6. RESULTS AND DISCUSSION All the results generated from the present study are represented in the respective tables. The powdered gum of Acacia arabica was subjected to preliminary organoleptic evaluation. The scanty availability of information on this plant facilitates the study on it. The attempt is made to study the Pharmacognostical, phytochemical and pharmacological activities of gum of the plant. The study was divided into three major parts viz. • Pharmacognostical studies •…

The electrochemical properties of the squaraine dyes (SQ1 & SQ2) were investigated. The effects of the chemical structures of two SQ1&SQ2 dyes were selected in relation to the variable property of -COOH substituent for SQ1 compare to SQ2 which without substituent and determine their potential energy levels in ground and excited states HOMO and LUMO. The HOMO energy levels of the SQ1 & SQ2 dyes are -5.19 eV and -5.16 eV. The LUMO energy levels are calculated to be -3.08 eV and -3.1eV respectively…

PHYSICAL PROPERTIES: It has two isomeric forms 1, 2, 3-triazole and 1,2,4-triazol with common molecular formula C2H3N3,and both have 69.06 molecular weight. [2]] 1, 2, 4-triazole derivatives simply exist in solid forms. 3, 4, 5-substituted 1, 2, 4-triazole derivatives melts on thermolysis when heated at high temperature3160C for half an hour. 1, 2, 4-Triazole derivatives are easily soluble in polar solvents and slightly soluble in non-polar solvents. However the solubility in non-polar solvents…

Experiment 5 Synthesis and NMR Spectroscopy of ethyl cinnamate Introduction: Wittig reactions involve the stereoselective synthesis of olefins from phosphonium ylides and aldehydes or ketones, where the carbonyl bond is converted to an alkene double bond.1 The variety of suitable reagents and the relatively mild experimental conditions facilitate their industrial applications, such as the synthesis of epoxides, esters, carotenoids and vitamin A.2,3 Specifically, the ester ethyl cinnamate is used…

Introduction Spinach is a leafy green plant that is high in vitamins. Spinach gains its green color from the pigments it contains which help the plant absorb sunlight needed for photosynthesis. The main pigments are chlorophyll a, chlorophyll b, and β-carotene. Chlorophyll presents as a green pigment and is a porphyrin while β-carotene is a red-orange pigment and a carotenoid. [1] They are both found in all pants and are sensitive to exposure to light and air. β-carotene has been used in the…

The MTBE operation consists of various units; the focal units are De Iso Butanizer (DIB), Butamer, Oleflex and Ethermax. Methanol produced from QAFAC, mixed butane from QP NGL facilities and water with power from KAHRAMAA and small amounts of chemicals to be used such as: 10% Caustic, DMDS, PERC and Chlorine are the required raw materials needed to generate MTBE. Producing MTBE starts with passing the Butane mixture that is in the storage sphere at QAFAC through the DIB unit where the…

Ali Youssef CHM 111-0A7L Mitra Jahangeri Paper Chromatography Lab Discussion The results of the Paper Chromatography process seem to have aligned with what was expected. When the capillary action on the paper had completed and the chromatograph was finished, the distance that each cation moved (D), as well as the distance that the solvent moved (L), could be properly measured. The distance that the solvent moved ended up being 7.05cm, a number that would represent the constant variable L in…

reaction of propylene oxide and water. This involve the process of the hydrolysis of propylene oxide (C3H6O, PO) with the presence of excess water and a small concentration of catalyst. The catalyst that plays the role in this reaction is the sulphuric acid. The reaction occurs in the reactor at the reasonable rate which near the ambient temperatures. The temperature of the solution can rises due to the continuous reaction process. The heat reaction because of the temperature of propylene…

Slime is made by mixing together borax, glue, and water. Depending on the amount of borax added to the mixture will determine the density of the slime. For our experiment in class the independent variable was the borax. The dependent variable was slime. The control group was glue. It was important to keep the amount of glue, borax, and water constant throughout the experiment. In an experiment conducted in class it was hypothesized that the more borax added the denser the slime will be.…
