Zambiri
P-hydroxypropionone, yomwe imadziwikanso kuti 3-hydroxy-1-phenylpropiotone kapena vanillin, ndi mankhwala achilengedwe. Zotsatirazi zikufotokoza za katundu wake, ntchito, njira zopangira ndi chidziwitso cha chitetezo:
Ubwino:
Hydroxypropiophenone ndi kristalo wolimba, nthawi zambiri woyera kapena wachikasu wonyezimira. Ili ndi fungo lokoma ndipo nthawi zambiri imagwiritsidwa ntchito ngati zokometsera. Pawiri izi ali mkulu kusungunuka kutentha firiji ndipo akhoza sungunuka m'madzi ndi zambiri organic solvents.
Gwiritsani ntchito:
Njira:
P-hydroxypropion nthawi zambiri imakonzedwa ndi kaphatikizidwe ka mankhwala. Njira yodziwika bwino imapezedwa ndi esterification ya cresol ndi acetone, kutsatiridwa ndi desulfation ndi kutentha zinthu za esterification.
Zambiri Zachitetezo:
Hydroxypropiophenone nthawi zambiri imadziwika kuti ndi yotetezeka. Kuwonekera kwambiri kungayambitse khungu ndi maso. Kusamala monga magolovesi, magalasi, ndi zovala zoyenera zogwirira ntchito ziyenera kuchitidwa pogwiritsira ntchito kapena pogwira. Pewani kulowetsa fumbi kapena nthunzi yake ndipo onetsetsani kuti ikugwira ntchito pamalo abwino mpweya wabwino. Mukamwedwa kapena kukhudzidwa, pitani kuchipatala msanga.
