Ulwazi
I-P-hydroxypropionone, eyaziwa ngokuba yi-3-hydroxy-1-phenylpropiotone okanye i-vanillin, i-organic compound. Oku kulandelayo kuchaza iipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
IHydroxypropiophenone yikristale eyomeleleyo, idla ngokuba mhlophe okanye tyheli ngombala okhanyayo. Inevumba elimnandi kwaye isoloko isetyenziswa njengesiqholo. Le khompawundi ine-solubility ephezulu kwiqondo lobushushu begumbi kwaye inokunyibilika emanzini kunye nezinyibilikisi ezininzi eziphilayo.
Sebenzisa:
Indlela:
I-P-hydroxypropion idla ngokulungiswa nge-chemical synthesis. Indlela eqhelekileyo ifunyenwe nge-esterification ye-cresol kunye ne-acetone, ilandelwa yi-desulfation ngokufudumeza iimveliso ze-esterification.
Ulwazi ngoKhuseleko:
IHydroxypropiophenone ngokuqhelekileyo ithathwa njengekhompawundi ekhuselekileyo. Ukuba sesichengeni okugqithisileyo kunokubangela ulusu kunye nokucaphuka kwamehlo. Izilumkiso ezinjengeeglavu, iiglasi, kunye nempahla yokusebenza efanelekileyo ifanele ithathwe xa usebenzisa okanye uphethe. Kuphephe ukuphefumla uthuli lwayo okanye umphunga kwaye uqinisekise ukuba usebenza kwindawo engena umoya. Kwimeko yokusela okanye ukuvezwa, funa unyango olukhawulezileyo.
