Boiling point kuongororwa kweacetic acid: tembiricha, zvinofurira zvinhu uye mashandisirwo
Acetic acid (kemikari formula CH₃COOH), inozivikanwawo seacetic acid, is organic acid inoshandiswa zvakanyanya mumaindasitiri emakemikari, ezvekudya uye emishonga. Iwo emuviri zvimiro zveacetic acid, kunyanya kubikira kwayo, kwakakosha pakugadzira uye mashandisirwo muindasitiri yemakemikari. Muchikamu chino, tichaongorora nzvimbo yekuvira yeacetic acid zvakadzama, tokurukura zvinofurira zvinhu uye kukosha kwayo mumamiriro akasiyana ekushandisa.
Mhedziso yepamusoro yenzvimbo yekubikira yeacetic acid
Iko kuvira kweacetic acid i117.9 ° C (244.2 ° F), iyo inopimwa pachiyero chemhepo yemhepo (1 atmosphere, 101.3 kPa). Patembiricha iyi, acetic acid inoshanduka kubva pamvura ichienda kugasi, muitiro unova danho rinokosha mumakemikoro akawanda. Acetic acid ine nzvimbo yakanyanyisa kuvira kana ichienzaniswa nemamwe macompounds akajairika, ayo anonyanya kuverengerwa kuvepo kwehydrogen bond pakati pemamorekuru ayo.
Zvinhu zvinokanganisa nzvimbo yekubikira yeacetic acid
Kunyange zvazvo chiyero chekufashaira kweacetic acid chiri 117.9 ° C, mukuita tembiricha iyi inobatwa nehuwandu hwezvinhu. Dzvinyiriro ine mhedzisiro yakakosha pairi kuvira. Pakudzvinyirirwa kwakaderera (semuenzaniso, vacuum mamiriro), nzvimbo yekubikira yeacetic acid inoderera zvakanyanya, nepo munzvimbo dzakanyanya-kudzvanywa, nzvimbo yekubikira inowedzera. Naizvozvo, panguva yeindasitiri distillation, kudzora kudzvanywa kweiyo system kunogona kunyatso kudzora kufashaira uye kupatsanura kugona kweacetic acid.
Kusachena mumushonga kunogonawo kuva nemigumisiro pairi kuvira kweacetic acid. Kunyanya kana acetic acid ikaita musanganiswa nemamwe macompound, painofashaira inogona kutsauka kubva pahunhu hwakajairika. Semuenzaniso, mune aqueous solutions, iyo inofashaira yeacetic acid inogona kuderedzwa nekuda kweazeotropic phenomena. Kunzwisisa uye kudzora zvinhu izvi kwakakosha kukwenenzvera kugadzirwa kwemakemikari.
Zvishandiso zveAcetic Acid Boiling Points muIndasitiri
Iyo yekubikira yeacetic acid haingori yakakosha parameter kune yayo yemuviri zvimiro, zvakare yakakosha mukupesvedzera mashandisirwo ayo mune akati wandei maindasitiri maitiro. Chishandiso chinowanzoitwa ndiko kudistillation uye kucheneswa kweacetic acid. Mukugadzirwa kwemakemikari, kunyatso kudzora kwenzvimbo yekubikira inhanho yakakosha pakuwana kuchena kwakakwirira acetic acid. Mukugadzirwa kweacetate uye acetate esters, kudzorwa kwenzvimbo yekubikira yeacetic acid kune zvakare kukanganisa kwakananga pamhando yechigadzirwa uye kugadzirwa.
Iyo yekubikira poindi yeacetic acid ine zvakare yakakosha maapplication mukutarisa kwezvakatipoteredza uye maitiro ekurapa. Kurapa kwemvura yakasviba kana gasi remarara rine acetic acid inogona kuwanikwa nekupisa acetic acid kuburikidza nekudziya. Naizvozvo, kugona kuvira kweacetic acid uye mutemo wayo wekuchinja kwakakosha pakugadzira nzira yekurapa inoshanda.
Summary
Iyo yekubikira poindi yeacetic acid yakakosha yemuviri parameter ine yakafara application kukosha muindasitiri yemakemikari. Kunzwisisa uye kugona zvinhu zvinopesvedzera zvekubikira kweacetic acid, senge kudzvanywa uye kusachena zvirimo, zvinogona kubatsira mainjiniya uye matekinoroji kukwidziridza maitiro ekugadzira uye kugadzirisa mhando yechigadzirwa. Iko kushandiswa kwakawanda kweiyo yekubikira yeacetic acid muindasitiri inosimbisawo kukosha kwayo mukugadzira uye kuchengetedza kwezvakatipoteredza. Mukutsvagisa uye mashandisirwo anotevera, kuongororwa kwakadzama kweiyo acetic acid inofashaidzwa icharamba ichiunza budiriro yetekinoroji kuindasitiri yemakemikari.
