mixture is dissolved in diethyl ether (common name is ether). Both components are soluble in this solvent. Then a 1 M NaOH solution is used to extract the benzoic acid in the form of its water-soluble salt‚ sodium benzoate (three extractions to ensure complete removal)‚ leaving the neutral compound in the ether layer. The three aqueous extracts are combined and the two components are recovered as follow: 1. The neutral compound by washing‚ drying and evaporating the ether layer. 2. Benzoic acid by

I will be telling you my short little paper on the History of Anesthesia. I will be telling what some terms mean that will be used in anesthesia history. Also I will be telling a some dates from years before our time on how anesthesia came from and who was there‚ and what drugs came out. First I will be starting out with several definition of the term anesthesia. The absence of normal sensitiation‚ especially to pain‚ as induced by an anesthetic substance or by hypnosis or as occurs

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

Megan Entwistle‚ Maria Amos‚ and Paul Golubic CHEM 0330 Organic Lab 1 Sodium Borohydride Reduction: Diphenylmethanol from Benzophenone 11/16/11 Introduction Redox (shorthand for REDuction-OXidation) reactions are chemical reactions in which the oxidation state (or oxidation number) of atoms has changed. Oxidation can be observed through the loss of electrons or an increase in oxidation state by an atom‚ ion or molecule. Reduction describes the gain of electrons or decrease in oxidation state
