out. Sulfuric acid is first added to the 1-bromobutane layer to remove any leftover starting material and after the 1-bromobutane layer is isolated sodium hydroxide solution is added to remove any remaining acid. Drying using anhydrous calcium chloride pellets is then used to remove any remaining water in the solution and then the simple distillation

Abstract A Friedel-Crafts alkylation was performed by adding t-butyl alcohol to p-dimethoxybenzene in order to produce 1‚4-di-t-butyl-2‚5-dimethoxybenzene. This reaction yielded 0.009g of 1‚4-di-t-butyl-2‚5-dimethoxybenzene having a percent yield of 5%‚ and a melting point range of 54.8°C-56.9°C. Introduction This reaction is designed to put functional groups onto aromatic rings. This is done through an electrophilic aromatic substitution where a positive species is strong enough to pull electrons

different extraction techniques and a solvent‚ Tert-butylmethylether (TBME). Solid-liquid extraction is just like making coffee or tea; extracting liquid components from a solid using a solvent. This experiment involved extracting pure solid Trimyristan from ground nutmeg using several separation techniques such as using a reflux apparatus PROCEDURE 2.5 mg of Nutmeg was obtained from a known source and added to a 100 ml round bottom flask. 40 ml of Tert-butylmethylether was added to the

Part Ca)Up until the 1940’s rubber had only been obtained from the latex of rubber trees(Hevea brasiliensis) in plantations situated in tropical areas such as Malaya and Burma. The demand for rubber increased significantly during world war 2 as rubber was needed for tyres of military vehicles and the supply was interrupted by the conflict between the countries. Scientists in Germany and the US developed synthetic polymers that could replace rubber. Even after the war ended the traditional sources

AbstractThis experiment investigated the amount of DNA extracted from strawberries. This was done by using the independent variable of alcohol to affect the dependant variable of the amount of DNA extracted. This was done to find out if primary or secondary alcohol would create more DNA precipitate than the other. For this the primary alcohols used were; methanol and ethanol‚ and the secondary alcohol was; isopropyl. Of this the secondary alcohol‚ isopropyl was discovered to be the most effect alcohol

Alkylation Reaction Introduction: In the experiment we will create 1‚4-Di-t-Butyl-2‚5-Dimethoxybenzene by performing a Friedel-Crafts reaction on 1‚4-Dimethoxybenzene. In the reaction a t-butyl carbocation will be added on to the 1‚4-Dimethoxybenzene. The t-butyl carbocation will be formed by a reaction of t-butyl alcohol with sulfuric acid. To perform the reaction we will create a mixture of the 1‚4-Dimethoxybenzene‚ t-butyl alcohol with acetic acid. To this mixture we will add sulfuric acid dropwise
