In which temparature toluene is liquid
Web• Record the temperature as the first drops of liquid are collected. This temperature reflects the boiling point of the cyclohexane distillate. • Collect distillate until distillation of cyclohexane stops and the observed temperature drops (approximately 7 mL) • Do not distill to dryness. • Turn off the sand bath. WebAt temperatures above 300°F (149°C) a chlorine/steel fire can result. It is important to make sure steel in chlorine service does not go above this temperature either through internal/external heating or mechanical abrasion.
