Malonic Ester Synthesis Of Diethyl N Butylmalonate

acid was synthesized in a multi-step process that involved the synthesis of three intermediates – diethyl n-butylmalonate, potassium n-butylmalonate, and n-butyl malonic acid respectively. An IR was used to characterize the starting material, n-bromobutane, and the first intermediate, diethyl n-butylmalonate; while IR and NMR were used to characterize the final product, caproic acid. Reactions, Mechanism and Theory Caproic acid a.k.a n-hexanoic acid is a carboxylic acid derived from hexane which...

Synthesis of Esters

SYNTHESIS OF ESTERS USING GREEN AND NON-GREEN CHEMISTRY Abstract Esters are a class of organic compounds with the general formula RCOOR’. Ester also contributes the flavor and aromas in fruits and flowers. The esterification reactions will use in the procedure, which are the interaction of a carboxylic acid with an alcohol, aided by an inorganic acid catalyst (H2SO4). Moreover, the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of...

Experiment 7: Diethyl n- Butylmalonate Lab Partner: Reference: Williamson K.L., & Masters, K.M. (2011).”Diethyl n- Butylmalonate”. Macroscale and Microscale Organic Experiments ( 6th edition pp. 531-534) Belmont, CA: Brooks Cole. Purpose: In this experiment, potassium carbonate combined with a quaternary ammonium salt to form a strong base. The strong base created an anion from an ester of malonic acid. The ion reacted with bromobutane which was also...

Synthesis of N-Propanol

Preparation of Fruit Flavors (Pear) Abstract. In this experiment an assigned Ester is prepared, particularly n-Propanol. The Preparation was done via Fischer reaction. In this reaction, a reflux set-up is required. The reflux set-up was used in the liquid-liquid extraction. After adding an immiscible solution to the compound containing n-Propanol, the mixture now will have two layer: the Organic and Aqueous layer. The organic layer is the extract needed and its % yield is computed resulting to...

Synthesis Of DEET

 Synthesis of DEET Abstract: For this experiment m-toluic acid was reacted with thionyl chloride resulting in a nucleophilic acyl substitution which could then be used to create DEET with excess diethyl amine (Figure 1). This was done by adding diethyl amine drop wise using a seperatory funnel which resulted in a gas formation which was controlled with a condenser attached to a gas vacuum. The resulting mixture was then washed to remove excess acids and bases and rotovapped. DEET was synthesized...

Tie Dye Grignard Synthesis

Tie-Dye Grignard Synthesis Abstract: 4-Bromo-N,N-dimethylaniline underwent a Grignard reaction with diethyl carbonate to produce a type of the tie-dye chemical triarylmethane. This specific triarylmethane produces a vivid crystal violet color when dyed. The experiment was first heated under reflux to produce the necessary Grignard reagent as a grey liquid. It was then reacted with diethyl carbonate and hydrochloric acid to produce crystal violet. The resulting chemical was very absorbent to...

Grignard Synthesis of Triphenylmethanol

The Grignard Synthesis of Triphenylmethanol Abstract: Grignard synthesis of triphenylmethanol was achieved by use of the Grignard reagent phenyl magesium brominde. The organometallic grignard reagent was synthesized by use of a reflux apparatus recrystallization techniques. Once synthesized it was used in a Grignard reaction that involved nucleophilic addition to a carbonyl in order to make triphenylmethanol. The final product was solidified and recrystallized and spectral data was...

Esterification - Synthesis of Methyl Benzoate

industrial settings due to the simplified synthesis and safety parameters of the overall reaction. Both benzoic acid and methanol are relatively cheap to obtain from a commercial source as well as being easy to store with a relatively long shelf life. The Fischer esterification method is a fundamental and important synthesis process in training our future chemists in both commercial and academic employment and principles. By utilizing this method of synthesis, the chemist has the knowledge to utilize...
