Khoom Taw Qhia

Tetrachlorophthalic anhydride rau tshuaj tua kab intermediates yog ib qho tshwj xeeb organic chemical intermediate tsim tshwj xeeb rau kev tsim tshuaj tua kab. Tsis zoo li generic industrial-qib tetrachlorophthalic anhydride, qib no yog kho raws li qhov tshwj xeeb xav tau ntawm cov tshuaj tua kab nruab nrab synthesis, tshwm sim ua dawb - ntws dawb crystalline hmoov. Nws muab kev ruaj ntseg tshuaj lom neeg ruaj khov txawm tias nyob rau hauv qhov siab - cua sov, siab - cov tshuaj tiv thaiv siab ib puag ncig uas muaj nyob rau hauv ntau- cov tshuaj tua kab ntau lawm, thiab cov yam ntxwv tuned, tswj tau los txhawb cov kev hloov pauv zoo ib yam hauv cov phiaj xwm kev sib txuas. Raws li lub tuam tsev tseem ceeb rau kev tsim tshuaj tua kab nruab nrab, nws pom kev siv dav hauv kev tsim tshuaj tua kab thiab lwm yam tshuaj zoo, los ntawm cov khoom siv tiv thaiv qoob loo rau cov tshuaj tua kab kom huv, xa cov khoom siv raw zoo sib xws rau siab - zoo, kev tswj hwm - ua raws li cov tshuaj tua kab.

Cov khoom siv no ua raws li cov qauv kev lag luam tshwj xeeb rau kev siv tshuaj tua kab nruab nrab, nrog tetrachlorophthalic anhydride ua nws cov haujlwm tseem ceeb. Nws tswj hwm qhov kev ua kom huv huv tsis tu ncua, nrog kev tswj xyuas cov kab tsis huv - suav nrog cov kua qaub seem, cov hlau hnyav, thiab cov tshuaj tiv thaiv los ntawm - cov khoom uas tuaj yeem cuam tshuam cov nucleophilic hloov pauv lossis cyclization cov kauj ruam hauv kev tsim tshuaj tua kab - txwv rau qib tsawg. Nws tsis muaj pungent tsw, thiab tiv taus noo noo nqus thiab deliquescence txawm nyob rau hauv siab -humidity cia thiab ntau lawm chaw, ncaj qha txhawb cov tshuaj tiv thaiv zoo ib yam thiab xaus-intermediate stability nyob rau hauv cov tshuaj tua kab synthesis.Nws thawj siv yog ib qho tseem ceeb intermediate nyob rau hauv kev tsim ntau yam ntawm cov tshuaj tua kab upstream fungicides, xws li cov tshuaj tua kab mob rau cov tshuaj tua kab. foliar daim ntawv thov, thiab neonicotinoid insecticides rau dav -kev tiv thaiv qoob loo. Thaum siv cov tshuaj tua kab nruab nrab, cov khoom siv no txo ​​qis qhov tsis xav tau sab nraud, txhawb cov txiaj ntsig thiab purity ntawm cov hom phiaj nruab nrab, thiab ncaj qha txhim kho kev ua tau zoo thiab kev nyab xeeb ntawm cov khoom siv tshuaj tua kab kawg, ua kom tau raws li qhov xav tau ntawm siab- kawg, qis- cov tshuaj tua kab ntau lawm. Nws yog optimized rau loj - ntim, txuas ntxiv cov kab tsim tshuaj tua kab, thiab peb tuaj yeem kho cov qib purity, impurity txwv, thiab lub cev specifications kom phim cov kev xav tau tshwj xeeb ntawm txhua tus neeg siv khoom cov txheej txheem tsim khoom thiab xaus - cov khoom yuav tsum tau ua.

Peb tau tsim ib txhais tes-rau, batch- cov txheej txheem tswj kev ua tau zoo los xyuas kom meej tias cov khoom no ua tau raws li cov kev xav tau ntawm cov tshuaj tua kab nruab nrab, tsis yog kev cia siab rau cov khoom siv dav dav, ib qho - loj- haum- tag nrho cov kev tswj hwm. Peb qhov kev tswj hwm zoo pib ntawm kev muab cov khoom siv raw: txhua qhov khoom noj khoom haus tuaj yeem raug kuaj tawm tsam cov tshuaj tua kab- cov qauv tshwj xeeb, thiab tsuas yog cov khoom uas ua tau raws li peb cov kev cai qib tshuaj zoo rau kev tsim tshuaj tua kab yog pom zoo siv. Txhua kauj ruam tseem ceeb hauv cov txheej txheem tsim khoom - los ntawm cov tshuaj tiv thaiv thiab crystallization mus rau ziab thiab ntim - muaj nyob rau hauv - kab, tiag - lub sij hawm sim mus ntes batch variations thaum ntxov, thiab tiv thaiv cross- kis kab mob los yog pliaj impurity introduction.Txhua batch ntawm Tetrachlorophthalic anhydride rau tshuaj tua kab intermediates {2} mus rau compparameters multimediates ua ntej nws yog cleared rau cov khoom xa tuaj. Peb xyuas tsis yog tsuas yog purity purity thiab impurity theem, tab sis kuj muaj cov ntsiab lus noo noo, melting point, reactivity nyob rau hauv ib tug simulated tshuaj tua kab synthesis ib puag ncig, thiab ntev - lub sij hawm cia stability. Rau txhua batch peb nkoj, peb muab tag nrho, official, batch-cov ntaub ntawv xeem tshwj xeeb uas suav nrog tag nrho cov ntaub ntawv tseem ceeb, nrog rau tag nrho traceability rov qab mus rau thawj raw khoom ntau ntau. Qhov no tsom, kev tsim khoom- txheej txheem tswj kev ua tau zoo tau txais kev ntseeg siab ntawm cov tuam txhab lag luam agrochemical thoob ntiaj teb, thiab tsim lub hauv paus ntawm peb lub sijhawm ntev -, kev sib koom tes ntawm cov neeg siv khoom ruaj khov.
