Intshayelelo
I-4-Hydroxy-3-methylacetophenone, eyaziwa ngokuba yi-4-hydro-3-methyl-1-phenyl-2-butanone, i-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, iindlela zokwenza kunye nolwazi lokhuseleko:
Umgangatho:
I-4-Hydroxy-3-methylacetophenone ngulwelo olungenambala okanye olutyheli olunevumba elikhethekileyo. Yikhompawundi ye-polar enyibilikayo kwii-alcohol, ii-ethers, ii-ketones, kunye ne-ester solvents.
Sebenzisa:
Indlela:
Kukho iindlela ezininzi zokulungiselela i-4-hydroxy-3-methylacetophenone, kwaye enye yeendlela eziqhelekileyo ifunyenwe nge-oxidation reaction of carbonyl compounds. Amanyathelo athile abandakanya ukuphendula i-3-methylacetophenone kunye ne-iodine okanye i-sodium hydroxide ukufumana iodozolate ehambelanayo okanye i-hydroxyl, ethi iguqulelwe kwi-4-hydroxy-3-methylacetophenone ngokuphendula kokunciphisa.
Ulwazi ngoKhuseleko:
I-4-Hydroxy-3-methylacetophenone ithathwa njengento ekhuselekileyo kwizicelo eziqhelekileyo. Njengekhompawundi ephilayo, isenazo iingozi ezinokubakho. Ukudibana nolusu kunye nokuphefumla umphunga walo kunokubangela ukucaphuka kwaye kunokubangela ukungagungqi. Xa uphatha le khompawundi, kufuneka kuthathelwe ingqalelo ukusebenzisa izixhobo zokuzikhusela (ezifana neeglavu kunye nempahla yamehlo ekhuselayo) kwaye uqinisekise ukungena komoya kakuhle. Kwimeko yokudibana ngengozi okanye ukuphefumla, into leyo kufuneka ihlanjululwe okanye isuswe ngokukhawuleza kwaye kufuneka kufunwe unyango. Xa ugcina kwaye uphatha, nceda uqaphele amanyathelo okhuseleko afanelekileyo ukuphepha naziphi na iingozi.
