The purpose of this investigation was to determine which type of alcohol (ethanol‚ butan-1-ol‚ or propan-2-ol) contains the most energy per gram. It was expected that if we burn three alcohols (ethanol‚ propan-2-ol‚ and butan-1-ol) for 2 minutes‚ then butan-1-ol will release the most energy per gram (J/g) because butan-1-ol contains more carbon atoms than other alcohols which means more energy is required to break its chemical bonds and more energy will be released when new chemical bonds are formed

in the presence of weak base. However‚ for RH-PY‚ the stearic hindrance of pyrene slows the reactivity‚ and the reaction does not go to completion. Therefore‚ the reaction procedure was modified as follows. First‚ HATU and DIPEA were used to activate the carboxyl group of rhodamine B‚ then the activated rhodamine B was reacted with 1-aminopyrene. By introducing this method‚ the reaction completed‚ affording the target product in high yield (70%). The structure of RH-PY was analyzed by 1H-NMR and ESI-TOF

AND OIL DEFINITION: Fats and oils‚ group of organic substances that form an important part of the diet and also are useful in many industries. The fats are usually solid‚ the oils generally liquid at ordinary room temperatures. Some tropical products‚ liquids in their sites of origin‚ become solids in cooler climates; in commerce these often retain the name originally given‚ e.g.‚ palm oil and coconut oil. Chemically fats and oils are either simple or mixed glyceryl esters of organic acids belonging

Acetylsalicylic Acid Experiment 01/25/2013 CHM Lab- 2211 Sec 0016 Instructor: Jennifer Reed Introduction: Commonly used as Aspirin‚ acetylsalicylic acid is an analgesic (pain reliever)‚ which is one of the products of the esterification reaction between salicylic acid and acetic anhydride. This esterification occurs since the hydroxyl group from the salicylic acid reacts with acetic anhydride to form an ester. In this experiment‚ we will be able to recreate this acid catalyzed reaction‚ using

Jennifer Everett Phase 4 DB Instructor: Clement Yedjou 3/10/2015 Acid rain Acid rain is a result of air pollution that is harmful to the environment‚ generally caused by fuels being burnt. When any type of fuel is burnt‚ many different chemicals are produced. These gases that are released react with the water in clouds‚ and the rain from these clouds is acid rain. This type of acid disposition can appear in many other forms besides just rain‚ such as sleet‚ snow‚ and fog (Editorial Board‚ 2013)

Manufacturing of Sunflower Oil Refined sunflower oil will be ready to consume after two manufacturing processes. They are raw oil manufacturing and refining processes. These two steps are charted below. Chart-I: Manufacturing of Raw Oil Chart-II: Manufacturing of Refined Oil Raw oil manufacturing consists of 2 stages. These are pressing and extraction stages. In the first stage‚ seed of sunflower becomes sunflower oil. Cleaning‚ breaking‚ separation‚ shimming‚ roasting and pressing processes

Acid Rain and the Effects of our Monuments and Churches The two controlled experiments that I chose to do‚ do not involve trees or plants‚ which I think a lot of people will be doing. I wanted to explore the devastation that acid rain does to our historic monuments and beautiful churches. My first controlled experiment is based on the Statue of Liberty. It is made of copper so I am using pennies in my experiment. (nps.gov. n.d.) My observation is that acid rain corrodes metals

coconut oil due to its high levels of saturated fat. Advocacy against coconut and palm oils in the 1970s and 80s due to their perceived danger as a saturated fat caused companies to instead substitute trans fats‚ unaware of their health-damaging effects.[28] Coconut oil contains a large proportion of lauric acid‚ a saturated fat that raises blood cholesterol levels by increasing the amount of high-density lipoprotein (HDL) cholesterol[29] that is also found in significant amounts in laurel oil‚ palm

Acetylsalicylic Acid September 15‚ 2005 September 23‚ 2005 OBJECTIVES The objective of this lab experiment is to prepare aspirin (acetylsalicylic acid) by reacting salicylic acid and acetic anhydride. INTRODUCTION This purpose of this lab was to prepare aspirin using its basic components: salicylic acid and acetic anhydride. Salicylic acid and acetic anhydride‚ along with an acid catalyst‚ react to form acetylsalicylic acid (aspirin) and acetic acid. In this reaction‚ the hydroxyl group
