    DISTILLATION ABSTRACT Distillation‚ one of the most significant method for separating a liquid mixture and its components‚ is a process that relies on differences by the ease of vaporization of the components. The purpose of this process is either the separation of a mixture of volatile components from nonvolatile materials is carried out by a simple distillation in which the material is placed to distill and heated‚ the vapor from the substance is removed and condensed. In this activity

    The obtained mass of benzocaine and benzoic acid mixture was measured to be 2.075 grams. Following being dried for a week the mass of benzocaine was recorded to be 0.250 grams‚ and benzoic acid was recorded to be 0.600 grams. The melting point range of benzocaine was measured to be 89.5°C-91.5°C‚ while benzoic acid’s melting point range was measured to be 129°C-131.3°C. The percent mass recovered was calculated to be 40.96% for the experiment. Table 1 illustrates the collected information. Starting
