Benzoic acid

have some hazardous drawbacks. The only hazard of working with p-anisaldehyde is the danger involved if swallowed (4-Methoxybenz-aldehyde). This compound is not combustible. Some hazards of working with benzoic acid are irritation to the nasal cavity and eyes if fumes come in contact (Benzoic acid). This compound is combustible. Some hazards of working with Ethanol are eye and skin irritation and causes organ toxicity (Ethanol). This compound is combustible. Some hazards of working with Potassium

m-aminobenzoic acid stored away which is currently not being used for anything. This reactant can be used in certain reactions to produce valuable solutions for ophthalmologists. This product is going to waste, and our objective is to see if we can obtain a usable end product when

Salicylic Acid Testing Observations - The indicator that showed the presence of Salicylic Acid in the aspirin was the change in color from white to dark purple. The color that indicated the lack of Salicylic Acid was light yellow. Conclusion The weight of crude aspirin obtained from 4g of Salicylic Acid was 4.74g. After recrystallization, approximately 2.9g of recrystallized aspirin was obtained. After calculating the molar mass of Salicylic Acid and aspirin, the theoretically obtainable weight

Alfred Lee 01/31/2015 TA: Zhixun Wang Friday 5:00PM Discussion – Experiment 3A: Separation and Identification of Organic Unknowns Unknown #1 Extraction is a separation method that utilizes differences in solubility to separate compounds (1). The purpose of this experiment was to separate three different organic compounds using extraction and then to identify them by using infrared (IR) spectroscopy. An extraction was carried out on a 750-mg

Acid Base Extraction The purpose of this laboratory assignment was two-fold, first, we were to demonstrate the extraction of acids and bases, finally, determining what unknowns were present. Second, we were to extract caffeine from tea. These two assignment will be documented in two separate entities. Introduction: Acid/base extraction involves carrying out simple acid/base reactions in order to separate strong organic acids, weak organic acids neutral organic compounds and basic organic substances

Goal: The goal of the recrystallization laboratory is to purify chemicals by dissolving their impurities. Both acetanilide and benzoic acid will be utilized as our impure solids. By adding small quantities of solvents such as ethanol and water, we will be able to isolate the impurities and extract them from the solution. What is left will be a solution pure enough to form solid precipitates (crystals). The crystals will be isolated using a Buchner funnel and vacuum filtration. Significance: One

hydrogen in the compound's carboxyl group is replaced with a hydrocarbon group. Esters are derived from carboxylic acids and (usually) an alcohol (Helmensine A, 2017). The reaction required to produce an ester is called esterification. Esterification is the reaction in which a Carboxylic acid combines with an alcohol in the presence of a catalyst (commonly concentrated sulphuric acid) to form an ester (Esterification, 2017). This is an example of a general class of reactions called condensations

first experiment was done on a compound which is commonly known as a triglyceride which contains three fatty acids and a glycerol backbone. The next experiment was done one a caffeine which is a hetercylic ring. However, this heterocyclic ring has all oxygens in the place of the carbons. The third eextraction was done on benzoic acid and acentanilide and the last experiment was done on acetic acid to purify an ester. The first of these many experiments was the extraction of trimyristin from nutmeg. Trimyristin

Module 01 Homework Assignment Use the information presented in this module along with additional outside research to answer the questions: 1. Describe how applied microbiology is used to improve aspects of life and the environment. Microbiology is the study of microorganisms (VanMeter, VanMeter, & Hubert, n.d., p.3). These are all of the things not visible to the human eye. With the study of microbiology, it enables us to find things such as viruses and bacteria. This is helpful because

1. Soccer is one of the most demanding of all sports. The game is played on one of the largest fields of any sport, for the longest sustained time and with the least amount of breaks. Players in a soccer team are in continuous activity as they compete for loose balls, move to encourage teammates, rotate positions and run to make a space or test opponents. Running, jumping, sprinting movements in relation with sudden changes of acceleration and route outweigh the play. The power of the game ranges
