Introduction The American Chemical Society databases were investigated through Scifinder Scholar Version X to find any information about Butyl 2-Cyano-(3‚5 dichloro-phenyl)-2-propenoate. There was no previous information present. Then‚ the microscale synthesis and characterization of Butyl 2-Cyano-(3‚5 dichloro-phenyl)-2-propenoate was conducted with the base catalyzed Knoevengael condensation of the butyl cyanoacetate and corresponding aldehyde (gkharas/235_14F/235_14F_Lab_2.pdf) and analysis. The elemental

Synthesis of Isopentyl Acetate Abstract The purpose of this experiment was to produce isopentyl acetate‚ banana oil. Acetic acid and isoamyl alcohol were used to synthesize isopentyl acetate. The techniques used for the separation and purification of isopentyl acetate were reflux‚ liquid-liquid extraction‚ neutralization and distillation. The identification of isopentyl acetate was based on boiling points and an infrared spectrum. This experiment resulted in a 11.68% yield. The reactants
