Mawu Oyamba
4-Methyl-4-(methylthio) pentane-2-one, yomwe imatchedwanso MPTK, ndi organic compound. Zotsatirazi ndizofotokozera mwatsatanetsatane za chilengedwe, kagwiritsidwe ntchito, njira yopangira ndi chitetezo cha MPTK:
Ubwino:
- Maonekedwe: MPTK imawoneka ngati makhiristo opanda mtundu kapena opepuka achikasu.
- Kusungunuka: MPTK imasungunuka mu zosungunulira zina, monga ether ndi chloroform, koma osasungunuka m'madzi.
Gwiritsani ntchito:
- Chemical kaphatikizidwe: MPTK angagwiritsidwe ntchito ngati wapakatikati mu organic kaphatikizidwe kaphatikizidwe zina organic mankhwala.
- Mankhwala ophera tizirombo: MPTK itha kugwiritsidwanso ntchito ngati mankhwala ophera tizilombo paulimi.
Njira:
- MPTK nthawi zambiri imapezedwa ndi machitidwe a sulfide okhala ndi alkyl halides. Thioalkane yofananira imapezedwa pochita alkyl halide ndi chitsulo sulfide (mwachitsanzo, sodium methyl mercaptan). Kenako, pochita thioalkane ndi acetic anhydride ndi asidi chloride, chomaliza cha MPTK chimapangidwa.
Zambiri Zachitetezo:
- MPTK iyenera kusungidwa kutali ndi kutentha kwakukulu ndi malawi otseguka, ndikusungidwa pamalo ozizira, owuma osindikizidwa ndi osindikizidwa.
- Valani zida zoyenera zodzitetezera, kuphatikiza magalasi oteteza mankhwala ndi magolovesi, mukamagwiritsa ntchito MPTK kupewa kukhudza khungu ndi maso.
- Chisamaliro chiyenera kutengedwa kuti musapume fumbi kapena nthunzi pogwira MPTK, ndipo zopumira ziyenera kuvalidwa ngati kuli kofunikira.
- Ngati mwalowa mwangozi kapena mutakumana ndi MPTK, fufuzani chithandizo chamankhwala ndikunyamula zolembera kapena zolemba kuti adokotala adziwe zomwe zili.
