Indawo yokubila ye-N-butanol: iinkcukacha kunye nefuthe lezinto zokuphembelela
I-N-B-butanol, ekwabizwa ngokuba yi-1-butanol, isetyenziswa ngokubanzi kwicandelo lemichiza, ipeyinti kunye namashishini amayeza. Indawo yokubila yiparamitha ebaluleke kakhulu ye-N-B-butanol, engachaphazeli i-Stored kunye nokusetyenziswa kwe-N-Bheanol, kodwa inesicelo sayo njengeenkqubo zemichiza. Kweli phepha, siza kuthetha ngokweenkcukacha ixabiso elithile lendawo yokubila i-N-B-butanol yokubila kunye nezinto eziphambene ngasemva kwawo.
Idatha esisiseko kwindawo yokubila ye-N-butanol
Indawo yokubila ye-N-Butanol yi-117.7 ° C kwi-themospic cinezela. Eliqondo lobushushu libonisa ukuba i-N-Butanol iya kutshintsha ukusuka kulwelo ukuya kwi-Gaseous State xa ifudumele kolu qondo. I-N-B-butanol sisinyibilikisi sezinto eziphilayo, esingaphezulu kokucola iimolethisi ezifana ne-methanol kunye ne-ethanol, kodwa ziphantsi kune-Pentanol imixokelelwane efana nePentanol. Eli xabiso libaluleke kakhulu kwimisebenzi esebenzayo yemizi-mveliso, ngakumbi xa kufikwa kwiinkqubo ezifana nokuphambana, ukwahlukana kunye nokubuyiswa kwesinyithi, apho ixabiso lokufumana inqaku lokubila libonisa ukusetyenziswa kwamandla kunye nokukhethwa kwenkqubo.
Izinto ezichaphazela indawo yokubila ye-N-butanol
Ulwakhiwo lweMolekyuli
Indawo yokubila ye-N-butanol ihambelana ngokusondeleyo nesakhiwo sayo semolekyuli. I-N-B-butanol ngumgca ogcwele utywala ngefomula yemolekyuli c₄hhoh. I-N-B-butanol inendawo ebilayo ebilayo ngenxa yemikhosi engathandekiyo ye-Intermolecular (umz. Ubukho beqela le-hydroxyl (-d) kwi-N-Bianol Molecule, iqela elisebenzayo elinokwenza iimolethi ze-hydrogen kunye nezinye iimolekyuli, ziphinda ziphakame ngakumbi indawo yayo yokubila.

UTSHINTSHO LWE-ATMOSFERIC
Indawo yokubila ye-N-Butanol ikwachaphazeleka yingcinezelo ye-themospheric. Inqaku lokubila i-N-B-B-Bhananol Liling ye-117.7 ° C ibhekisele kwindawo yokubila kwi-themospic the pumeric uxinzelelo (i-101.3 kpa). Ngaphantsi kweemeko zoxinzelelo ezisezantsi zemotosmic, ezinjengendawo yokuhlangana engaphakathi, indawo yokubila ye-N-Butanol iya kuncipha. Umzekelo, kwimeko ye-semi-vacuum enokubilisa amaqondo obushushu angaphantsi kwe-100 ° C. Ke ngoko, ukunqongophala kunye nenkqubo yokwahlukanisa i-N-Butanol kunokulawulwa ngokufezekileyo ngokuhlengahlengisa uxinzelelo lwengcinezelo kwimveliso yemizi-mveliso.

Ukucoceka kunye nezinto ezikhoyo
Indawo yokubila ye-N-Butanol inokuchaphazeleka kukucoceka. Ucoceko oluphezulu n-butanol unendawo yokubila ebilayo ye-117.7 ° C. Nangona kunjalo, ukuba ukungcola kubekhona kwi-N-Butanol, ezi zinokutshintsha indawo yokuthintela i-N-butanol ngefuthe le-azeotropic okanye ezinye iindlela zomsebenzi. Umzekelo, xa i-N-B-butanol ixutywe namanzi okanye ezinye izinto eziphilayo, i-hletomen ye-azeoyotropy inokubangela indawo yokubila yomxube ukuba iphantsi kuneso si-chaugh n-bhananol. Ke ngoko, ulwazi malunga nokuqulunqwa kunye nohlobo lomxube kubalulekile kulawulo oluchanekileyo lokubilisa.

Izicelo zendawo yokubila i-N-B-butanol Boilayong kwishishini
Kumzi-mveliso wekhemikhali, ukuqonda nokulawula indawo yokubila ye-N-Butanol kubalulekile ngeenjongo ezisebenzayo. Umzekelo, kwiinkqubo zemveliso apho i-N-B-butanol kufuneka yahlulwe kwamanye amacandelo ngokuthi, iqondo lobushushu kufuneka lilawulwe ngokuchanekileyo ukuqinisekisa ukwahlulwa okufanelekileyo. Kwinkqubo yokubuyisela kwimeko yesilivere, indawo yokubila ye-N-Butanol ikwamisela uyilo lwezixhobo zokubuyisela kunye nokusebenza kakuhle kokusetyenziswa kwamandla. Indawo yokubila ngokumodareyitha ye-N-Butanol ikhokelele ekusebenziseni kwayo kwizinyithi ezininzi kunye nokuphendula kwekhemikhali.
Ukuqonda indawo yokubila kwe-N-butanol kubalulekile ekusetyenzisweni kwalo kwizicelo zemichiza. Ulwazi malunga nendawo ebilayo ye-N-Butanol ibonelela ngesiseko senkqubo yoyilo kunye nophuculo lwemveliso, zombini kuphando lwelebhu nakwimveliso yemizi-mveliso.
