Iimeko xa ifama kufuneka isebenzise utywala, ayinqabi kakhulu. Nangona kunjalo, musa ukulibala ukuba izicotha ezininzi zinetyhefu emntwini. Owona mzekelo ubalulekileyo wokugcotha okwahlukileyo kwaye kwangaxeshanye onjalo i-methyl efanayo ye-methyl kunye ne-Ethyl itywala. Eyona ngxaki iphambili kukuba impazamo yokhetho inokujika ibe yimiphumo emihle kakhulu, ukulahleka kobomi bomntu. Ukuze le nto le yenzeki, kubalulekile ukwazi ukuba ungakwazi ukwahlula-hlula oku kuqhelekileyo kwemichiza.
Phosa imibala eyahlukeneyo.
Ukwahlula i-methanol evela e-Ethanol kwiliso akunakwenzeka. Zombini ulwelo lubonakala lufana ngokuchanekileyo - lungabonakali njengamanzi, lube noxinano olufanayo kunye ne-faisticy ivumba. Kubalulekile ukukhumbula ukuba isiselo se-methyl (sinefomula ye-Ch3 yimveliso eyingozi ukuba kwimeko yokusetyenziswa ngumntu ngempazamo kuya kukhokelela ekufeni kwakhe. Ukuba kwade nokufa akuyi kuza, kuxhomekeka kwidosi, umntu unokwenzakala, ukuba ngumntu okhubazekileyo.
Nceda isoda.
Inyaniso enomdla: I-Methanol yafunyanwa kuqala ngusosayensi lwesiNgesi uRobert Boylel ngo-1661 ngelixa usebenza neemveliso zokudibanisa iinkuni ezomileyo. Kwangelo xesha, kwifom yalo enyulu, i-methyl itywala yafunyanwa kuphela ngo-1834 ngoochwephesha baseShean-Batiste Dumas nase-Eugene Peligo. Ifomula yezi ntombazana yafunyanwa.
Ungajonga iitapile.
I-ethanol okanye i-ithyl yotywala (ine-c2h5oh5) ityhefu ityhefu kwaye ifanelekile ukubandakanya kwishishini lokutya (kulo rhoqo). Kubalulekile ukukhumbula kwaye uqonde ukuba i-ethanol ayikaze isetyenziswe kwifom yayo ecocekileyo. Ukuba ungawutyesheli lo mthetho, unokukhetha kwakhona kwaye ufumanekekala (kuqala kuko konke ukuvutha okungaphezulu kwe-mucous membrane).
Ungalibali ukuba ukongeza kwi-eshanol yokutya kukho nezonyango.
Ungaziqonda njani, phi kwaye ziphi iziselo? Okokuqala, i-alcolols yahlulahlulwe yivumba labo. Nangona kunjalo, ndimisele ukuba yeyiphi na yazo, umntu ngaphandle kwemfundo yemichiza akazukukwazi. Ukongeza, ukutshata okutshatshewa kweekhemikhali zekhemikhali kukuphazamiseka ngqo kokhuseleko. Ungafumana impumlo kunye nomqala tshise, ukuya kufe.
Ke ngoko, sabela ezona ndlela zintathu ziphambili zokuhlolwa kwe-hoody-laboratring:
Into ephambili xa ujonge, ungavutheli nto.
Vavanya umlilo -Sithatha i-Wtasts ezimbini, sibahlambe kwii-alcohols kwaye sivutha umlilo. I-ethanol iya kutshisa iblowu. I-methanol iya kutshisa eluhlaza.
Uvavanyo lweSoda -Chix umxube kancinci kwisitya esahlukileyo kwaye wongeza iSoda apho. Emva koko, jonga impendulo. Ukuba isoda siyabona kwaye siwele ezantsi - le i-ethanol. Ukuba iSoda ichithwe- le yi-methanol.
Ukuvavanya i-potato -Sicoca kwaye sihlambe iitapile, usike kwiihafu ezimbini. Iitapile zifakwa kwizikhongozeli ezahlukeneyo kwaye zizikhukula ngamalahle enxila. Kwimeko enjalo, iziqwenga zihlala ngentsimbi yesi-5. Emva koko, jonga impendulo. Elo bhatata, eya kuba yipinki, isixelela ukuba ulele e-Ethanol.
