The raw product(carrots) was extracted using simple distillation. The purity of the product will be characterized using percent yield‚ thin layer chromatography‚ Beer’s Law‚ and UV-vis. Beer’s law is used because in this experiment we are comparing our extraction of B-Carotene to the Stock B-Carotene. Beer’s law shows that

Introduction The purpose of this lab is to synthesize Lidocaine from 2‚6-dimethylaniline‚ using diethyl amine‚ 2-chloroacetyl chloride‚ acetic acid‚ and toluene. The Lidocaine was made by adding 2‚6-dimethylaniline to 2-chloroacetyl chloride in acetic acid. Sodium acetate is added in order to make the compound soluble. The product is dried‚ then treated with diethyl amine and toluene. This is refluxed using a water-cooled reflux condenser. The vapor is condensed by the cold water as the compound

Moreover‚ the melting point matches the theoretical value‚ thus the final product formed was successfully diphenylacetylene. However‚ the percent purity of the reaction is completely out of proportion‚ hence there are many errors that took place during the UV-vis analysis. An adequate percent yield was obtained from this experiment‚ but the relativity low value can be explained by the loss of product
