Preparation of Caprolactam Sample Clauses

Preparation of Caprolactam. Add 10 mL of concentrated sulphuric acid in a 500 mL beaker. While stirring, slowly add 5 g of cyclohexanone oxime (a) [Note 2] to the mixture. Carry out this process in a fume cupboard because the reaction is exothermic and liberates heat. If heat is not liberated, heat the mixture on a steam bath for 5 minutes. Let the reaction subsides, and then cool the beaker in an ice-bath. Pour the reaction mixture into a beaker containing 150 g of ice. Cool the beaker in an ice-bath, and slowly add potassium hydroxide solution (25%) until the mixture becomes alkaline. Make sure that the temperature of the reaction does not exceed 10 °C. If precipitate of potassium sulphate is formed, add water or filter the precipitate, wash with dichloromethane and combine the dichloromethane wash with dichloromethane extracts. Extract the alkaline solution with dichloromethane (3 x 75 mL), wash the dichloromethane layer with water and dried over anhydrous magnesium sulphate. Remove the solvent using rotary evaporator and extract crude oily product with boiling petroleum ether (60−80 °C). Cool the petroleum-ether extracts and caprolactam will crystallise out as colourless crystals. Record the melting point and percentage of product obtained. Interpret the infrared spectrum of your product. 1. Hydroxylamine is very toxic and be careful when handling it. 2. It is essential that the oxime has been sufficiently dried, else the hygroscopic effect of sulphuric acid is insufficient to initiate the rearrangement. In view of hydrogen bonding, therefore, it is not recommended to convert the oxime at the preparation day. 1. What is the role of sodium acetate in the formation of oxime? 2. Write a mechanism for the formation of cyclohexanone oxime.
