N-butanol ni chinthu chakuzirwa chomene chakupangika na kemiko, chomenechomene icho chikugwiriskirika nchito pakupanga mtundu wa mtundu wa mtundu, phthalate, dibuttyl, butyline, ethylene glycol monobutyl ether na vinthu vinyake vyakukhira, ivyo vikugwiriskirika nchito chomene mu vyakuvwara, vyakuvwara Agents, salutizes, pulasitiki na vinyake vya mu minda. N-butal ni nakoso mafuta, biochemicals na vyakununkhira, vyakuwonjezera vya penti ya alky, ndiposo vikugwiriskirika nchito pakupanga vinthu vya surfactant .
Mu vyaka vyasonosono apa, mafakitale gha vyakuvwara vya mu charu ichi ghapangika mwaluŵiro, ndipo mabizinesi ghakuphimba gha pa nyumba nagho ghakukura . Iwo ŵakukwaniska kupanga na kupanga vinthu vyakupambanapambana vyapachanya . Kweni, kukura kwa vyakufumamo vyakukhira vya n-butaol na mtengo wakusazgikira wakusazgikira na vinthu vyapachanya vyaluso vichalipo ku vyaru vinyake . Kugaŵikana kwa larger, vinyake vyakufumamo na ntchito zapadera ndipo mtengo wakusazgikira ukukhumbikwira kutumizgika .
