Los ntawm kev kawm ntxiv, cov txheej txheem hydrolysis ntawm NVP nyob rau hauv lub xub ntiag ntawm acrylic acid los yog KSO tau txais. Lub vinyl nqi imbalance nyob rau hauv NVP molecule, piv txwv li, tus nqi ceev ntawm ob carbon atoms txuas los ntawm ob daim ntawv cog lus sib txawv. Qhov kev tsis txaus siab no muab qhov ua tau rau hydrolysis ntawm NVP. Thaum cov kua qaub lossis alkali hlau ions tshwm sim, NVP cov molecules yog isomerization, tsim cov kev hloov pauv ntawm lub xeev, thiab thaum kawg tsim pyrrolidone thiab acetaldehyde, uas yog ib kauj ruam ntawm NVP hydrolysis. Ob-kauj ruam hydrolysis ntawm NVP yog qhov sib ntxiv ntawm ib-kauj ruam pyrrolidone nrog NVP molecules, thiab tom qab ntawd ntxiv decomposes rau hauv pyrrolidone thiab acetaldehyde nyob rau hauv lub xub ntiag ntawm dej. Los ntawm qhov kev xav ntawm NVP hydrolysis mechanism, seb NVP tuaj yeem hydrolyzed nyob ntawm seb puas muaj cov kev hloov pauv hauv lub xeev tuaj yeem tsim, lossis seb cov tshuaj tiv thaiv intramolecular isomerization ntawm NVP yog tus yuam sij rau seb NVP puas yog hydrolyzed.
Txij li thaum NVP yooj yim rau hydrolyze, ob lub ntsiab lus yuav tsum tau them nyiaj mloog rau hauv kev tsim thiab siv NVP: ua ntej, dej yuav tsum tau muab tshem tawm thaum lub sij hawm synthesis ntawm NVP kom ntseeg tau tias tsis muaj dej hauv cov khoom. Qhov thib ob yog tias nyob rau hauv cov txheej txheem ntawm kev khaws cia thiab kev thauj mus los, ua kom cov khoom nruab nrab lossis tsis muaj zog alkaline, txhawm rau tiv thaiv hydrolysis thiab nws tus kheej-polymerization, txoj kev ib txwm yog ntxiv 0.1% alkali xws li sodium hydroxide, ammonia lossis qis molecular hnyav. amines.
