[[pentana]] dan [[heksana]], lan uga larut ing senyawa klorida alifatik kaya ta [[1,1,1-trikloroetana|trikloroetana]] lan [[tetrakloroetilena]].<ref name=merck>{{cite book |author=Windholz, Martha |title=The Merck index: an encyclopedia of chemicals and drugs |publisher=Merck |location=Rahway, N.J., U.S.A |year=1976 |isbn=0-911910-26-3 |edition=9th}}</ref>
Campuran etanol-banyu nduwé volume kang luwih cilik saka gunggung cuwèran loro mau kanthi kapisah. Campuran etanol lan banyu kanthi [[volume]] kang padha bakal ngasilaké campuran kang volumené mung tikel 1,92 saka gunggung volume wiwitan.<ref name=crc>''CRC Handbook of Chemistry'', 44th ed.</ref><ref name=ChemTech>{{cite encyclopedia |chapter=Ethanol |title=[[#Encyc_Chem|Encyclopedia of chemical technology]] |year=1991 |pages=813 |volume=9}}</ref> Pencampuran etanol dan air bersifat [[eksotermik]] dengan ènergi
Campuran etanol lan air bakal mbentuk [[azeotrop]] hingan watara kanthi perbandingan 89 mol% etanol lan 11 mol% banyu.<ref>{{cite journal |author=Lei Z, Wang H, Zhou R, Duan Z |title= Influence of salt added to solvent on extractive distillation|journal=Chem Eng J. |volume=87 |issue= |pages=149–56 |year=2002 |doi=10.1016/S1385-8947(01)00211-X}}</ref>. Perbandhingan iki uga bisa dinyatakaké minangka 96% volume etanol lan 4% volume banyu ing tekanan normal lan T = 351 K. Komposisi azeotropik iki gumantung banget karo suhu lan tekanan.
