Ethyl Acetate Boiling Point Analysis: Basic Properties uye Influencing Factors
Ethyl Acetate (EA) yakajairika organic komboni ine dzakasiyana siyana dzekushandisa. Iyo inowanzoshandiswa sechinhu chinonyungudutsa, chinonhuwira uye chekuwedzera chikafu, uye inofarirwa nekusagadzikana kwayo uye kuchengeteka. Kunzwisisa zvakakosha zvivakwa uye zvinhu zvinokanganisa kuvira kwe ethyl acetate kwakakosha pakushandiswa kwayo mukugadzirwa kwemaindasitiri.
Basic Physical Properties yeEthyl Acetate
Ethyl acetate imvura isina ruvara ine fruity-sekunhuhwirira. Iine chimiro chemakemikari C₄H₈O₂ uye molecular uremu we88.11 g / mol. Nzvimbo yekubikira ye ethyl acetate ndeye 77.1 ° C (350.2 K) pamhepo yemhepo. Iyi poindi yekubikira inoita kuti zvive nyore kunyungudika patembiricha yekamuri, zvichiita kuti ive yakakodzera kushandiswa mumhando dzakasiyana dzemashandisirwo apo panodiwa kukurumidza kubuda.
Zvinhu zvinokanganisa nzvimbo yekubikira ye ethyl acetate

Mhedzisiro yekumanikidzwa kwekunze:

Iyo yekubikira poindi ye ethyl acetate ine hukama zvakanyanya ne ambient pressure. Pakudzvanywa kweatmospheric, panovira poindi ye ethyl acetate i77.1°C. Zvisinei, sezvo kudzvinyirirwa kunoderera, nzvimbo yekubikira inoderera maererano. Ichi chivako chakakosha mukushandiswa kwemaindasitiri, kunyanya muvacuum distillation, uko iyo yekubikira ye ethyl acetate inogona kuderedzwa zvakanyanya, zvichikanganisa kushanda kwekuparadzanisa uye kuchenesa maitiro.

Mhedzisiro yekuchena uye musanganiswa:

Kuchena kwe ethyl acetate zvakare kune mhedzisiro pairi kuvira. Kuchena kwepamusoro ethyl acetate ine nzvimbo yakagadzikana yekuvira iyo inogona kuchinja kana yakasanganiswa nemamwe masolvents kana makemikari. Chiitiko cheazeotropy chemisanganiswa muenzaniso wakajairika, umo zvimwe zvikamu zve ethyl acetate zvakasanganiswa nemvura zvinoumba musanganiswa neazeotropic point, zvichiita kuti musanganiswa uende pamwe chete pakupisa ikoko.

Intermolecular kusangana:

Intermolecular kudyidzana, senge hydrogen bonding kana van der Waals forces, haina kusimba mu ethyl acetate asi ichine mhedzisiro yakavanzika pakuvira kwayo. Nekuda kweiyo ester boka chimiro mu ethyl acetate molecule, iyo intermolecular van der Waals masimba mashoma, zvichikonzera yakaderera kuvira. Kusiyana neizvi, zvinhu zvine kudyidzana kwakasimba kweintermolecular kazhinji zvine mapoinzi epamusoro ekuvira.

Boiling point ye ethyl acetate muindasitiri

Ethyl acetate ine nzvimbo yekubikira ye77.1 ° C, pfuma yakakonzera kushandiswa kwayo kwakapararira sechinhu chinonyungudutsa muindasitiri yemakemikari, kunyanya mukugadzirwa kwependi, machira uye zvinonamira. Iyo yakaderera yekubikira poindi inobvumira ethyl acetate kubuda nekukurumidza, ichipa yakanaka solubility uye nyore kubata. Muindasitiri yemishonga, ethyl acetate inowanzoshandiswa pakubvisa uye kucheneswa kwemakemikari emuchadenga, sezvo nzvimbo yayo ine mwero yekubikira inobvumira kupatsanurwa kwakanaka kwezvinangwa zvinosanganiswa uye tsvina.

Kupfupikisa

Kunzwisisa kuvira kweiyo ethyl acetate uye zvinhu zvinoikurudzira zvakakosha pakugadzirwa uye kushandiswa muindasitiri yemakemikari. Nekunyatso kudzora ambient kumanikidza, kudzora kuchena kwezvinhu, uye kufunga nezve intermolecular kupindirana, kugona kwekushandisa ethyl acetate kunogona kunyatsogadziriswa. Icho chokwadi chekuti ethyl acetate ine nzvimbo yekubikira ye77.1 ° C inoita kuti ive yakakosha solvent uye yepakati mune akawanda maindasitiri ekushandisa.
