    experiment aims to find the concentration of acetic acid in the vinegar sample by titrating it to a standardized NaOH solution, a base solution. A standardized 0.100 M NaOH solution was prepared from an available concentration of NaOH specifically a 1.00 M NaOH. The volume of the standardized solution (titrant) used which is 0.100 L was calculated using the M 1 V 1 = M 2 V 2 relationship. It was then gradually added to the vinegar solution until the acid-base reaction was completely neutralized.

    Since the extraction temperature of acetic acid extraction prior to terephthalic acid production are desired at T = 313.2 K and atmospheric pressure. The temperature has been carried out since the aqueous solution that fed to extractor column is originally coming from the top product of distillation column in the upstream process, also keeping the temperature at 313.2 K to avoid the crystallization of acetic acid during the process. Therefore, the experimental liquid-liquid equilibrium data for the

    920 Words  | 4 Pages

    Conclusions In this experiment, acetanilide was synthesized via nucleophilic acyl substitution from both acetic anhydride and aniline. During this reaction, aniline acts as the nucleophile and acyl (CH3CO-) group from acetic anhydride acts as the electrophile. The hydrogen atom of –NH2 group is replaced by the acyl group. The crude product contained acetanilide, and acetic acid, which was the impurity. Recrystallization, which was used to purify the contaminated acetanilide, required a suitable

    equivalents of liquid acetic anhydride to 1.8 equivalents of phosphoric acid and concluded with an aqueous workup with NaOH. The initial reaction mixture containing ferrocene, acetic anhydride, and phosphate acid was mixed on a hot stir plate. During this period, reflux was observed, and the mixture appeared dark brown in color. To quench the reaction, the reaction mixture was transferred onto ice. NaOH was slowly added into the mixture, which resulted in acetic acid byproduct from the acetic anhydride reactant/solvent

    Generally, acetone can be produced in various ways. Prior to world war, acetone is produced by dry distillation of calcium acetate. Early 1920s onwards, acetone is mainly produced by dehydrogenation of isopropyl alcohol. During World War II, acetone is produced by fermentation process and few ethanol processes while in late 1950s and early 1960s, acetone is produced by cumene-hydroperoxide with phenol as main product. In mid 1960, acetone is produced by direct oxidation of propylene. In this part
