Wang Experiment #4 Recrystallization of Pure Phthalic Acid‚ Benzoic Acid and Napthalene Introduction Recrystallization is a important method in purifying organic compounds which are solid. It is an effective method that is important to be familiar with that is essential in the industrial chemical world. This experiment will allow students to be familiarized with the technique of recrystallization by working with phtalic acid‚ benzoic acid and naphthalene from appropriate organic solvents.

Quality of Palmstearin Liquid Oil Blends and Hydrogenated Fat (vanaspati) S. Ray and D.K. Bhattacharyya* Department of Chemical Technology‚ University Colleges of Science and Technology‚ Calcutta University‚ Calcutta - 700 009‚ India ABSTRACT: An attempt was made to use high-melting lowdigestible fat palmstearin as a vanaspati substitute by blending it with polyunsaturated fatty acid-rich liquid oils. This blending produced fat products of zero-trans fatty acid content and melting points below

During protein digestion‚ a water molecule is added which breaks down the carbonyl-carbon-nitrogen sin the peptide bonds of proteins causing the liberation of amino acids. This process is referred to as proteolysis. Water molecules break down the carbonyl-carbon-nitrogen single bond (peptide bond) that holds single amino acid molecules together (Caroline Ritchie‚ 2013. This process is called hydrolysis and is catalysed by protease. The three main protease enzymes produced during digestion are pepsin

4/27/11 SYNTHESIS AND CHEMILUMINESCENCE OF LUMINOL Abstract: Chemiluminescence occurs in nature and can be found in everyday products. For example‚ the light omitted by fireflies‚ deep sea fish and glow sticks is a result of this process. Luminol was synthesized from from 3-nitrophthalic acid and then combined with potassium ferricyanide and hydrogen peroxide to omit a blue light. The product of this reaction is very unstable and is made by losing a nitrogen and the electrons go from an excited

Claims:What is claimed is: 1. A method of producing an organic fertilizer by using fish‚ said method comprising the steps of preparing a raw material containing more than 80% of fish heads‚ boiling the raw material to obtain a stock‚ removing solids and oil contents from the stock to obtain stock liquid‚ thereafter treating the stock liquid in a decomposition tank with decomposing enzyme for enzyme decomposition‚ filtering the enzyme-decomposed stock liquid to produce a clarified liquid organic fertilizer

Measurement in Fats and Oils. Introduction : Vegetable oil is an important and widely used lipid source for our everyday food products. Its application is increasing day by day for food purposes and for the manufacturing of a number of toiletry products. However‚ some vegetable oils are not up to standards to meet consumer satisfaction in terms of their physico-chemical properties or for the texture and stability of the food products (Reyes- Hernandez et al.‚ 2007). Recently‚ palm oil has become the

SYNTHESIS OF AN ALKYL HALIDE S.M. BLANCAFLOR1 1INSTITUTE OF BIOLOGY‚ COLLEGE OF SCIENCE UNIVERSITY OF THE PHILIPPINES‚ DILIMAN‚ QUEZON CITY 1101‚ PHILIPPINES DATE SUBMITTED: 3 JANUARY 2012 DATE PERFORMED: 8 DECEMBER 2011 ------------------------------------------------- ABSTRACT Alkyl halides are molecules which have a carbon atom attached to a halogen atom (e.g.‚ chlorine‚ iodine‚ or bromine.) Alkyl halides are very important since they are used in many of the products used today

Prelab 5B Macrocyclic Synthesis OBJECTIVE: The objective this week is to produce Tetraphenylporphyrin and its metal complex. This will be carried out by condensation of 4 equivalents of Benzaldehyde and pyyrole in the presence of propanoic acid. The product will undergo UV/Visible Spectrum tests to determine its lambda max. The lambda max will show us the relationship between a conjugated system and the visible spectrum. PROCEDURE: Step 1: preparation of meso-tetraphenylporphyrin (TPP)
