Cov lus qhia:
Siv nyob rau hauv cov organic synthesis, tshuaj tua kab thiab tshuaj intermediates.Nws yog siv nyob rau hauv cov hluavtaws vinyl tshuaj tua kab, plaub tsiaj felting xov, tshuaj dawb, decolorization, tshwj xeeb, kom tsis muaj menyuam, tshuaj tua kab, thiab lwm yam.
Cov kev ua haujlwm ceev faj: kaw cov haujlwm, saib xyuas qhov cua. Cov tswj hwm yuav tsum tau txais kev cob qhia tshwj xeeb thiab nruj me ntsis los ntawm cov txheej txheem kev ua haujlwm. Nws raug nquahu kom cov neeg ua haujlwm hnav lub ntsej muag tus kheej lim cov roj ua kua roj (daim npog tag nrho), roj hmab kua qaub thiab alkali tiv thaiv cov khaub ncaws thiab roj hmab kua qaub thiab cov hnab looj tes tiv thaiv alkali. Cia kom deb ntawm hluav taws thiab qhov kub. Tsis haus luam yeeb hauv chaw ua haujlwm. Siv tawg ua pov thawj uas muaj cua tshuab thiab cuab yeej siv. Zam kev haus luam yeeb. Tiv thaiv kev kub nyhiab thiab pa ncho mus rau cov cua ua haujlwm. Zam kev sib cuag nrog oxidant, alkali thiab dej cawv. Hauv kev tshwj xeeb, zam kev sib cuag nrog dej. Thaum nqa khoom, nws yuav tsum thauj khoom thiab thau khoom me ntsis kom thiaj li tiv thaiv cov pob thiab ntim khoom los ntawm kev puas tsuaj. Cov twj tua hluav taws ntawm ntau yam khoom thiab qhov ntau thiab cov khoom siv rau thaum muaj xwm txheej ceev yuav tsum tau muab. Cov thawv ntim tsis huv yuav muaj cov tshuaj tsis haum.
Kev xyuam xim khaws cia: khaws cia hauv ib qho chaw txias, qhuav thiab ua cua huv zoo hauv cov khoom. Cia kom deb ntawm hluav taws thiab qhov kub. Khaws lub taub ntim cia. Nws yuav tsum muab khaws cia cais tawm ntawm oxidants, alkalis thiab cawv, thiab kev sib xyaw ua ke yuav tsum zam. Cov twj siv hluav taws ntawm ntau yam thiab ntau thiab tsawg yuav tsum raug muab. Qhov chaw ntim khoom yuav tsum muaj cov cuab yeej siv kho mob lub sij hawm tiv thaiv kev kub ntxhov thiab cov khoom lag luam kom zoo.
Txoj kev ntau lawm: cov txheej txheem ntau cov txheej txheem tuaj yeem siv rau hauv cov txheej txheem npaj. Cov khoom lag luam tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm dichloroacetic acid nrog chlorosulfonic acid, cov tshuaj tiv thaiv ntawm chloroform nrog carbon monoxide catalyzed los ntawm anhydrous aluminium trichloride, cov tshuaj tiv thaiv ntawm dichloroacetic acid nrog phosgene hauv dimethylformamide, thiab oxidation ntawm trichlorethylene. Trichlorethylene thiab azodiisobutyronitrile (catalyst) tau rhaub mus rau 100 ℃, oxygen tau qhia, thiab cov tshuaj tiv thaiv tau ua raws li lub siab ntawm 0.6MPa. Cov roj da dej kub tau tswj nyob rau ntawm 110 ℃ rau 10h, thiab dichloroacetyl chloride tau yaj hauv qab lub siab. Cov khoom ua los ntawm trichlorethylene oxide kuj tseem tuaj yeem hloov mus rau hauv dichloroacetyl chloride los ntawm cov tshuaj tiv thaiv nrog methylamine, triethylamine, pyridine thiab lwm yam amines.
