Mankhwala a mowa ndi mtundu wa organic pawiri womwe uli ndi gulu la hydroxyl (-OH) lomangika ku atomu ya kaboni.Amagwiritsidwa ntchito kwambiri m'mafakitale monga mankhwala, zodzoladzola, ndi kupanga mafuta.Ethanol, methanol, ndi propanol ndi ena mwa mowa omwe amagwiritsidwa ntchito kwambiri.Mowa umapezeka kawirikawiri m’zakumwa zoledzeretsa ndipo umagwiritsidwa ntchito ngati zosungunulira, mafuta, ndi zopha tizilombo.Methanol imagwiritsidwa ntchito ngati zosungunulira ndi mafuta, ndipo propanol imagwiritsidwa ntchito kwambiri muzodzola ndi mankhwala.Mowa uli ndi zinthu zosiyanasiyana zakuthupi ndi zamankhwala zomwe zimapangitsa kuti zikhale zofunikira m'mafakitale ambiri.Komabe, zimatha kukhala zapoizoni komanso zoyaka moto, zomwe zimapangitsa kuti zikhale zowopsa ngati sizikugwiridwa bwino.
