Yintoni i-Ethanol?
Yintoni i-Ethanol? I-Ethanol, eyaziwa ngokuba yi-alcohol, yi-organic compound enefomyula yokwakha i-CH₃CH₂OH (okanye i-C₂H₅OH) kunye nefomyula ye-molecular i-C₂H₆O. Yeyona alcohol ixhaphakileyo ye-monohydric. Kwiqondo lobushushu begumbi kunye noxinzelelo, i-ethanol lulwelo oluvuthayo, oluguquguqukayo, olungenambala ...Funda ngokugqithisileyo -

Ibizwa ngokuba “lutywala&#...Funda ngokugqithisileyo -
Idlala yiphi indima i-ethanol kwishishini lokulungisa ukutya?
Ishishini Lokulungisa Ukutya Kwishishini lokutya, i-ethanol inezicelo ezininzi. Ngexesha lokwenziwa kwewayini, i-ethanol yenye yezona mveliso ziphambili zokubilisa. Iindidi ezahlukeneyo zewayini zinomxholo we-ethanol owahlukileyo: ibhiya idla ngokuba ne-3%–8% ye-ethanol, iwayini ijikeleze i-8%–15%, kunye neBaijiu (utywala baseTshayina)...Funda ngokugqithisileyo -
I-ethanol isetyenziswa njani kwipetroli?
Ukusetyenziswa kwepetroli I-Ethanol ngumthombo wamandla ococekileyo. Kwamanye amazwe nakwiindawo, yongezwa kwipetroli ukuvelisa ipetroli ye-ethanol—umzekelo, ukusetyenziswa kwayo kuxhaphake kakhulu eBrazil. Izithuthi ezisebenzisa ipetroli ye-ethanol zikhupha iigesi ezinobungozi ezimbalwa: xa kuthelekiswa nepetroli yendabuko, i-ethanol...Funda ngokugqithisileyo -
Zithini imisebenzi ye-Ethanol njengeSolvent?
I-Ethanol Njengesinyibilikisi I-Ethanol inokunyibilika okugqwesileyo. Kwishishini lamayeza, izinto ezininzi zamayeza azinyibiliki emanzini kodwa zinyibilika kakuhle kwi-ethanol. Umzekelo, ezinye izithambisi (umz., i-iodine tincture) zilungiswa ngokunyibilikisa i-iodine kwisisombululo esixutyiweyo se-ethanol namanzi. Njenge...Funda ngokugqithisileyo -
Zithini iziphumo ze-ethanol kwi-Disinfection kunye ne-Sterilization?
Ukubulala iintsholongwane kunye nokubulala iintsholongwane I-Ethanol sisibulali-ntsholongwane esisetyenziswa kakhulu. Ezibhedlele, isisombululo se-ethanol esingama-75% sisetyenziswa kakhulu ekubulaleni ulusu. Umzekelo, ngaphambi kokuba kufakwe inaliti okanye kutsalwe igazi, abahlengikazi basula ulusu ngee-cotton swabs ezifakwe kwi-75% ye-ethanol ukuze babulale iintsholongwane kunye neentsholongwane ngempumelelo...Funda ngokugqithisileyo -
