Boiling point yen-Butanol: ruzivo uye zvinofurira zvinhu
n-Butanol, inozivikanwawo se 1-butanol, inowanzoshandiswa mumakemikari, pendi uye maindasitiri emishonga. Iyo yekubikira ndiyo inonyanya kukosha parameter yezvinhu zvemuviri zven-Butanol, izvo zvisingangokanganisa kuchengetedza uye kushandiswa kwen-Butanol, asiwo kushandiswa kwayo sechinhu chinonyungudutsa kana chepakati mumakemikari maitiro. Mupepa rino, tichakurukura zvakadzama kukosha kweiyo n-butanol yekubikira nzvimbo uye zvinofurira zviri shure kwayo.
Basic data pane yekubikira poindi ye n-butanol
Iko kuvira kwe n-butanol i117.7 ° C pamhepo yemhepo. Tembiricha iyi inoratidza kuti n-butanol inoshanduka kubva pamvura ichienda kune gasi kana ichipisa kusvika kune iyi tembiricha. n-Butanol is organic solvent ine medium boiling point, iyo yakakwirira kudarika yediki molecule doro senge methanol uye ethanol, asi yakaderera pane yezvinwiwa zvinodhaka zvine cheni refu kabhoni sepentanol. Kukosha uku kwakakosha zvikuru mukushanda kwemaindasitiri, kunyanya kana zvasvika kumatanho akadai sedistillation, kupatsanurwa uye kudzoreredza kudzoreredza, uko ukoshi chaihwo hwenzvimbo yekubikira hunotaridza kushandiswa kwesimba uye kusarudzwa kwemaitiro.
Zvinhu zvinokanganisa nzvimbo yekubikira ye n-butanol
Molecular structure
Iyo yekubikira poindi yen-butanol yakanyatso hukama neiyo molecular chimiro. n-Butanol mutsara wakazara doro ne molecular formula C₄H₉OH. n-Butanol ine nzvimbo yepamusoro yekubikira nekuda kwemasimba akasimba epakati pemamolecular (eg, van der Waals masimba uye hydrogen bonding) pakati pemitsetse mamorekuru kana ichienzaniswa neyakavharwa kana cyclic zvimiro. Kuvapo kweboka re hydroxyl (-OH) mu n-butanol molecule, boka rinoshanda re polar rinogona kuumba hydrogen bond nemamwe mamorekuru, rinowedzera kukwidza kuvira kwayo.

Atmospheric Pressure Shanduko
Iyo yekubikira poindi yen-butanol inobatwawo nemhepo yemhepo. Iyo n-butanol inovira ye117.7 ° C inoreva nzvimbo yekuvira pachiyero chemhepo yemhepo (101.3 kPa). Pasi pepasi pemamiriro ekunze ekumanikidza, senge munzvimbo yevacuum distillation, nzvimbo yekubikira yen-butanol ichaderera. Semuenzaniso, munzvimbo ine semi-vacuum inogona kufashaira patembiricha iri pasi pe100°C. Naizvozvo, iyo distillation uye yekuparadzanisa maitiro e-n-butanol inogona kunyatsodzorwa nekugadzirisa ambient pressure mukugadzirwa kwemaindasitiri.

Kuchena uye zvinhu zviripo
Iyo yekubikira yen-butanol inogona zvakare kukanganiswa nekuchena. High kuchena n-butanol ine kuvira kwakadzikama kwe117.7°C. Zvisinei, kana tsvina iripo mu-n-butanol, izvi zvinogona kushandura nzvimbo yekubikira chaiyo ye n-butanol kuburikidza neazeotropic madhara kana kumwe kupindirana kwefizikiki. Semuenzaniso, apo n-butanol inosanganiswa nemvura kana zvimwe zvinonyungudutsa zvehupenyu, chiitiko che azeotropy chinogona kuita kuti nzvimbo yekubikira yemusanganiswa ive yakaderera pane yakachena n-butanol. Naizvozvo, ruzivo rwekuumbwa uye hunhu hwemusanganiswa hwakakosha pakudzora kwakaringana kwekubikira.

Zvishandiso zve n-butanol yekubikira poindi muindasitiri
Muindasitiri yemakemikari, kunzwisisa uye kutonga kwekubikira kwen-butanol kwakakosha kune zvinoshanda. Semuenzaniso, mukugadzira maitiro apo n-butanol inoda kuparadzaniswa kubva kune zvimwe zvikamu ne distillation, tembiricha inofanira kunyatsodzorwa kuti ive nechokwadi chekuparadzana kwakanaka. Mune solvent recovery systems, iyo inofashaira yen-butanol inotarisawo dhizaini yemidziyo yekudzoreredza uye kugona kwesimba rekushandisa. Iyo ine mwero yekubikira poindi ye-n-butanol yakatungamira mukushandiswa kwayo mune yakawanda solvent uye kemikari maitiro.
Kunzwisisa kuvira kwen-butanol kwakakosha pakushandiswa kwayo mumakemikari ekushandisa. Ruzivo rwenzvimbo yekubikira yen-butanol inopa hwaro hwakasimba hwekugadzirisa dhizaini uye kuvandudzwa kwechigadzirwa, zvese mukutsvagisa marabhoritari uye mukugadzirwa kwemaindasitiri.
