Computed by PubChem 2.1 (PubChem release 2021.05.07)It's best to start with the bleach and acetone chilled even if you're using ice because the reaction will cause the mixture to heat up by at least 85 degrees. The higher concentrate bleach you use, the hotter it gets. The ratio for making chloroform needs to be 1 part acetone to 50 parts bleach.Regression coefficients were determined for CCl4, CHCl3, and CCl4-CHCl3. All results were significant (p less than 0.0001) and implied that CCl4 was a more potent hepatotoxin in vitro than CHCl3. The RSM analysis also suggested that combinations of CHCl3 and CCl4 have greater than additive effects on MTT reduction and [3H]choline incorporation.Because three are no charges on atoms, we do not need to do the step of reducing charges on atoms by converting lone pairs to bonds.
