Mixtures of excess benzoic acid & water form 2 liquid phases beginning at 89.7 °C; the two phases unite at critical solution temperature of 117.2 °C; solubility in water increased by alkaline substances.
15 Ιαν 2018 · The focus of the work is to provide model predictions that are obtained completely independent of any experimental solubility data, to address the non-ideality of acetanilide + water mixtures and to validate the assumptions behind the estimation of the PC-SAFT parameters.
Melting point: 113–115 °C (235–239 °F; 386–388 K) Boiling point: 304 °C (579 °F; 577 K)
Introduction. The goals of this lab are to perform a base extraction of benzoic acid from acetanilide, purify the solid by recrystallization, isolate the crystals, and obtain a melting point of the crystalline solid. Extraction is the method of isolating compounds from one liquid to another.
For example, the melting points of samples of benzoic acid contaminated with known quantities of acetanilide are summarized in Table 6.1. As the quantity of impurity increased, melting began at a lower temperature, and the breadth of the melting range increased.
1 Σεπ 2017 · Two binary interaction parameters between water and/or benzoic acid were used to model vapor-liquid and liquid-liquid equilibria of water and/or benzoic acid between 280 and 413 K.
PROCEDURE: Grind 1.0g of benzoic acid and acetanilide in a mortar and determine the mixture’s melting point. Also determine the melting point of each individual sample.
