The products of all four reactions will be analyzed with gas chromatography‚ which separates organic compounds to see how each reaction’s product are formed under the constraints of stereochemistry and regiochemistry. In a general elimination reaction‚ an atom or group of atoms is removed from a carbon‚ along with an

Theory: By Using specific methods of compounds detection‚ we can match an unknown compound with a known compound because similar compounds will display similar characteristics. In this experiment‚ identifications of the unknown ketone was accomplished using thin layer chromatography‚ melting point‚ and NMR spectrometry. Thin layer chromatography is very

the retention time of polar molecules is shorter because they pass through the column faster. Reversed phase HPLC is the most commonly used form of HPLC which separate solutes based on non-polar differences. In this experiment‚ reverse phase chromatography was used. The more polar antioxidant is expected to elute first due to the weak attraction to the non-polar column. Figure 2 below shows the structures of the two antioxidants. Both antioxidants contain a benzene ring and a hydroxyl group. However

the sample for gas chromatography. Introduction: Distillation has been used since antiquity to separate the components of mixtures. This method has been used to manufacture different organic chemicals but the most recent application is the refining of petroleum in order to produce fuels‚ lubricants and petrochemicals. In this experiments‚ the separation of 2 distilates were carried out using the differences in boiling points and the data was used for a gas chromatography test. Objectives:

of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of photons‚ is actively captured

All this validation methods are applicable to bio-analytical methods such as Gas Chromatography and High Performance Liquid Chromatography. Unfortunately the most undesirable feature of drugs containing the DHP (dihydropyridine) group is high sensitivity to light .Such drugs are regarded as photo labile. Therefore the photo stability testing has become an important

/50 Lab 9 Report Template: Acid Catalyzed Dehydration of 2-Methylcyclohexanol Abstract In Experiment 9‚ distillation was used to carry out the dehydration of 2-methylcyclohexanol using 4:1 mixture of phosphoric and sulfuric acid. Gas Chromatography was then used to measure the products. Two products were formed. The theoretical yield of the alkene mixture was 3.914 g. The actual yield of the mixture was 0.73 g. The percent yield for the reaction was 18.65%. Peak A had an area of 0.3 mm2

Information and Research 1. Paper chromatography is used to break down colors with using water and the way the colors separate. 2. Doctors can use it to test for alcohol in people’s blood. People can also use it to check for pollutants in the water. Pharmacists can use it to find out how much of each chemical is in each product. 3. I searched it up on google. Purpose The purpose of this test is to see what colors are in certain colors. We use chromatography to separate them/ Materials
