Intshayelelo
I-4-isobutylacetophenone, eyaziwa ngokuba yi-4-isobutylphenylacetone, i-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: I-4-Isobutylacetophenone lulwelo olungenambala, okanye lulwelo olutyheli ukuya kumdaka.
- Ukunyibilika: Kunokunyibilika okulungileyo kwizinyibilikisi eziphilayo.
- Uzinzo lokugcina: Kufuneka lugcinwe kwindawo epholileyo, eyomileyo, nengena umoya kakuhle kude nelanga elithe ngqo.
Sebenzisa:
Indlela:
- Ukulungiswa kwe-4-isobutylacetophenone ngokuqhelekileyo kufezwa nge-asidi-catalyzed alkylation. Kukho iindlela ezininzi zokulungiselela ezithile, enye yazo kukusabela i-acetophenone kunye ne-isobutanol phantsi kweemeko ze-acidic ukufumana imveliso ekujoliswe kuyo.
Ulwazi ngoKhuseleko:
- Ukunyamekela kufuneka kuthathwe ukukhusela i-4-isobutylacetophenone ekudibaneni namehlo, ulusu kunye nomgudu wokuphefumula.
-Nxiba iiglavu ezikhuselayo, iiglasi kunye nezikhuselo zobuso xa uphethe, ugcina, kwaye uphethe. Qinisekisa ukuba igumbi lingena umoya.
- Kwimeko yokudibana ngengozi kunye nekhompawundi, hlambulula ngokukhawuleza ngamanzi amaninzi ubuncinane imizuzu eyi-15 kwaye ufune unyango.
- Ulwazi oluthile lokhuseleko kufuneka lugqitywe ngokweyona meko kunye neencwadana ezifanelekileyo zokhuseleko ukuqinisekisa ukuba abaqhubi banolwazi olufanelekileyo kunye namava ekusebenzeni kovavanyo lwemichiza.
