| Separation of Nitrophenols | | | | Abstract: Using a micro scale steam distillation we separated ortho and para-nitrophenol from a mixture that was already made. After the para and ortho were separated we measured their melting points and compared it to the literature values for purity. For ortho-nitrophenol we had 60% recovery and for para 160% recovery. Our melting point ranges were ortho: 45-46°C and para 64-95°C. Introduction: Nitration: In phenols‚ -OH group strongly

There was distillation of liquid in the lower ranges of around 30°C-40°C. This indicates that there was no side reactions‚ as none of the side product was retrieved. Liquid distill at about 82.8°C‚ which indicates that 2-chloro-2-methylbutane was the only product of this reaction. The theoretical yield was calculated using 2-methyl-2-butanol as the limited reagent in the reaction‚ and was found to be 7.80 grams of 2-chloro-2-methylbutane. The experimental yield that was retrieved was found to be

This lab will help guide you in the direction to predict the regioselectivity and activation vs. deactivating powers of the nitro-group. Gas Chromatography will be used to analyze compounds that can be vaporized without being decomposed. GC is also used to check the purity of a substance‚ and separating the

17‚ 2012 Abstract The distillation process was successfully done because of the separation of water from the acetone. When the distillate was lighted with the matchstick it produced flame which indicates that there was more presence of acetone than water. When the sodium nitroprusside‚ sodium hydroxide and glacial acetic acid was added to the distillate‚ it turned to violet. This means that there is the presence of ketone. Introduction Distillation is the process heating a liquid

utilized by removing water from the products. As a result‚ the reaction as a whole shifts the left producing more isoamyl acetate to try and balance the reaction once again. Once the product was collected‚ it was purified through means of fractional distillation. Finally to characterize the product‚ and assess its purity‚ IR and NMR spectroscopy were taken.

Introduction The SN2 reaction is a bimolecular nucleophilic substitution reaction where the nucleophile (a molecule with a free pair of electrons) reacts with an alkyl halide and replaces the halogen (for more details see Solomons and Fryle‚ Chapter 6). The nucleophile approaches

Melting point 1. What two effects do impurities have on the melting point of an organic compound? Soluble impurities affect the melting point of a solid in the following manner. a. The presence of an impurity in the molten compound reduces its vapor pressure thus lowering the melting point of the compound. b. Broaden the melting point range. 2. For what tow purpose are melting points routinely used a. To determine the identity of an organic solid. b. To determine the purity of an organic solid
