Cyclohexanol freezing point
WebScience Chemistry Cyclohexanol, C H,,OH, is sometimes used as the solvent in molecular weight determinations by freezing-point depression. If 0.253 g of benzoic acid, C H COOH, dissolved in 12.45 g of cyclohexanol lowered the freezing-point of pure cyclohexanol by 6.55°C, what is the molal freezing-point constant, Ke, of this solvent? 3. http://www.ciscochem.com/assets/cyclohexane-sds.pdf

Cyclohexanol is moderately toxic: the Threshold Limit Value for the vapor for 8 h is 50 ppm. The IDLH concentration is set at 400 ppm, based on studies on the acute oral toxicity in animals. Few studies have been done on its carcinogenicity, but one study on rats found it to have co-carcinogenic effects.
