November 15‚ 2007 Synthesis of 1-Bromobutane Introduction: The purpose of this experiment is to synthesize 1-bromobutane from 1-butanol and sodium bromide. In order for this reaction to reach completion there are four major operations that need to be performed. The four major operations include refluxing‚ simple distillation‚ separation‚ and drying. To begin‚ in order for the compounds to react they will be dissolved in water and sulfuric acid will be added. The addition of sulfuric acid will

avoid large heat losses. The cold feed is first preheated to its boiling point using steam as heating medium and then vaporized in a thermosyphon reboiler utilizing the heat contained in the reaction products. The vapor‚ which has entrained liquid is removed from the knock out drum‚ and then heated to reaction temperature using flue gas. COLD FEED PREHEATER:Total feed = 23412.14+2605.77 kg = 26017.91 kg 26017.91 kg per hour of 2-butanol is to be preheated from 250C it boiling point 107.50C. Heat

While attending Indiana State University‚ one of the first sculptures I took an interest in was the Via Solaris. “Via Solaris‚” Latin for the way or road of the sun. The sculpture is about 20-feet tall and made of bronze and steel. Via Solaris was created by John Van Alstine (b. 1952)‚ an American sculptor living and working in New York State best known for stone and metal abstract sculptures exhibiting exceptional balance and poise. The sculpture is located on the north side of Stalker Hall on

Synthesis of 3‚4-dihydro-3-(p-methylphenyl)-1‚2-(2h)-benzoxazine involves the nucleophillic addition of the 1 °amine group upon the carbonyly group of the salicylaldehyde‚ the reduction of imine to amine and the addition of paraformaldehyde to proceed ring closure. The experiment prepared the product through Mannich reaction‚ a multicomponent condensation synthesis between ketone‚ aldehydes‚ enols and amines.

The chloride shift is basically an exchange of chloride ions through the capillaries of the system circuit. In the blood plasma‚ there is large amount of carbonic acid and when there is an increase in carbonic acid than the balance of hydrogen ions and carbonate ions dissociate to maintain a balance of homeostasis in the pH of the blood. The red blood cells help to maintain this system by buffering the system of carbonic acid and causing detachment of the above ions. The release and detachment is

Synthesis of Isopentyl Acetate (Banana Oil) Using a Fischer Esterification Reaction Zhenshu Wang (Stan) TA: Aaron League September 23‚ 2012 Purpose: The purpose of the experiment was to perform the acid-catalyzed Fischer Esterification of acetic acid and isopentyl alcohol to form isopentyl acetate‚ or banana oil‚ which is used in flavor industries. The equilibrium of the reaction was changed by adding an excess amount of acetic acid. The reaction was refluxed and product was purified by extraction

melted at 158.5-162 degrees Celsius. Introduction: Grignard reagents are the most useful way to form primary‚ secondary or tertiary alcohols from a carbonyl group. The Grignard reaction involves the nucleophilic addition of an organomagenesium complex to a carbonyl carbon followed by acid work-up. This reaction involves a single electron transfer between the carbonyl group and the grignard reagent. Once the Grignard reagent is synthesized it can work as a base by abstracting a proton or it can
