Ethanol fermentation

RESULTS SOLUBILITY ANALYSIS: Ketoprofen sample was found to be soluble in ethanol, Chloroform, ether, acetone at neutral pH and is found to be almost insoluble in water. Solubility analysis is important because the drug has to dissolve in the solvents and also in the dissolution medium used. MELTING POINT DETERMINATION: The melting point of the Ketoprofen was found to be 96˚C by open capillary tube using microcontroller based melting point apparatus which is within the reported range of 94˚C…

After deprotonation of 6.8 mmol naphthalen-2-ol by 14.0 mmol NaOH, the resulting anion was placed together with 8.8 mmol 1-iodobutane, and the reaction was performed by reflux in 20 mL of ethanol (EtOH) solvent, and the product was allowed to cool on ice and collected by suction filtration. The final crystals had a very pale amber color and were odorless. The following week, after being allowed to completely dry for a week at room temperature, the IR spectrum of the product in liquid suspension…

volumetric flask and 50 ml methanol was added to it and shakes for few minutes to prepare 1000microgram/ml. Stock solution From this solution the stock solution was prepared by taking 1 ml from standard solution and made the volume to 100 by ethanol and then prepare the solution of 0-10 µg/ml and check the absorbance at 330 nm in UV spectrum. Absorbance v/s concentration were plotted to obtain the calibration graph. The drugs obeyed beer’s law with the above concentration range with ‘r’…

1. Abstract In this study, reverse micellar extraction of asparaginase model system was carried out using CTAB/Iso-octane/hexanol/butanol system to optimize the forward and back extraction efficiency. By using Taguchi’s orthogonal array (OA), maximum forward extraction efficiency of 55.0%, 61.0% and 54% was achieved with an aqueous phase pH of 11.0, 150mM CTAB/Iso-octane and 0.1 M NaCl, respectively. Similarly, Taguchi’s orthogonal array (OA) was applied to optimize the pH of stripping phase,…

CHAPTER 5 PROPERTIES OF MAHUA METHYL ESTER AND THEIR BLENDS WITH DIESEL 5.1 INTRODUCTION In this work, characteristic fuel properties of mixture of Mahua methyl ester and their blends with diesel in the proportions of 10:90, 25:75, 50:50, 75:25 and 100:0 respectively were studied. The characteristics fuel properties of Mahua methyl ester blends were found to be those of diesel oil. 5.2 MATERIAL AND METHODS The Mahua oil methyl ester was prepared by using three stage transesterification…

Adsorption isotherm models : To study the proper model, the isotherm data were analyzed and were fitted them into two models, Freundlich and Langmuir, because they are the most suitable and employed models. Equilibrium uptake of CV and MB was investigated with sorbent weight of 0.5 g of fennel seeds in contact with 100 mL of solutions and at pH 4 for CV and 6 for MB. The flasks were shaken at 200 rpm and the equilibrium concentration of the remaining CV and MB was determined by spectrometer.…

TLC and HPTLC Introductions Thin layer chromatography (TLC) is derived from liquid chromatography where liquid serves as mobile phase and thin layer of substance on a flat late surface serves as stationary phase. The thin layer of materials act as sorbent while the mobile phase known as solvent. Solvent will send the solutes through the sorbent depends on the strength of the mobile phase as it dissolved the solute and send them up the plate against gravity ,and resistance of sorbent…

The 1HNMR of chloro (pyridine) cobaloxime (III) showed all the characteristic peaks of the product. It had very few peaks and is very tidy. This shows that the molecule has high symmetry. The large singlet peak at 2.5ppm, corresponds to the 4 methyl groups that are connected to the double bond N of the dimethylglyoxime. It integrates to 12 H’s. These methyl groups are accounted for at a higher ppm that usual. This could be due to the fact they are doubly bonded to the electronegative Nitrogen…

Preformulation Study Preparation of calibration curve of Amoxicillin trihydrate [51,53,76] Preparation of stock for Hydrochloric acid Stock solution in 0.1N Hydrochloric acid (0.1N HCl): 10 mg of Amoxicillin was accurately weighed and transferred into 10 ml volumetric flask. It was dissolved and diluted to volume make up to mark with 0.1N HCl to give stock solution containing 1000 µg/ml, after than 1ml take to from 1000 µg/ml and dilute to volume make up to mark of 10ml volumetric flask with…

In the health risk assessment, my highest scores were avoiding chemical dependency, personal safety, and emotional well-being. Avoiding chemical dependency is one of my highest scored topics because I do not drink, or do drugs. I am a firm believer that taking drugs, and drinking underage, will ruin your life, so I stay far away from them. Some ways that I stay away from drugs and drinking is that I do not go to parties. A lot of students come to college for the social scene and the partying. I…
