Preparation Of Phenyl Benzoate

EXPERIMENT ( 3 ) progeny :The expression of Phenyl Benzoate from benzoyl chloride Introduction :The facility of phenyl benzoate (ester) from hydroxybenzene and benzoyl chloride is an esterification. In this experiment, you argon requested to prepare and distil phenyl benzoate by some techniques. Chemicals :Phenol, Benzoyl chloride, deoxidise NaOH, Methanol Procedures :1.Dissolve 1 g carbolic acid in 15 cm3 deprave NaOH victimisation a 50 cm3 quickfit flaskful. 2.Add 2 cm3 benzoyl chloride, stopper the flask and perk up cleverly for 15 minutes. At the polish off of this time, a significantness output should be obtained. 3.Filter off the solid at the affectionateness, breaking up any lumps on the interpenetrate cover with a spatula. lavation thoroughly with water and drain. 4.Recrystallise the approximative ester from wood spirit using a quantity of igneous solvent somewhat twice the tokenish required for complete beginning (This is to ensure that the phenyl benzoate does not speciate until the temperature of the final result has fallen below the resolve portend of the ester). Phenyl benzoate separates as dull crystals. 5.Determine the melting present of the product. Results : apply (mass in gram) = __________________0.

128 g_____________________ Melting point of pure phenyl benzoate (OC) = ___________70O______________ Melting point of your phenyl benzoate (OC) = ___________69O______________ Questions : 1.why do we use NaOH answer to dissolve phenol quite a than water in standard 1 ? Because NaOH can be use to change the phenol to ion form, which can be more(prenominal) soluble in the aqueous solution. 2. rotter we use ethanoyl chloride rather of benzoyl chloride ? let off briefly. No. Because it will set up another compound, phenyl ethanoate. 3. wherefore do we filter the product using a pump rather than filtration under gravity in step 3 ?
