tsim cov tshuaj polymer xws li polyphenylene ether, polyamide, thiab polyimide. Cov tshuaj polymer no muaj cov khoom zoo heev thiab kev ruaj khov tshuaj lom neeg, thiab siv dav hauv tsheb, khoom siv hluav taws xob, kev tsim kho thiab lwm yam teb, muab kev txhawb nqa zoo rau kev txhim kho ntawm lub neej niaj hnub.

Hauv kev ua cov organic synthesis, phthalic anhydride muaj ntau yam kev siv. Nws tuaj yeem siv rau carbonylation, propylene oxidation, npaj cov esters carbon activated, hydrogenation qhuav, aldehyde thiab ketone esterification, nitric acid thiab alkaline oxidation. Hauv kev ua inorganic synthesis, phthalic anhydride tuaj yeem siv los ua cov ntsev ammonium, thiab kuj tuaj yeem siv ua tus neeg sawv cev polymerization tseem ceeb rau kev ua cov tooj liab zinc sulfide. Cov tshuaj tiv thaiv synthesis no muab cov khoom siv nplua nuj rau kev txhim kho kev lag luam tshuaj lom neeg.

Tsis tas li ntawd xwb, phthalic anhydride kuj muaj cov ntawv thov tseem ceeb hauv kev siv tshuaj zoo. Nws tuaj yeem siv rau ntau yam kev sib cais crystallization thiab catalytic reactions, thiab kuj tuaj yeem siv rau kev npaj thiab dispersion technology ntawm ntau yam inorganic calcium sulfur polymers. Hauv kev ua cov mining, phthalic anhydride tuaj yeem siv rau kev ua cov minerals ntawm cov ore deposits los txhim kho kev ua haujlwm mining thiab zoo ntawm ore. Tsis tas li ntawd, phthalic anhydride kuj tuaj yeem siv ua cov khoom siv raw rau cov tshuaj tua kab thiab tshuaj tua kab, ua lub luag haujlwm tseem ceeb hauv kev ua kom cov qoob loo loj hlob thiab nce cov qoob loo.

Hauv kev tsim khoom lag luam, phthalic anhydride feem ntau yog siv ua cov kuab tshuaj thiab cov tshuaj rho tawm. Vim nws qhov kub qis thiab solubility siab, phthalic anhydride yog siv dav hauv kev lag luam roj av thiab kev lag luam petrochemical ua cov khoom siv tawg. Tib lub sijhawm, nws kuj tseem siv tau ua cov tshuaj chromatographic analysis reagent thiab cov tshuaj rho tawm rau cov txuj lom, thiab lwm yam, muab cov txheej txheem zoo rau kev tshuaj xyuas tshuaj lom neeg thiab kev rho tawm txuj lom.

Tsis tas li ntawd xwb, phthalic anhydride kuj siv tau los npaj vanillin, txiav txim siab txog cov piam thaj hauv zis, npaj ntau yam synergists thiab antifreeze, thiab lwm yam. Nws kuj yog ib qho ntawm cov khoom siv raw rau kev ua polyvinyl chloride stabilizers thiab yog ib qho kev xaiv zoo rau kev kho cov hlau nto. Hauv kev tsim roj hmab thiab yas, phthalic anhydride siv tau los ua cov roj hmab ntxiv thiab cov yas ntxiv los txhim kho kev ua haujlwm thiab zoo ntawm cov khoom.
