Chiyambi
Methyl tert-butyl ether (MTBE) kale inkaonedwa ngati gawo la mafuta lopanda lead lomwe silingasinthidwe ndipo linkatchedwa "petrochemical ya m'badwo wachitatu" m'zaka za m'ma 1980. Chifukwa imatha kuwonjezera kuchuluka kwa mpweya mu mafuta osagwiritsa ntchito lead, kupangitsa mafuta kuyaka bwino, kuchepetsa kutulutsa zinthu zoopsa monga carbon monoxide ndi benzene, komanso ikhoza kusintha tetraethyl lead ngati choletsa chisokonezo, imakwaniritsa zofunikira popanga mafuta osagwiritsa ntchito lead ambiri. , zomwe zimapangitsa kuti kufunika kwake kukule mofulumira, ndi chowonjezera chabwino kwambiri cha mafuta octane cha Chemicalbook. MTBE ndi gawo labwino kwambiri losakaniza popanga mafuta osagwiritsa ntchito lead, octane wambiri, komanso okosijeni. Sichingowonjezera kuchuluka kwa octane kokha, komanso chimawongolera magwiridwe antchito a magalimoto, kuchepetsa kuchuluka kwa CO mu mpweya wotulutsa utsi, ndikuchepetsa ndalama zopangira mafuta. Kuphatikiza apo, methyl tert-butyl ether ndi chinthu chofunikira kwambiri cha mankhwala, chomwe chingasinthidwe kukhala isobutylene ndikugwiritsidwa ntchito ngati zopangira rabara ndi mankhwala ena. Koma pakadali pano, MTBE ikuoneka kuti ikuchepetsa mphamvu zake.

Kapangidwe ka thupi ndi mankhwala:
Methyl tert-butyl ether, yomwe chidule chake ndi MTBE (methyltert-butylether), imakhala ndi kutentha kwa -109°C ndipo kutentha kwa 55.2°C. Ndi madzi opanda mtundu, owonekera bwino, okhala ndi octane yambiri okhala ndi fungo lofanana ndi ether. Yapangidwa Chemicalbook ndi chinthu chabwino kwambiri chosakaniza mafuta opanda lead, okhala ndi octane yambiri, komanso okosijeni, ndipo yakhala ikugwiritsidwa ntchito kwambiri ngati chowonjezera cha petulo padziko lonse lapansi. Sikuti imangowonjezera kuchuluka kwa octane ya petulo, komanso imathandizira magwiridwe antchito a magalimoto, kuchepetsa kuchuluka kwa CO mu mpweya wotulutsa utsi, ndikuchepetsa ndalama zopangira petulo.
Kagwiritsidwe Ntchito
Methyl tert-butyl ether (MTBE) imagwiritsidwa ntchito kwambiri ngati chowonjezera cha petulo ndipo ili ndi mphamvu zabwino kwambiri zoletsa kugwedezeka. Imatha kusakanikirana bwino ndi petulo, imayamwa madzi ochepa, ndipo siipitsa chilengedwe. MTBE imatha kukonza mawonekedwe oyambira ozizira komanso magwiridwe antchito othamanga a petulo popanda zotsatirapo zoyipa pa kutseka kwa nthunzi.
