I-acetonelulwelo olungenambala, oluguquguqukayo oluxubana namanzi kwaye lunyibilika kwizinyibilikisi ezininzi eziphilayo.Yinto esetyenziswa ngokubanzi kwi-solvent ye-industrial kunye noluhlu olubanzi lwezicelo kwimichiza, i-pharmaceutical, i-cosmetics, kunye namanye amashishini.Kweli nqaku, siza kuphonononga indlela yokwenza i-acetone kwilebhu ngokusebenzisa isikhokelo senyathelo ngenyathelo kunye nokusetyenziswa kwayo.

Ukwenza iAcetone kwiLab

Kukho iindlela ezininzi zokwenza i-acetone kwilabhu.Enye yeendlela eziqhelekileyo ibandakanya i-acetone oxidation usebenzisa i-manganese dioxide njenge-oxidant.Nantsi inyathelo ngenyathelo isikhokelo sokwenza i-acetone kwilebhu:

Inyathelo 1: Qokelela imathiriyeli kunye nezixhobo ezifunekayo: Uya kufuna imanganese diokside, iacetone, icondenser, i-mantle yokufudumeza, imagnethi eshukumayo, iflaski enentamo ezintathu, kunye nezinto zeglasi ezifanele ukusetyenziswa elebhu.

Inyathelo 2: Yongeza iigram ezimbalwa zemanganese diokside kwiflaski enentamo ezintathu kwaye uyifudumeze kwimpahla yokufudumeza ide inyibilike.

Inyathelo lesi-3: Yongeza amathontsi ambalwa e-acetone kwiflask kwaye uvuselele kakuhle.Qaphela ukuba i-reaction i-exothermic, ngoko qaphela ukuba ungayitshisi kakhulu.

Inyathelo lesi-4: Qhubeka ushukumisa umxube malunga nemizuzu engama-30 okanye de kuphele ukuvela kwerhasi.Oku kubonisa ukuba impendulo iphelele.

Inyathelo lesi-5: Pholisa umxube kwiqondo lobushushu begumbi kwaye uwudlulisele kwifuneli eyahlulayo.Ukwahlula isigaba sezinto eziphilayo kwisigaba samanzi.

Inyathelo lesi-6: Yomisa i-organic phase usebenzisa i-magnesium sulfate kwaye uyihluze nge-vacuum filter yendlela emfutshane ukususa nakuphi na ukungcola.

Inyathelo lesi-7: Galela i-acetone usebenzisa useto olulula lwelabhoratri yedistillation.Qokelela amaqhezu ahambelana neqondo lokubila leacetone (malunga nama-56°C) kwaye uziqokelele kwisingxobo esifanelekileyo.

Inyathelo 8: Vavanya ukucoceka kwe-acetone eqokelelweyo usebenzisa iimvavanyo zemichiza kunye nohlalutyo lwe-spectrographic.Ukuba ukucoceka kuyanelisa, wenze ngempumelelo i-acetone kwilebhu.

Ukusetyenziswa okunokwenzeka kweAcetone eyenziwe ngeLab

I-acetone eyenziwe ilebhu ingasetyenziselwa iinjongo ezahlukeneyo.Nazi ezinye izinto ezinokuthi zisetyenziswe:
