Acetanilide is an important organic compound which is vastly used in the pharmaceutical industry. It is an odorless, white, solid or flaky compound. Its preparation method is used to introduce students with synthesis of organic compounds in chemistry labs. It is prepared by acetylation of aniline.The overall reaction scheme for acetanilide synthesis The acetanilide is soluble in hot water (-5.5 g/100 mL) and scarcely soluble in cold (-0.5 g/100 mL). We will use this property to purify it by recrystallization. Recrystallization is a common purification technique used in an organic chemistry laboratory.

Discussion: This mechanism is a classic example of electrophilic aromatic substitution. An amine may lead to di- and tri- substituted products. If an amide is used in place of the amine,Preparation of Acetanilide. Learning Activity 1 Preparation of Acetanilide Abstract Recrystallization is a common method of purifying organic substances through the difference in solubility at different temperature. In this experiment, acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heating water bath.Synthesis of Acetanilide By: Rick Whitely April 9, 2013 Organic Chemistry Lab 1; Professor J.

Gently warm the mixture to dissolve acetanilide completely. Cool the solution and add concentrated sulphuric acid slowly with constant stirring.Acetanilide is an important organic compound which is vastly used in the pharmaceutical industry. It is an odorless, white, solid or flaky compound. Its preparation method is used to introduce students with synthesis of organic compounds in chemistry labs. It is prepared by acetylation of aniline.So the theoretical yield of acetanilide is 0.160g. If the student had a perfect lab day he or she would collect 0.160g and have a 100%.percent yield. But the student only collected 0.132g of acetanilide. To get the percent yield, we calculate 0.132g as a percent of 0.160g: Q: What happens if you add too much solvent during recrystallization?Acetanilide is an important organic compound which is vastly used in the pharmaceutical industry.
