Txoj kev raug rau khaws cia txiv neej anhydride

Txoj hauv kev zoo rau khaws cia txiv neej anhydride feem ntau suav nrog cov ntsiab lus hauv qab no:
Tsis tshua muaj kub cia: Qhov ntsuas kub ntawm maleic anhydride feem ntau tsis tshaj 30 degree. Nws raug nquahu kom khaws cia qis dua 4 degree kom ncua sijhawm cia. Hauv qhov chaw txias dua (xws li hauv qab -18 degree), nws lub neej txee tuaj yeem txuas ntxiv mus ntev.
Kev cia qhuav: Maleic anhydride yog qhov ua rau deliquescence thiab yuav tsum tau muab cia rau hauv qhov chaw qhuav. Cov neeg ua kom qhuav los yog cov hnab ntim ntim tau siv tau rau ntim kom nws qhuav.
Tsaus cia: Maleic anhydride yog qhov yooj yim rau photodegradation thiab yuav tsum muab cia rau hauv qhov chaw tsaus kom tsis txhob raug lub teeb ntev.
Tsis txhob sib cuag nrog lwm cov organic tshuaj: Maleic anhydride muaj zog reactivity thiab yuav tsum tau zam los ntawm kev sib cuag nrog lwm cov organic tshuaj kom tsis txhob muaj xwm txheej. Tshwj xeeb, nws yuav tsum tau muab cais tawm ntawm cov oxidants, txo cov neeg ua haujlwm, cov kua qaub, thiab cov tshuaj noj tau, thiab kev sib xyaw cia yuav tsum zam.
Kev tiv thaiv hluav taws kub thiab tawg: Maleic anhydride yog nplaim taws thiab yuav tsum muab cia kom deb ntawm qhov hluav taws kub thiab qhov chaw kub. Nyob rau tib lub sijhawm, lub thawv ntim khoom yuav tsum tau muab kaw kom tsis txhob xau.
Kev tshuaj xyuas tsis tu ncua: Tshawb xyuas cov thawv ntim khoom kom tsis tu ncua, kev sib khi, thiab lwm yam teeb meem. Yog tias pom muaj qhov txawv txav, lawv yuav tsum tau kho kom raws sijhawm kom tsis txhob muaj kev puas tsuaj rau cov txiv neej anhydride.
Nruab nrog cov khoom siv tua hluav taws: Cov chaw cia khoom yuav tsum tau nruab nrog cov khoom siv hluav taws xob tsim nyog los teb tam sim thaum muaj hluav taws kub.
Tsis tas li ntawd, kev ntim khoom ntawm maleic anhydride tuaj yeem ua tiav los ntawm kev siv cov hnab yas sab hauv, cov hnab ntim sab nrauv, cov nruas hlau, cov nruas ntoo, thiab lwm yam los tiv thaiv los nag thiab tshav ntuj.
Cov ntaub ntawv saum toj no tsuas yog siv rau kev siv xwb, thiab cov txheej txheem khaws cia tshwj xeeb yuav txawv nyob ntawm qhov xwm txheej tiag tiag. Thaum khaws cia maleic anhydride, cov kev cai cuam tshuam thiab cov txheej txheem kev nyab xeeb yuav tsum tau ua raws li nruj me ntsis kom ntseeg tau tias kev ruaj ntseg cia.
