4 de jul. de 2008 · This paper explores the design and control of the maximum-boiling azeotropic acetone/chloroform distillation system. The normal boiling points of the two pure components are 329.4 and 334.3 K, while the azeotropic boils at 337.6 K at 1 atm with a composition of 34.09 mol % acetone.

Sodium hypochlorite solution (chlorine bleach) mixed with common household liquids such as acetone, methyl ethyl ketone, ethanol, or isopropyl alcohol can produce some chloroform, in addition to other compounds, such as chloroacetone or dichloroacetone.
1 de ene. de 1980 · The physical parameters of chloroform: (d = 1.4799 g cm~, 45 = 1.4421) and of acetone: (d = 0.7862 g cm3, 45 = 1.3 560) are in satisfactory agreement with other investigations, especially for chloroform. There is much disagreement in the literature concerning the density of acetone.
15 de ago. de 2019 · The NRTL-SAC model could not appropriately predict the maximum azeotrope temperature systems, in particular for acetone-chloroform, chloroform-methyl acetate, and chloroform-diethyl amine systems. For these systems, the NRTL-SAC model gave a minimum azeotrope temperature.
1 de nov. de 2005 · Pure acetone boils at 51.5 °C (at 733 mmHg) and pure chloroform boils at 56.5 °C, while azeotrope boils at 60 °C, therefore, acetone and chloroform's boiling point rise 3.5 and 8.5 °C, respectively, which means stronger attraction forces between two molecules due to the azeotrope formation.
6 de nov. de 2008 · Chloroform, a C-H hydrogen bond donor, can form weak hydrogen bonded complexes with acetone and with dimethylsulfoxide (DMSO). When chloroform is dissolved in a mixed solvent consisting of acetone and DMSO, both types of hydrogen bonded complexes exist.
