Distilled Water (regular tap water can also be used without any visual loss of yield); Toluene is highly flammable, irritant to the skin and mildly toxic when inhaled. If the filtrate is colorless youre good to go. . Benzoic acid can be made very easily from toluene. Materials and methods 2.1. Synthesis of 4-Nitrobenzoic acid (a) Friedel-Crafts alkylation of benzene (b) Nitration of toluene (c). Kim Shui Instagram, Web0.962 at 95C Procedures : Observations from Sim/Vid/HnOt We have mixture that contains of benzoic acid 0.504 g which is white crystalline solid, p-nitroaniline 0.502g that is yellow crystalline, and naphthalene 0.508g that is white crystalline solid. Having excess Toluene also guarantees that all Potassium Permanganate gets reduced, avoiding additional separation processes to remove it. Reaction/Summary In Experiment One we will be recrystallizing Benzoic Acid from water. 0000003477 00000 n Physical properties of Benzoic Acid. This is not strong. The amount obtained was 1,9g.
