Ulwazi
I-P-hydroxypropionone, eyaziwa nangokuthi i-3-hydroxy-1-phenylpropiotone noma i-vanillin, iyinhlanganisela yezinto eziphilayo. Okulandelayo kuchaza izakhiwo zayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
IHydroxypropiophenone iyikristalu eqinile, ngokuvamile emhlophe noma ephuzi ngokukhanyayo ngombala. Inephunga elimnandi futhi ivame ukusetshenziswa njengesinongo. Le nhlanganisela ine-solubility ephezulu ekamelweni lokushisa futhi ingancibilika emanzini kanye nezincibilikisi eziningi eziphilayo.
Sebenzisa:
Indlela:
I-P-hydroxypropion ivame ukulungiswa ngamakhemikhali. Indlela evamile itholakala ngokufakwa kwe-esterification kwe-cresol ne-acetone, okulandelwa ukukhishwa kwe-sulfate ngokushisisa imikhiqizo ye-esterification.
Ulwazi Lokuphepha:
I-Hydroxypropiophenone ngokuvamile ibhekwa njengenhlanganisela ephephile uma kuqhathaniswa. Ukuchayeka ngokweqile kungase kubangele ukulunywa kwesikhumba namehlo. Izinyathelo zokuphepha ezinjengamagilavu, izibuko, nezingubo zokusebenza ezifanele kufanele zithathwe lapho usebenzisa noma uphatha. Gwema ukuhogela uthuli noma umhwamuko wayo futhi uqiniseke ukuthi usebenza endaweni enomoya omuhle. Esimeni sokumunca noma ukuchayeka, funa usizo lwezokwelapha ngokushesha.
