Utshwala Boiling Point

Ngezinye ingcindezi evamile asemkhathini, utshwala lokushisa 78,3 ° C (i-ethanol) abilayo. Kumele kukhunjulwe ukuthi izinga lokushisa alushintshi njalo, ngisho nalapho okokufaka ukushisa Kwenziwa njalo. Lesi sici yenqubo ngenxa yokuthi ukuthi ukuguqulwa kwezinto uketshezi umusi kwenzeka futhi uma ukufinyelela lokushisa ethile esinqunyiwe ngoba into ebalulekile - ukushisa yokuhwamuka.

Njengoba kwanda isisindo yamangqamuzana izinga lokushisa utshwala ukubila luyanda, isilinganiso ine ifomu ephambene ngoba alcohols emi eduze ilandelana, kusukela ETHYL. Ngokwezinombolo, ukubaluleka kwalo kunalelo efanayo Inkomba y ethers noma hydrocarbon ukuba babe isisindo yamangqamuzana efanayo. Ngakho, lo mkhuba ubabonisa phezu nemikhiqizo yalezi izinto. Le mpahla kungenxa yokuba khona alcohols yokuzihlanganisa yamangqamuzana ngenxa yokuba khona lichaza ekwakheni amaqembu hydroxyl.

Ikakhulu utshwala abilayo lokushisa kunqunywa yayo isakhiwo sazo sekhemikhali. Lapha kukhona umthetho jikelele: ingxenye enkulu utshwala lihlukile ezakhiwe classic, ngakho izinga lokushisa ukubila ingaphansi.

Lapho eqhathanisa ukubila amaphuzu ezahlukene alcohols nge abilayo amaphuzu etholakala therefrom ethers Kutholwe indlela eyingqayizivele engafaniswa - alcohols ifa cishe normal ngobukhulu, kakhulu okushisa aphezulu.

Okuningi esisemthethweni ukubila lokushisa luncike amagugu ubukhulu bale isisindo yamangqamuzana we utshwala ethile. Ngokwesibonelo, abilayo ka ETHYL utshwala kuyinto 78,15 ° C nge isisindo yamangqamuzana 46,069. e. m. Ngesikhathi esifanayo, izinkomba ezifanayo ube methyl kukhona ngokulandelana 64,7 ° C futhi 32,04 a. e. m. isibonelo esifanayo kuyisici sobuntu zonke alcohols.

Hydrolysis utshwala ngokuvamile eyenziwa uma ifinyelela emvuthwandaba, lesi isikhathi sasivumela eside ngenqubo, ozobakhona cishe eziyishumi amahora.

ipharamitha ezinjengokusebenzisa kabi uphuzo oludakayo omlilo lokushisa kakhulu inquma nobubanzi ukusetshenziswa kwalezi compounds e umkhakha kanye nasemakhaya. Nokho, lapho kufanele sithathwe njengehlelo uhlobo aspect amandla omlilo. Amandla omlilo ukusabela zihlukaniswa ngamaqembu amane. Uhlobo lokuqala lihlanganisa zonke izinqubo omlilo ezenzeka ngenxa angenayo i-oksijini eziqukethwe emoyeni kuma. Kuhlanganisa uwoyela omlilo ukuphendula, kanye notshwala. Le nqubo uwukubonakaliswa le ndlela elandelayo: C2H5OH + 3O2 + 11,3 N2 = 2CO2 + 3H2O + 11,3N2.

Ngokuhlola ifomula ngenhla, kufanele kuqondwe ukuthi it is hhayi kubonakala umqondo ogcwele kugucuka chemical ezenzeka kanye izinto iqhaza ekusabeleni amandla omlilo. Ifomula yenziwa ngenxa yezizathu ukuthi umoya siqukethe kuphela oksijini nitrogen sithathwa zero khona therein yamagesi inert.

Udaba phambi kwethu kukho - emvuthwandaba utshwala - kudala ukusetshenziswa amaningi. Le ukusetshenziswa ukuba iningi like ukusetshenziswa alcohols njengoba izinto ezivuthayo futhi impahla akha izinhlobo ezahlukene motor fuel ezaziwayo. Ngenxa yale njongo, okuvame ukusetshenziswa methanol, Ethanol futhi butanol, okuyinto akhiqizwa emhlabeni wonke ngezinga ezimbonini. amavolumu enjalo ukukhiqizwa ngenxa ukutholakala kwayo kwezokuthengiselana futhi conjuncture eliphezulu emakethe, ngaphezu kwalokho, ukukhiqizwa kwezinye izimo, asetshenziswa njengoba izinkomba kanye namazinga okuhlola izinga kwezobuchwepheshe isimo. izindawo ngamunye kwezobuchwep kuyizinto ukukhiqizwa biodiesel, izihlanzi, upende neminye imikhiqizo eminingi, okuyinto akunakwenzeka ukuba uhlu kwelinye sihloko iDemo.
