Isopropanolkunye ne-ethanol zialkoholi ezimbini ezidumileyo ezinezicelo ezininzi kumashishini ahlukeneyo.Nangona kunjalo, iimpawu zabo kunye nokusetyenziswa kwazo kwahluka kakhulu.Kule nqaku, siya kuthelekisa kwaye sithelekise i-isopropanol kunye ne-ethanol ukumisela ukuba yintoni "engcono".Siza kuqwalasela izinto ezifana nemveliso, ubuthi, ukunyibilika, ukutsha, kunye nokunye.
Ukuqala, makhe sijonge iindlela zokuvelisa ezi tywala zimbini.I-Ethanol idla ngokuveliswa ngokubiliswa kweswekile ethathwe kwi-biomass, iyenza ibe sisixhobo esinokuhlaziywa.Ngakolunye uhlangothi, i-isopropanol yenziwe kwipropylene, i-petrochemical derivative.Oku kuthetha ukuba i-ethanol ine-advanteji malunga nokuba yenye indlela ezinzileyo.
Ngoku makhe sihlolisise ubutyhefu babo.I-Isopropanol inetyhefu ngakumbi kune-ethanol.Iyaguquguquka kakhulu kwaye inendawo yokudanyaza esezantsi, nto leyo eyenza ibe yingozi yomlilo eyingozi.Ukongeza, ukungeniswa kwe-isopropanol kunokubangela iziphumo ezibi zempilo, kubandakanya ukonakala kwesibindi kunye nezintso, ukudakumba kwenkqubo ye-nervous, kunye nokufa kwiimeko ezinzima.Ke ngoko, xa kufikwa kwityhefu, i-ethanol ngokucacileyo yeyona ndlela ikhuselekileyo.
Ukuqhubela phambili kwi-solubility, sifumanisa ukuba i-ethanol inokunyibilika okuphezulu emanzini xa kuthelekiswa ne-isopropanol.Le propati yenza ukuba i-ethanol ifaneleke ngakumbi ukusetyenziswa kwizicelo ezahlukeneyo ezifana nezibulali ntsholongwane, izinyibilikisi, nezithambiso.I-Isopropanol, kwelinye icala, ine-solubility ephantsi emanzini kodwa ixubene ngakumbi kunye nezinyibilikisi eziphilayo.Olu phawu luyenza ilungele ukusetyenziswa kwiipeyinti, izinto zokuncamathelisa, kunye neengubo.
Okokugqibela, makhe siqwalasele ukutsha.Zombini i-alcohols zivutha kakhulu, kodwa ukutsha kwazo kuxhomekeke ekugxininiseni kunye nobukho bemithombo yokutshisa.I-Ethanol ine-flash point ephantsi kunye ne-auto-ignition degrees kune-isopropanol, okwenza kube lula ukubamba umlilo phantsi kweemeko ezithile.Nangona kunjalo, zombini kufuneka ziphathwe ngononophelo olukhulu xa zisetyenziswa.
Ukuqukumbela, utywala "obungcono" phakathi kwe-isopropanol kunye ne-ethanol kuxhomekeke kwisicelo esithile kunye neempawu ezifunwayo.I-Ethanol ibalasele njengeyona ndlela ikhethwayo ngokubhekiselele kuzinzo kunye nokhuseleko.Ubutyhefu bayo obuphantsi, ukunyibilika okuphezulu emanzini, kunye nomthombo ohlaziyekayo kuyenza ilungele uluhlu olubanzi lokusetyenziswa ukusuka kwizibulali ntsholongwane ukuya kumafutha.Nangona kunjalo, kwizicelo ezithile zoshishino apho iikhemikhali zayo zifunwa khona, i-isopropanol ingaba yinto engcono kakhulu.Nangona kunjalo, kubalulekile ukuphatha zombini ii-alcohols ngononophelo olukhulu njengoko zivutha kakhulu kwaye zinokuba yingozi xa ziphathwa kakubi.
