Cov Ntawv Thov
1. Nruab nrab hauv cov khoom siv hauv nruab nrog cev
Cov tshuaj nruab nrab: 3-nitrophthalic acid yog siv los ua lub tsev thaiv kom synthesizing cov kab ke, suav nrog kev sib txuas rau cov tshuaj hauv cov tshuaj.
Zoov Intermediates: Nws ua haujlwm ua ntej ua ntej ntawm Azo Dyes, uas cov pab pawg Nitro tuaj yeem raug txo rau txoj kev hloov pauv ntawm kev couplings.
Agnochemical intermediates: nws yog siv nyob rau hauv synthesis ntawm cov tshuaj tua kab, fungicides, thiab tshuaj tua kab.
2. Polymer thiab Resin Synthesis
Siv nyob rau hauv kev npaj cov kev tshwj xeeb polyimides, polyesters, lossis copolymers, tshwj xeeb thaum ua haujlwm ntawm cov ntaub ntawv uas xav tau rau cov khoom siv thermal thiab tshuab hluav taws xob.
Tus neeg sawv cev hla: Cov pab pawg carboxyl tuaj yeem tsim cov pab pawg lossis kev sib txuas ua ke hauv cov polymers, txhim kho kev ntawj ntom ntom thiab txhim kho lub cev lub cev.
3. Ligand thiab Kev Koom Tes Ua Haujlwm
Cov compound tuaj yeem siv los siv cov nkauj chelands vim muaj cov kev ua haujlwm ntawm cov hlau roj carboxylic, uas tuaj yeem ua haujlwm rau cov hlau hauv catalyst los yog mof (hlau-organic.
Hauv kev sib koom ua ke cov polymers thiab suprramolecular chemistry, nws ua raws li txoj kev sib txuas ntawm txoj kev tsim kho cov txheej txheem.
4. Kev txo cov khoom rau amino derivatives
Thaum txo qis ntawm Nitro Group (piv txwv li, catalytic hydrogenation), nws yields 3-aminophalic acid, ib qho tseem ceeb hauv nruab nrab thiab cov fluorescent sib xyaw.
Cov txiaj ntsig
Cov pab pawg ua haujlwm ntau yam: muaj ob pawg hluav taws xob-rho tawm (NOTOR) thiab acidic (COoh) pawg, ua kom muaj kev sib txuam ntawm cov tshuaj lom neeg.
Thermal Stability: nws cov qauv qub ua rau nws haum rau cov ntawv thov high-kub-kub polymer.
Txhim kho solubility hauv polar solvents: vim nws cov pab pawg polar, nws dissolves zoo hauv cov kuab tshuaj zoo li DMOPS, DMF, lossis aqueous alkaline daws.
Muaj txiaj ntsig prefursor rau cov molecules: tso cai tsim cov lwg me me nrog cov hluav taws xob tshwj xeeb, kho qhov muag, lossis kev sib koom tes.
Eco-cov phooj ywg hloov hauv DYES: Nitro-ua haujlwm ua ntej ua ntej txo qhov xav tau kev lom zem hlau kom ntau thaum hloov mus rau Azo Dyes.
Tag
3-nitrophthalic acid (CAS li 603-11-2) yog qhov muaj txiaj ntsig tshwj xeeb tshuaj, dav siv los ua hluav taws xob nruab nrab hauv cov khoom siv hluav taws xob, thiab cov ntaub ntawv siab. Nws dual carboxylic acid ua haujlwm thiab Nitro Pab Pawg muaj cov tshuaj muaj txiaj ntsig zoo, tso cai ua cov ntsiab lus tseem ceeb hauv kev tshawb fawb thiab kev siv tshuaj. Nws cov ntawv thov nyob rau hauv polymers, coordination sib sau, thiab zoo tshuaj lom neeg ua rau nws tsis muaj tshuaj sib txuas ua ke hauv cov hluavtis thiab cov khoom siv chemists niaj hnub.
