ʻO ka waiʻona kekahi o nā mea hoʻoheheʻe kemika maʻamau i ke ola o kēlā me kēia lā.He pūhui olaola me hoʻokahi pūʻulu hana hydroxyl (- OH) i hui pū ʻia me nā ʻātoma kalapona saturated.A laila, e like me ka helu o nā kalapona kalapona i hoʻopili ʻia i nā ʻāpana kalapona me nā pūʻulu hana hydroxyl, ua hoʻokaʻawale ʻia lākou i ka mua, ka lua a me ka tertiary.ʻEkolu ʻano mea hoʻoheheʻe kemika i hoʻohana mau ʻia i ke ola o kēlā me kēia lā.ʻo kahi laʻana;ʻO ka Methanol (ka waiʻona mua), ka ethanol (ka waiʻona mua) a me ka isopropanol (ka waiʻona lua).
Methanol
ʻO ka Methanol, i kapa ʻia hoʻi ka methanol ma nā inoa ʻē aʻe, he kemika me ke ʻano kemika CH3OH.He wai māmā, ʻoluʻolu, waihoʻoluʻu ʻole, ʻaʻa ʻole me kahi ʻala ʻawaʻawa kū hoʻokahi e like me ka ethanol.Hoʻohana pinepine ʻia ka Methanol e like me ka solvent, antifreeze, formaldehyde a me ka mea hoʻohui wahie i loko o ka hale hana.Eia kekahi, ma muli o kona hiki ʻole, hoʻohana ʻia ʻo ia e like me ka peni thinner.Eia nō naʻe, ʻo ka methanol kahi mea ʻona a me nā mea ʻawaʻawa.Inā inhaled a moni ʻia paha, e hoʻopilikia mau ʻia ka neurological a me ka make.
Ethanol
ʻO Ethanol, ʻike ʻia hoʻi he ethanol a i ʻole ka waiʻona palaoa, he mea hoʻohui, he waiʻona maʻalahi me ke ʻano kemika C2H5OH.He wai liʻiliʻi, ʻā, ʻaʻohe waihoʻoluʻu me kahi ʻala liʻiliʻi, ma ke ʻano o nā mea inu ʻona, e like me ka waina a i ʻole ka pia.Hiki ke ʻai pono ʻia ka Ethanol, akā e ʻoluʻolu e pale i ka ʻai nui ʻana ma muli o kona hoʻohui.Hoʻohana ʻia ʻo Ethanol ma ke ʻano he mea hoʻoheheʻe organik, kahi mea koʻikoʻi o ka wai a me nā huahana puaʻa, nā mea hoʻonaninani a me nā lāʻau synthetic.
ʻO ka waiʻona isopropyl
ʻO Isopropanol, ka mea maʻamau i kapa ʻia ʻo isopropanol a i ʻole 2-propanol a i ʻole ka waiʻona waho, me ke ʻano kemika C3H8O a i ʻole C3H7OH, he mea ʻala ʻole, lapalapa a ikaika hoʻi, hoʻohana nui ʻia ma ke ʻano he solvent i nā preservatives, disinfectants a me nā mea holoi.Hoʻohana ʻia kēia ʻano waiʻona ma ke ʻano he mea nui o ka waiʻona waho a me nā mea hoʻomaʻemaʻe lima.He palupalu a waiho ʻia kahi manaʻo ʻoluʻolu ke hoʻohana pololei ʻia ma ka ʻili ʻole.ʻOiai he palekana ka hoʻohana ʻana ma ka ʻili, ʻaʻole palekana ka isopropanol, ʻaʻole like me ka ethanol, no ka mea he mea ʻawaʻawa a hiki ke hōʻeha i ke kino inā e hanu a ʻai ʻia.
