2-(4-Methyl-5-thiazolyl)ethyl hexanoate (CAS#94159-32-7)
Mawu Oyamba
4-Methyl-5-thiazolylethanol hexanoate, yomwe imadziwikanso kuti MTBE (Methyl tert-butyl ether), ndi madzi opanda mtundu omwe ali ndi fungo lapadera. Zotsatirazi ndizofotokozera za chikhalidwe chake, kagwiritsidwe ntchito, njira yopangira ndi chidziwitso cha chitetezo:
Ubwino:
Amasungunuka mu zosungunulira zambiri monga ma alcohols, ethers, ndi ketoni, koma pafupifupi osasungunuka m'madzi.
MTBE ili ndi machitidwe oletsa kugogoda ndipo imatha kugwiritsidwa ntchito ngati anti-kugogoda pa petulo.
Gwiritsani ntchito:
MTBE imagwiritsidwa ntchito makamaka ngati chowonjezera cha petulo kuti awonjezere kukana kwa petulo, kuwongolera kuyaka kwamafuta amafuta komanso kuchepetsa mpweya woipa.
Itha kugwiritsidwanso ntchito ngati zosungunulira ndipo imakhala ndi ntchito zina pakuphatikizika kwamankhwala, kusanthula kwamankhwala ndi magawo ena.
Njira:
Kukonzekera kwa MTBE nthawi zambiri kumachitika ndi condensation zomwe isopropanol ndi methanol pansi pa acidic. Njira yeniyeni imaphatikizapo kuchitapo kanthu kwa isopropanol ndi methanol pamaso pa chothandizira cha asidi (mwachitsanzo, sulfuric acid) kuti apange MTBE, yomwe imayeretsedwa ndi distillation kuti ipeze mankhwala omaliza.
Zambiri Zachitetezo:
MTBE ndi madzi omwe amatha kuyaka okhala ndi malo otsika komanso kutentha kwa autoignition. Iyenera kugwiritsidwa ntchito pamalo olowera mpweya wabwino, kutali ndi malawi otseguka ndi magwero a kutentha.
Kukumana ndi mpweya wa MTBE kwa nthawi yayitali kumatha kukhala ndi zotsatira zoyipa pamapumira, maso, ndi khungu. Zida zodzitetezera zoyenerera monga zodzitetezera pa kupuma, magalasi, ndi magolovesi odzitetezera ziyenera kuvalidwa.
MTBE ndi kawopsedwe kochepa, koma sayenera kulowetsedwa kapena kukhudzidwa ndi ziwalo zamkati. Ngati mwamwa mowa mwangozi kapena kukhudza, pitani kuchipatala mwamsanga.
