Boiling point yeEthylene Glycol uye kuongororwa kwayo kwemakemikari zvinhu
Muindasitiri yemakemikari, ethylene glycol (Ethylene Glycol) yakakosha kemikari mbishi zvinhu zvinoshandiswa zvakanyanya munzvimbo dzakasiyana siyana senge antifreeze uye resin kugadzirwa. Kunzwisisa physicochemical zvimiro zveEthylene Glycol, kunyanya kubikira kwayo, kwakakosha pakushandiswa kwayo muindasitiri. Muchinyorwa chino, iyo yekubikira poindi ye ethylene glycol uye yayo yakabatana inofurira zvinhu ichakurukurwa zvakadzama.
Basic Properties yeEthylene Glycol uye Iyo Boiling Point
Ethylene glycol imvura isina ruvara, isinganhuhwi, inonhuhwirira inotapira ine kemikari formula C₂H₆O₂. Se diol, ethylene glycol ine yakasimba hygroscopicity uye yakanaka solubility zvivakwa. Kuvira kwe ethylene glycol i197.3°C. Ukoshi uhwu, hukayerwa pamhepo yemuchadenga, hunoratidza kugadzikana kwechimiro chayo chemolecular uye kusimba kweiyo intermolecular hydrogen bond.
Zvinhu zvinokanganisa nzvimbo yekubikira uye kukosha kwayo kwemaindasitiri
Iyo yekubikira ye ethylene glycol inokonzerwa nehuwandu hwezvinhu. Hydrogen bonding muchimiro chemolecular ine mhedzisiro yakakosha pane yekuvira. Iyo ethylene glycol molecule ine mapoka maviri ehydroxyl (-OH), ayo akabatanidzwa nehydrogen bonds, zvichiita kuti intermolecular forces ye ethylene glycol yakasimba uye inotungamirira kune imwe nzvimbo yakanyanyisa kuvira. Huremu hwe ethylene glycol hunokanganisawo painofashaira, iine huremu hombe hwemamorekuru hunoda simba rakawanda rekubuda.
Mumaindasitiri ekushandisa, iyo yekubikira poindi ye ethylene glycol ine simba rakakura pakuita kwayo sechinhu chinonyungudutsa, chinotonhorera uye zvimwe zvigadzirwa. Semuenzaniso, nzvimbo yepamusoro yekubikira inoita kuti glycol igadzikane uye isanyanya kunyungudika pakupisa kwakanyanya, nokudaro kuve nechokwadi chekushanda kwayo mukutonhodza uye antifreeze.
Chengetedzo mukushandiswa kunoshanda
Paunenge uchishandisa ethylene glycol, kutarisisa kunoda kubhadharwa kune kupindirana kwekubikira kwayo nezvimwe zvinhu. Semuyenzaniso, mucomposites kana musanganiswa mhinduro, zvimwe zvinhu zvinogona kukanganisa boiling point ye ethylene glycol uye nekudaro hunhu hwekupedzisira hwechigadzirwa. Ruzivo rwekubikira poindi ye ethylene glycol inogona zvakare kubatsira kukwenenzvera maindasitiri ekugadzira maindasitiri, senge tembiricha yekudzora panguva ye distillation uye kuisa pfungwa.
Muchidimbu, kunzwisisa kwekubikira kwe ethylene glycol kwakakosha pakushandiswa kwayo kwemaindasitiri. Nekunzwisisa iyi pfuma yemuviri ye ethylene glycol, kuita kwayo mukugadzira nekushandisa kunogona kudzorwa zvirinani kuwedzera kunaka uye kugadzikana kwechigadzirwa.
