Intshayelelo
I-4-Methyl-4-(methylthio) pentane-2-one, eyaziwa ngokuba yi-MPTK, i-organic compound. Oku kulandelayo yintshayelelo eneenkcukacha ngobume, ukusetyenziswa, indlela yokuvelisa kunye nolwazi lokhuseleko lweMPTK:
Umgangatho:
-Imbonakalo: I-MPTK ibonakala njengeekristale ezingenambala okanye ezikhanyayo ezityheli.
- Ukunyibilika: I-MPTK iyanyibilika kwezinye izinyibilikisi zendalo, njenge-ether kunye neklorofomu, kodwa ayinyibiliki kakuhle emanzini.
Sebenzisa:
- I-Chemical synthesis: I-MPTK ingasetyenziswa njengendawo ephakathi kwi-organic synthesis ye-synthesis yezinye izinto eziphilayo.
- Amayeza okubulala izinambuzane: IMPTK isenokusetyenziswa njengento ekrwada kwizibulali zinambuzane kwezolimo.
Indlela:
- I-MPTK idla ngokufunyanwa ngokusabela kwe-sulfides kunye ne-alkyl halides. I-thioalkane ehambelanayo ifunyenwe ngokuphendula i-alkyl halide nge-metal sulfide (umzekelo, i-sodium methyl mercaptan). Emva koko, ngokuphendula i-thioalkane nge-acetic anhydride kunye ne-acid chloride, imveliso yokugqibela ye-MPTK yenziwa.
Ulwazi ngoKhuseleko:
- I-MPTK kufuneka igcinwe kude namaqondo obushushu aphezulu kunye namadangatye avulekileyo, kwaye igcinwe kwindawo epholileyo, eyomileyo ivalwe kwaye ivalwe.
-Nxiba izixhobo ezifanelekileyo zokuzikhusela, kubandakanywa iiglasi zokukhusela iikhemikhali kunye neeglavu, xa usebenzisa iMPTK ukunqanda ukudibana ngokuthe ngqo nolusu kunye namehlo.
- Ukunyamekela kufuneka kuthathwe ukuphepha ukuphefumla uthuli okanye umphunga xa uphethe i-MPTK, kwaye ii-respirators kufuneka zigqitywe xa kuyimfuneko.
- Ukuba uginya ngengozi okanye udibana ne-MPTK, funa unyango kwaye uphathe ukupakishwa okanye ileyibhile kunye nawe ukuze ugqirha wakho akwazi ukuchonga izithako.
