Mawu Oyamba
Isopentenyl thiol ndi organic pawiri. Makhalidwe ake ndi awa:
1. Maonekedwe: Prenyl mercaptans ndi zakumwa zopanda mtundu kapena zachikasu zokhala ndi fungo lapadera la thienol.
2. Kusungunuka: Ma Isopentenyl mercaptans amasungunuka mu mowa, ethers, esters ndi zosungunulira zambiri za organic, koma pafupifupi osasungunuka m'madzi.
3. Kukhazikika: Pa kutentha kwa chipinda, ma prenyl mercaptans ndi okhazikika, koma amawola pansi pa kutentha kwakukulu, asidi amphamvu ndi mikhalidwe yamphamvu ya alkali.
Ntchito zazikulu za prenyl mercaptans ndi izi:
1. Kuphatikizika kwachilengedwe: Monga gawo lapakati pakupanga kwachilengedwe, kumagwiritsidwa ntchito pokonzekera magulu osiyanasiyana azinthu zachilengedwe, monga esters, ethers, ketones ndi acyl compounds.
2. Makampani a zokometsera: amagwiritsidwa ntchito ngati zokometsera ndi zonunkhira kuti apatse zinthu kununkhira kwapadera kwa mpunga.
Pali njira zingapo zokonzekera isopentenyl thiols, zofala zimaphatikizapo:
1. Amachokera ku pentadiene chloride ndi sodium hydrosulfide.
2. Zimapangidwa ndi zochita za isopretenol ndi zinthu za sulfure.
1. Isopretenyl mercaptans imakwiyitsa ndipo iyenera kupewedwa mwachindunji ndi khungu ndi maso. Magolovesi oteteza ndi magalasi ayenera kuvala mukamagwiritsa ntchito.
2. Pewani kukhudzana ndi ma oxidants amphamvu, ma asidi amphamvu ndi ma alkalis amphamvu kuti mupewe zoopsa.
3. Sungani mu chidebe chopanda mpweya kuti mupewe kutenthedwa ndi mpweya kuti muteteze kuphulika ndi kutayika kwa ntchito.
4. Gwiritsani ntchito pamalo abwino komanso kupewa kutulutsa mpweya wa isoprenyl mercaptan.
