A isopropyl mowa, omwe amadziwikanso kuti isoppanol kapena 2-propanol, ndi nthano wamba yopanga ndi njira ya c3h8o. Mankhwala ake ndi mikhalidwe yakuthupi yakhala ikukhudzidwa pakati pa akatswiri azamankhwala ndi anthu omwe ali chimodzimodzi. Funso lina lochititsa chidwi kwambiri ndikwakuti limasungunuka m'madzi. Kuti timvetse funso ili, tiyenera kuyesedwa ndi chemistry ya chemistry ndikuwona kuyanjana pakati pa mamolekyulu awiriwa.

Kusungunuka kwa chinthu chilichonse choperekedwa kumatsimikiziridwa ndi kuyanjana pakati pa solute ndi solventsklules. Pankhani ya isopropyl mowa ndi madzi, kuyanjana kumeneku ndi kolumikizana ndi mphamvu ndi van der walkes. Kuledzera kwa isopropyl kuli ndi gulu la hydroxyl (--Oh) lomwe limapanga ma bondo a hydrogen ndi mamolekyulu amadzi, koma ma hydrocabon amapeputsa madzi. Kulefukira konse kwa isopropyl mowa kumadzi kumachitika chifukwa cha malire a mphamvu ziwirizi.

Chosangalatsa ndichakuti, kusungunuka kwa isopropyl mowa kumadzi kumadalira kutentha ndi kuvuta. Mu firiji yotentha ndi pansipa, isopropyl imasungunuka pang'ono m'madzi, ndikusungunuka kwa 20% pambale 20 ° C. Kutentha kumawonjezeka, kusungunuka kumachepa. Pa ndende zambiri komanso kutentha pang'ono, kulekanitsidwa kwa gawo patatha kuchitika, chifukwa cha zigawo ziwiri zosiyanasiyana, chimodzi cholemera ku isopropyl mowa komanso wina wolemera m'madzi.

Kupezeka kwa mitundu ina kapena magalamumu amathanso kukhudza kusungunuka kwa isopropyl mowa. Mwachitsanzo, okonda okonda omwe ali ndi mowa wa isopropyl kapena madzi amatha kusintha kusungunuka kwawo. Katunduyu amapeza ntchito m'magawo osiyanasiyana monga zodzoladzola, mankhwala opangira mankhwala, ndi agrochemicals, ndipo oyendetsa maorchemical nthawi zambiri amagwiritsidwa ntchito kupititsa patsogolo zosakaniza zosungunuka.

Pomaliza, kusungunuka kwa isopropyl kumadzi ndi chinthu chovuta kwambiri chomwe chimakhudzanso malire pakati pa nyumba ya hydrogen ndi a van Der Waals Force. Ngakhale kuti imasungunuka pang'ono firiji ndi pansipa, zinthu monga kutentha, kukhazikika, ndipo kupezeka kwa zinthu zina kungakhudze kwambiri kusandulika kwake. Kuzindikira bwino kwa izi ndi momwe zinthu ndizofunikira pakugwiritsa ntchito moyenera kwa isopropyl mowa pamapulogalamu osiyanasiyana.
