experiment was to synthesize the Grignard reagent‚ phenyl magnesium bromide‚ and then use the manufactured Grignard reagent to synthesize the alcohol‚ triphenylmethanol‚ by reacting with benzophenone and protonation by H3O+. The triphenylmethanol was purified by recrystallization. The melting point‚ Infrared Spectroscopy‚ 13C NMR‚ and 1H NMR were used to characterize and confirm the recrystallized substance was triphenylmethanol. Introduction A Grignard reagent is a type of organometallic‚ which consists

oxidation. Sodium hypochlorite was used instead of the less “green” Jones reagent. Borneol was mixed with glacial acetic acid and oxidized with sodium hypochlorite to make crude camphor. The crude camphor was purified by sublimation. The final product was characterized by obtaining a melting point and inferred spectroscopy. The experiment was carried out to see if bleach could oxidize borneol and if it is greener than using a Jones reagent. Sure enough camphor was made with a 4.03 g of unsublimed camphor

Rule of Saint Benedict. “Listen carefully‚ my son‚ to the master’s instructions‚ and attend to them with the ear of your heart. This is advice from a father who loves you; welcome it‚ and faithfully put it into practice.” (St. Benedict‚ Prologue Page 1) With this rule as Benedict explains in his reading and in the presentation notes in class Benedict tells us the basis of his model of receptivity‚ reflectivity‚ and activity. (Model of Vocation Part. 1 page 3). For each word Benedict tells what

Composition of Cells Testing for Proteins: The independent variable is the biuret reagent. The dependent variable is the solutions being used as follows; distilled water‚ albumin solution‚ and starch solution. If the protein is present‚ then the biuret will change to a violet color. Authors: Eliza Koundry and Jody Cote Eliza was in charge of adding equal amounts of biuret reagent to the distilled water‚ albumin solution‚ and the starch solution. Jody was in charge of recording

SUBJECT: CLINICAL CHEMISTRY TITLE: TOTAL BILIRUBIN & DIRECT BILIRUBIN LABORATORY: 19 & 20 INTENDED USE: 1. For the quantitative determination of total bilirubin in serum 2. For the quantitative determination of direct bilirubin in serum INTRODUCTION: One part of bile is a yellow (or brownish) substance called bilirubin. Bilirubin starts out as a product of the breakdown of red blood cells. When red blood cells break down‚ the heme molecule is converted into bilirubin

The Sacraments of Initiation can be described as climbing a mountain. To climb‚ a person needs to be properly prepared‚ starting by being hydrated. Then‚ the person must climb‚ step by step‚ until he or she reaches the summit to enjoy the view. The hydration of the Sacraments of Initiation is Baptism; it’s the entrance into the Christian path. The gift of the Holy Spirit received during the Sacrament of Confirmation gives the strength needed to slowly‚ but surely make the journey. The summit that

Play Folio On the 22nd and 23rd of October 2012‚ our Theatre Performance will be performing our end of year showcase‚ Brontë: The life and the literature. The plays performed within the showcase will be Brontë and Jane Eyre. The two plays were chosen because Brontë explores the lives of the Brontë sisters and mentions their literally achievements and Jane Eyre‚ written by Charlotte Brontë (adapted by Polly Teale)‚ explores the struggle of a woman choosing between her head and heart‚ a pressure

Keywords acid value vegetable oils indirect titration A new method of acid value determination in vegetable oils has been developed. The method is based on (a) simple‚ rapid and complete extraction of acids from an oil test portion into reagent (0.05 mol dm–3 triethanolamine (B) in the mixture of 50 % H2O + 50 % 2-PrOH) and (b) indirect titration of acids in BH+ form against aqueous alkali in the presence of a phenolphthalein indicator. Suitable metrological parameters of acid value determination
