Heat the mixture with magnetic stir SYNTHESIS The reaction of formation of the aspirin takes place by treatment of salicylic acid with acetic anhydride, as shown in Scheme 1. var path = 'hr' + 'ef' + '='; Benzoic acid is not very soluble in cold water, but it is soluble in hot water. WebGive the m.p. The specific substance being tested first, is the organic compound benzoic acid. This is Benzoic Acid. WebIn that Internship i worked in production department. Its vapor has an unusual pungent odor that causes sneezing and coughing. After preparing the mixture, set up an apparatus for simple reflux. Its classified as a carboxylic acid because it has a carbon group in its structure, which is the COOH group. Industrially, benzoic acid can be prepared by employing oxygen gas for the partial oxidation of toluene. WebThe unknown concentration of benzoic acid used when titrated with standardized 0.1031M NaOH and the solubility was calculated at two different temperatures (20 C and 30 C). For the time being I must improvise my set up for vacuum filtration. Here is a picture of the Benzoic Acid after filtration: Toluene and water are immiscible. Benzoic acid is an important precursor for the industrial synthesis of many other organic substances. A process for the preparation of a compound of the formula ##STR1## in which X 1 and X 2 each independently is chlorine or fluorine, and Y is chlorine, bromine, fluorine or iodine, comprising subjecting a compound of the formula ##STR2## to a Sandmeyer or Balz-Schiemann reaction thereby to produce a carboxylic acid of the formula ##STR3## and converting the carboxylic I plan to use benzoic acid to synthesize Benzamide and eventually aniline. , | 0096176817976 1- , | 0096176817976 .. .., | 0096176817976 , | 0096176817976 , | 0096176817976 , 0096176817976| ( ) , 0096176817976| , 0096176817976| : , ( )| 0096176817976 , - 0096176817976 + , | 0096176817976 , | 0096176817976 , | 0096176817976 : , | 0096176817976 , | 0096176817976 , | 0096176817976 , | 0096176817976 ( ) : , | 0096176817976 , | 0096176817976 , | 0096176817976 , 0096176817976| ( , 0096176817976| 5 ( , 0096176817976| , 0096176817976| , 0096176817976| , 0096176817976| , 0096176817976| , 0096176817976- , 0096176817976| , 0096176817976| 7 , 0096176817976| 3 , 0096176817976| , | 0096176817976 4 , 0096176817976| , 0096176817976| 7 , 0096176817976| , | 0096176817976 , 0096176817976| 7 , 0096176817976- , | 0096176817976 , | 0096176817976 , | 0096176817976 , | 0096176817976 , | 0096176817976 1000 , | 0096176817976 7 , | 0096176817976 , | 0096176817976 (313) , 0096176817976| 21 , 0096176817976| 21 , 0096176817976- 1- , 0096176817976| , - 0096176817976 , | 0096176817976 , | 0096176817976 21 , | 0096176817976 : , | 0096176817976 , 0096176817976| , 0096176817976| , 0096176817976| : : 1- , 0096176817976| , 0096176817976| , 0096176817976| 1- : , 0096176817976| 40 40 ( , 0096176817976| ( 3 , 0096176817976| , 0096176817976| , 0096176817976| 7 , 0096176817976| , 0096176817976| 1040, 0096176817976 , 0096176817976| , 0096176817976| , 0096176817976| : , 0096176817976| 2 2 2 2 2 2 2 , 0096176817976| ( , 0096176817976| , 0096176817976| , 0096176817976| 40 40 ( , 0096176817976| , 0096176817976| } (, 0096176817976| 40 40 ( , 0096176817976| = , 0096176817976| 20 , 0096176817976| , 0096176817976| 1001 100 , 0096176817976| , 0096176817976| .
