Methanol ndiisopropanolndi zosungunulira ziwiri zomwe zimagwiritsidwa ntchito m'mafakitale.Ngakhale kuti amagawana zofanana, amakhalanso ndi zinthu zosiyana ndi zomwe zimawasiyanitsa.M'nkhaniyi, tikambirana za zosungunulira ziwirizi, kufananiza ndi thupi ndi mankhwala, komanso momwe amagwiritsira ntchito komanso mbiri yachitetezo.

Tiyeni tiyambe ndi methanol, yomwe imadziwikanso kuti mowa wamatabwa.Ndi madzi omveka bwino, opanda mtundu omwe amasakanikirana ndi madzi.Methanol ali ndi otsika kuwira mfundo 65 digiri Celsius, zomwe zimapangitsa kukhala oyenera ntchito otsika kutentha ntchito.Ili ndi kuchuluka kwa octane, zomwe zikutanthauza kuti zitha kugwiritsidwa ntchito ngati zosungunulira komanso anti-knock agent mu mafuta.

Methanol imagwiritsidwanso ntchito ngati chakudya popanga mankhwala ena, monga formaldehyde ndi dimethyl ether.Amagwiritsidwanso ntchito popanga biodiesel, gwero lamafuta ongowonjezwdwa.Kuphatikiza pa ntchito zamakampani, methanol imagwiritsidwanso ntchito popanga ma varnish ndi ma lacquers.

Tsopano tiyeni tiyang'ane ku isopropanol, yomwe imadziwikanso kuti 2-propanol kapena dimethyl ether.Zosungunulirazi zimakhalanso zomveka bwino komanso zopanda mtundu, zokhala ndi malo otentha pang'ono kuposa methanol pa 82 digiri Celsius.Isopropanol imasakanikirana kwambiri ndi madzi ndi lipids, zomwe zimapangitsa kuti zikhale zosungunulira zabwino kwambiri pakugwiritsa ntchito mitundu yosiyanasiyana.Amagwiritsidwa ntchito kwambiri ngati chodulira muzopaka utoto komanso kupanga magolovesi a latex.Isopropanol imagwiritsidwanso ntchito popanga zomatira, zosindikizira, ndi ma polima ena.

Pankhani ya chitetezo, methanol ndi isopropanol ali ndi zoopsa zawo zapadera.Methanol ndi poizoni ndipo imatha kuyambitsa khungu ngati itawazidwa m'maso kapena kumeza.Zimakhalanso zoyaka kwambiri komanso zimaphulika zikasakanikirana ndi mpweya.Kumbali ina, isopropanol imakhala ndi mphamvu yoyaka moto ndipo imakhala yochepa kwambiri kuposa methanol ikasakanikirana ndi mpweya.Komabe, imayakabe ndipo iyenera kugwiridwa mosamala.

Pomaliza, methanol ndi isopropanol ndi zosungunulira zamtengo wapatali zamafakitale zomwe zili ndi katundu wawo wapadera komanso ntchito.Kusankha pakati pawo kumadalira zofunikira zenizeni za ntchito ndi mbiri yachitetezo cha zosungunulira zilizonse.Methanol imakhala ndi malo otsika owira ndipo imaphulika kwambiri, pamene isopropanol imakhala ndi malo otentha kwambiri ndipo imakhala yochepa kwambiri koma imatha kuyaka.Posankha zosungunulira, ndikofunika kulingalira zakuthupi zake, kukhazikika kwa mankhwala, kawopsedwe, ndi mbiri yoyaka moto kuti zitsimikizidwe kuti zikugwiritsidwa ntchito moyenera komanso moyenera.
