CHMB41H3 Study Guide - Final Guide: Sodium Hydroxide, Eutectic System, Fractional Distillation
Document Summary
Bulb is under side arm of distillate head. Separating liquids must have a difference of 20 deg c. Grease joints, add new boiling chips, put foil on fractionating column, bulb position, clamp rb flask, clamp condenser, graduated cylinder position. Trimyristine extracted from myristica fragrans from myristic acid (iii) and glycerol. Reflux: conservation of liquid volume in the cycle of evaporating liquid to vapour and condensing again to speed up reaction (thru heat) Gravity filtration: use glass pipet because there is no loss of yield, unlike filter paper. Used acetone because water has low bp and low mp (evaporate) Prelab: use diethyl ether vs acetone because s in ether, i in acetone --> force out trymyristine crystals, fat vs oil --> liquid or solid at room temp. Trimyristine is saturated (no double bonds: impurities in a mixture act as impurities on each other --> no crystals.
