Doro ndechimwe chezvinonyanya kunyungudutsa zvemakemikari muupenyu hwezuva nezuva.Iyo organic compound ine inokwana imwechete hydroxyl inoshanda boka (- OH) yakasanganiswa neakazara kabhoni maatomu.Zvino, zvichienderana nenhamba yekabhoni maatomu akabatana nekabhoni maatomu ane hydroxyl anoshanda mapoka, anokamurwa kuva epuraimari, echipiri uye epamusoro.Kune marudzi matatu emakemikari zvinonyungudutsa zvinowanzoshandiswa muhupenyu hwezuva nezuva.Semuyenzaniso;Methanol (primary alcohol), ethanol (primary alcohol) uye isopropanol (secondary alcohol).
Methanol
Methanol, inonziwo methanol mune mamwe mazita, ikemikari ine kemikari formula CH3OH.Imvura yakapfava, inoputika, isina ruvara, inopfuta nedoro rakasiyana-siyana kunhuwa kwakafanana ne ethanol.Methanol inowanzoshandiswa se solvent, antifreeze, formaldehyde uye mafuta ekuwedzera murabhoritari.Mukuwedzera, nekuda kwekusagadzikana kwayo, inoshandiswawo sependi yakaonda.Nekudaro, methanol icarcinogenic uye ine muchetura doro.Kana ikafemerwa kana kumedzwa, inokonzeresa kusashanda zvakanaka kwetsinga uye kufa.
Ethanol
Ethanol, inozivikanwawo se ethanol kana zviyo doro, isanganiswa, doro riri nyore rine kemikari formula C2H5OH.Imvura inodziya, inopfuta, isina ruvara ine kakunhuhwirira kwehunhu, kazhinji muchimiro chezvinwiwa zvinodhaka, sewaini kana doro.Ethanol inogona kudyiwa zvakachengeteka, asi ndapota dzivirira kunwa zvakanyanya nekuda kwekupindwa muropa kwayo.Ethanol inoshandiswawo se organic solvent, chinhu chakakosha chedhayi uye pigment zvigadzirwa, zvizorwa nemishonga yekugadzira.
Isopropyl doro
Isopropanol, inowanzonzi isopropanol kana 2-propanol kana doro rekunze, ine kemikari formula C3H8O kana C3H7OH, isanganiswa isina ruvara, inopisa uye yakasimba inonhuwa, inonyanya kushandiswa sechinhu chinonyungudutsa mukuchengetedza, disinfectants uye detergents.Iri rudzi rwedoro rinoshandiswa zvakare sechinhu chikuru chedoro rekunze uye sanitizer yemaoko.Iyo inoputika uye inosiya manzwiro anotonhorera kana yashandiswa zvakananga paganda risina chinhu.Kunyange zvazvo yakachengeteka kushandiswa paganda, isopropanol, kusiyana ne ethanol, haina kuchengeteka nokuti ine chepfu uye inogona kukonzera kukanganisa kwenhengo kana ikaputirwa kana kumedzwa.
