Date: April 23‚ 2012 Subject: Preparation of Synthetic Banana oil Summary: Banana Oil is a major flavoring in many different mixtures from candles to different types of food. The major organic chemical that is banana oil is ester‚ which is what gives it its strong odor. In this scenario‚ the banana oil supply is running low for Cavendish Distilling Company. So they want to formulate a synthetic version of banana oil to replenish their supply. Problem: Will the synthetic version of banana oil

I. Results Started with : 40mL acetic acid 4.005g PHPB 2.00g trans-stilbene 1.54g KOH 13mL methanol 21mL ethylene glycerol 2.726g stibene dibromide produced Actual yield : 0.818g diphenlacetylene Melting Point : 62 - 75 degrees Celsius II. Discussion The experimental melting point range of our purified product was 60 degrees Celsius when researched‚ but when done experimentally was only. This began around the right range‚ but ended up being much higher than the literature value

3.1 Overview The experiment was divided into three parts. In the first part was the preparation of empty CNPs. The second part was the preparation of CNPs loaded with single drug which was AA and TQ meanwhile the third part was the preparation of CNPs loaded with dual drug (AA and TQ). The last part was the analytical testing conducted to investigate the properties performance such as smaller or larger in trend as well as to characterize the entrapment efficiency of drugs. The chemicals and technique

Godly aspect Psalm 63: Prayer is the breath of our relationship of God. The absence of prayer shows that we are spiritually dead. I don’t mean just saying prayers that are not spawned from the heart‚ of course. Jesus said empty prayers amounted to only religious ceremony. One can dress up a dead body but there sure is a difference between that corpse and a living person even if he is sick. What do you think of when prayer is mentioned? This is a good question. Your answers reveal a lot about your

TITLE: Determination of Riboflavin by using UV-Vis spectrophotometry. ABSTRACT: The amount of Riboflavin in various brand of children multivitamins was determine by using UV-Vis spectroscopy instrument‚ the series of standard of riboflavin was prepared in order to determine the amount of the riboflavin in the sample of children multivitamins. The maximum amount of riboflavin was found in the Champs multivitamin that contains 0.1155 mg followed by Chewies 0.1131 mg and Scott’s 0.0672 mg. OBJECTIVES:

SUPPLEMENTARY MATERIAL I Unit V: States of Matter 5.7 KINETIC ENERGY AND MOLECULAR SPEEDS Molecules of gases remain in continuous motion. While moving they collide with each other and with the walls of the container. This results in change of their speed and redistribution of energy. So the speed and energy of all the molecules of the gas at any instant are not the same. Thus‚ we can obtain only average value of speed of molecules. If there are n number of molecules in a sample and their individual

contaminant we will focus on is grease or oil which is common in machines as a lubricant. The group will focus on using Sodium Bicarbonate or Baking Soda and Oyster. Both of these materials have proven to be effective stain removers with vinegar being 8% acetic acid diluted in water. The group plans on mixing the two ingredients to create a cleaning agent capable of removing grease or oil stains. It will be used for stains found in cloth. Sodium Bicarbonate is also used as a deodorant and can remove odours

GENERAL BIOCHEMISTRY Problem Set No. 1 Answered by: Andrea Rose A. Fajardo of BSFT 2-1N 1. Calculate the pH of a dilute solution that contains a molar ratio of potassium acetate to acetic acid (pKa=4.76) of: a. 2:1 pH = 4.76 + log[2]/[1] = 4.76 + 0.3010 = 5.06 b. 1:4 pH = 4.76 + log[1]/[4] = 4.76 + (-0.6021) = 4.16 c. 6:5 pH = 4.76 + log[6]/[5] = 4.76 + 0.0792
