Acetone boiling point analysis uye zvinofurira zvinhu
Acetone, inozivikanwawo se dimethyl ketone, yakakosha organic solvent ine huwandu hwakawanda hwekushandisa muindasitiri yemakemikari. Kunzwisisa nzvimbo yekubikira yeacetone kwakakosha pakugadzira uye kushanda kwemakemikari maitiro. Mune ino bepa, isu tichaongorora iyo inofashaira poindi yeacetone zvakadzama uye kukurukura yayo yakakosha zvimiro uye zvinofurira zvinhu.
Basic Properties yeAcetone
Acetone, ine kemikari formula C₃H₆O uye molecular huremu hwe 58.08 g/mol, imvura isina ruvara, inoputika uye inonaka uye inonhuwirira. Nekuda kwekunakisisa kwayo solvency, acetone inoshandiswa zvakanyanya mumadhizaini, zvinonyungudutsa, zvekupotera, zvemishonga uye maindasitiri epurasitiki. Mumashandisirwo aya, ruzivo rwechimiro chechimiro cheacetone, senge yekubikira poindi, yakakosha kudzora maparamendi.
Chii chinonzi boiling point yeacetone?
Iko kuvira kweacetone kunowanzo kunyorwa se 56 ° C (inenge 329 K) pane yakajairwa atmospheric pressure (101.3 kPa). Tembiricha iyi ndiyo tembiricha apo acetone inoshanduka kubva pamvura kuenda kune gasi. Iyo yakadzikira yekubikira poindi yeacetone kana ichienzaniswa nemamwe organic zvinonyungudutsa zvinoreva kuti inonyungudika pakupisa kwekamuri. Ichi chivakwa chinobvumira acetone kubuda nekukurumidza mune akawanda maindasitiri maapplication, kufambisa nekukurumidza kuomesa uye kuchenesa maitiro.
Zvinhu zvinokanganisa kuvira kweacetone
Iyo yekubikira yeacetone haina kumira uye inobatwa nehuwandu hwezvinhu. Zvinhu zvinonyanya kukosha zvinosanganisira kumanikidzwa kwekunze, kusvibiswa kwemukati uye chikamu chemusanganiswa wekunyungudutsa.

Mhedzisiro yekudzvinyirirwa kwekunze: Pakumanikidzwa kwakadzika, nzvimbo yekuvira yeacetone inoderera. Munguva yevacuum distillation, kudzikisa kudzvanywa kunobvumira acetone kuvira pane yakaderera tembiricha, nekudaro kuderedza kurasikirwa kwekupisa uye kushandiswa kwesimba. Naizvozvo, kudzora kudzvanywa inzira inoshanda yekudzora nzvimbo yekuvira yeacetone panguva yeindasitiri distillation.

Mhedzisiro yekusachena: kuvapo kwetsvina muacetone kunokanganisa kuvira kwayo. Iyo yakakwirira kuchena, iyo inoswedera pedyo iyo nzvimbo yekubikira iri kune yakajairika kukosha; nepo misanganiswa ine zvimwe zvinhu zvinoputika zvinogona kuguma nekushanduka kwenzvimbo yekuvira. Pakugadzirwa kwemakemikari akanaka, zvakakosha kudzora kuchena kweacetone kuve nechokwadi chekugadzikana kwayo pane tembiricha yakatarwa.

Mhedzisiro yemusanganiswa wekunyungudutsa: Kana acetone yakasanganiswa nezvimwe zvinonyungudutsa, nzvimbo yekuvira kwayo inogona kuchinja. Ichi chiitiko chinozivikanwa se azeotropy. Mukuita, iyo azeotropic point yeacetone nemamwe masolvents inoda kutariswa kwakakosha sezvo inogona kukanganisa kushanda kweiyo nzira yekuparadzanisa.

Kukosha kweAcetone Boiling Point
Kunzwisisa uye kudzora nzvimbo yekubikira yeacetone kwakakosha kunoshanda mukugadzirwa kwemaindasitiri. Mune akawanda emakemikari maitiro, senge solvent kudzoreredza, distillation kupatsanurwa uye maitiro ekuita, ruzivo rwakakwana rwekubikira kweacetone inogona kubatsira kukwirisa maparamita ekuita, kuvandudza kugadzirwa kwekugadzira uye kuve nechokwadi chemhando yechigadzirwa.
Iyo yekubikira poindi yeacetone ndiyo yakakosha yemuviri parameter muindasitiri yemakemikari. Kungave mukushandiswa kwesolvent, kemikari kuita kana kupatsanurwa kwe distillation, kunzwisisa nzvimbo yekubikira yeacetone uye zvakasiyana siyana zvinoikanganisa hwaro hwakakosha hwekuve nechokwadi chekugadzirwa kwakatsetseka.
