Methanol ndiisoppanolndi mitundu iwiri yomwe imagwiritsidwa ntchito popanga mafakitale. Alinso ndi kufanana kwina, nawonso ali ndi zinthu ndi mawonekedwe omwe amawasiyanitsa. Munkhaniyi, tikambirana mwatsatanetsatane za zisungunuke ziwirizi, zikufanizira mphamvu zawo zathupi ndi mankhwala, komanso mapulogalamu awo ndi maluso awo otetezeka.

Tiyeni tiyambe ndi methanol, komwe kumadziwikanso ngati mowa wamoto. Ndi madzi osalala, opanda utoto omwe ali olakwika ndi madzi. Methanol ali ndi malo owiritsa owiritsa madigiri 65 Celsius, omwe amapangitsa kuti ikhale yoyenera kugwiritsa ntchito njira zochepa. Ili ndi chiwonetsero cha octane chambiri, chomwe chimatanthawuza kuti chitha kugwiritsidwa ntchito ngati chosungunulira ndi othandizira kugogoda mu mafuta.

Methanol amagwiritsidwanso ntchito ngati chakudya chopanga mankhwala ena, monga formaldehyde ndi dimethyl ether. Amagwiranso ntchito pakupanga biodiesel, gwero lokonzanso mafuta. Kuphatikiza pa ntchito zake zamayendedwe, methal imagwiritsidwanso ntchito popanga ma vampani ndi ma and.

Tsopano tiyeni titembenuzire ku isopropanol, imadziwikanso kuti 2-propol kapena dimethyl ether. Izi zimamvekanso bwino komanso zopanda utoto, yokhala ndi malo otentha kwambiri kuposa methanol pa 82 digiri Celsius. Isoppanol ndi yolakwika kwambiri ndi madzi ndi lipids, ndikupangitsa kukhala zosungunulira bwino kwambiri pazogwiritsa ntchito zosiyanasiyana. Nthawi zambiri imagwiritsidwa ntchito ngati wothandizirana ndi utoto wowonda komanso kupanga magolovesi a latx. Isoppanol amagwiritsidwanso ntchito popanga zomatira, zosindikiza, ndi ma poizoni ena.

Ponena za chitetezo, onse methanol ndi isoppanol ali ndi zoopsa zawo zapadera. Methanol ndi poizoni ndipo imatha kuyambitsa khungu ngati ikhomedwa m'maso kapena kulowetsedwa. Imakhalanso yoyaka kwambiri komanso yophulika ikasakanikirana ndi mpweya. Kumbali inayo, isoppanol imakhala ndi mtengo wotsika kwambiri ndipo sakuphulika kuposa methanol mukasakanikirana ndi mpweya. Komabe, ndikuyakanso komanso kuyenera kusamaliridwa ndi chisamaliro.

Pomaliza, methanol ndi isoppanol ndi ofunika kwambiri mafakitale omwe ali ndi mawonekedwe awo ndi mapulogalamu awo. Kusankha pakati pawo kumatengera zofunikira mwatsatanetsatane za pulogalamuyi ndi mbiri ya chitetezo cha litence. Methanol ali ndi chowiritsa chocheperako ndipo chikukula kwambiri, pomwe isoppanol imakhala ndi malo owiritsa ndipo sakuphulika koma oyatsidwa. Mukamasankha zosungunulira, ndikofunikira kulingalira za mawonekedwe ake, kukhazikika kwamankhwala, poizoni, komanso mbiri yowoneka bwino kuti mutsimikizire bwino.
