Intshayelelo
4-Isopropylphenol.
Umgangatho:
Imbonakalo: Ikristale engenambala okanye etyheli eqinileyo.
Ivumba: Inevumba elimnandi elikhethekileyo.
Ukunyibilika: Ukunyibilika kwi-ether kunye notywala, ukunyibilika kancinane emanzini.
Sebenzisa:
Imifuniselo yemichiza: isetyenziswa njengezinyibilikisi kunye neziphakathi ekudityanisweni kwezinto eziphilayo.
Indlela:
I-4-Isopropylphenol inokulungiswa ngezi ndlela zimbini zilandelayo:
I-Isopropylphenyl i-acetone yokunciphisa utywala indlela yokunciphisa utywala: i-4-isopropylphenol ifunyenwe ngokunciphisa i-isopropylphenyl i-acetone alcohol kunye ne-hydrogen phambi kwe-catalyst.
Indlela ye-Polycondensation ye-n-octyl phenol: i-4-isopropylphenol ifunyenwe nge-polycondensation reaction ye-n-octyl phenol kunye ne-formaldehyde phantsi kweemeko ze-acidic, kwaye emva koko ilandelwa unyango olulandelayo.
Ulwazi ngoKhuseleko:
I-4-Isopropylphenol iyacaphukisa kwaye ingaba nefuthe elibi emehlweni, ulusu kunye nenkqubo yokuphefumula, kwaye kufuneka igwenywe.
Ngexesha lokusetyenziswa, kufuneka kuthathelwe ingqalelo ukuphepha ukuphefumla uthuli okanye umphunga wayo, kwaye izixhobo ezifanelekileyo zokukhusela kufuneka zinxitywe ukuqinisekisa ukungena komoya kakuhle.
Xa ugcina kunye nokuphatha, ukudibanisa kunye ne-oxidants kunye ne-acids eqinile kufuneka kugwenywe, kwaye ngexesha elifanayo, kude nokucima kunye neendawo zokushisa eziphezulu.
Kwimeko yokudibana ngengozi okanye ukungeniswa ngempazamo, funa unyango ngokukhawuleza. Ukuba kuyenzeka, yiza nesingxobo semveliso okanye ileyibhile esibhedlele ukuze ibonwe.
Landela iinkqubo ezifanelekileyo zokusebenza zokhuseleko xa usebenzisa okanye uphethe le khemikhali.
