Mawu Oyamba
Butyl mercaptan ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, njira zopangira ndi chitetezo:
Ubwino:
- Maonekedwe: Butyl mercaptan ndi madzi achikasu opepuka opanda mtundu komanso onunkhira kwambiri.
- Kusungunuka: Butyl mercaptan imatha kusungunuka ndi madzi, ma alcohols ndi ma ether, ndikuchitapo kanthu ndi zinthu za acidic ndi zamchere.
- Kukhazikika: Butyl mercaptan ndi yokhazikika mumpweya, koma imachita ndi mpweya kupanga ma sulfure oxides.
Gwiritsani ntchito:
- Chemical reagents: Butyl mercaptan itha kugwiritsidwa ntchito ngati vulcanizing agent ndipo nthawi zambiri imagwiritsidwa ntchito popanga organic synthesis.
Njira:
Pali njira zingapo zokonzekera butyl mercaptan, kuphatikiza njira ziwiri zodziwika bwino:
- Kuphatikiza kwa ethylene ku sulfure: Pochita ethylene ndi sulfure, butyl mercaptan ikhoza kukonzedwa poyang'anira momwe kutentha ndi nthawi yochitira.
- Sulfation reaction ya butanol: butanol imatha kupezeka pochita butanol ndi hydrogen sulfide kapena sodium sulfide.
Zambiri Zachitetezo:
- Kusasunthika kwambiri: Butyl mercaptan imakhala ndi kusinthasintha kwakukulu komanso fungo lamphamvu, ndipo kupuma kwa mpweya wochuluka kuyenera kupewedwa.
- Kukwiyitsa: Butyl mercaptan imakhudza khungu, maso ndi kupuma, choncho iyenera kutsukidwa ndi madzi pakapita nthawi mutatha kukhudzana, ndipo kukhudzana kapena kutulutsa mpweya wambiri kuyenera kupewedwa.
- Poizoni: Butyl mercaptan imatha kukhala ndi poizoni m'thupi la munthu pamlingo waukulu, ndipo chidwi chiyenera kuperekedwa kuchitetezo chakugwiritsa ntchito ndi kusungirako.
Mukamagwiritsa ntchito butyl mercaptan, njira zoyendetsera mankhwala oyenerera ziyenera kutsatiridwa ndipo zida zoyenera zotetezera monga magolovesi, magalasi ndi zovala zotetezera ziyenera kuperekedwa.
