Melting point of crude acetaminophen
A cause and effect outline is a tool used to organize and structure a written argument or discussion that focuses on the reasons why something happened and the consequences that resulted from it. It is a common structure used in academic writing, particularly in the fields of history, social sciences, and natural sciences.
There are many ways to organize a cause and effect outline, but one common method is to use a series of nested headings and subheadings to represent the different levels of causation and effect. For example, the main heading might be "The Causes of the American Revolution," and the subheadings might be "Economic Factors," "Political Factors," and "Ideological Factors." Under each of these subheadings, you would then list the specific causes that contributed to the event in question.
Another way to organize a cause and effect outline is to use a chronological approach, in which the causes are listed in the order in which they occurred and the effects are listed in the order in which they resulted. This method is often used when discussing events that took place over a period of time, such as the development of a new technology or the spread of a disease.
A third method is to use a "chain of causation" approach, in which each cause leads directly to the next effect, creating a linear chain of events. This method is often used when discussing complex systems or processes that involve multiple interconnected causes and effects.
Regardless of the approach you choose, it is important to make sure that your cause and effect outline is clear, logical, and well-organized. It should clearly identify the main causes and effects of the event or phenomenon you are discussing, and it should be structured in a way that makes it easy for readers to follow and understand.
Here are a few examples of cause and effect outlines using different organizational approaches:
I. The Causes of the American Revolution
A. Economic Factors
1. High taxes on imported goods
2. Restrictions on trade
B. Political Factors
1. Lack of representation in Parliament
2. Infringement on colonial rights
C. Ideological Factors
1. Enlightenment ideas of liberty and democracy
2. Influence of the French Revolution
I. The Development of the Internet
A. 1950s: Research on packet-switching technology
B. 1960s: ARPANET and the first computer networks
C. 1970s: Wide-area networks and the development of TCP/IP
D. 1980s: The proliferation of personal computers and the rise of the World Wide Web
E. 1990s: The commercialization of the Internet and the explosion of online business
F. 2000s: The rise of social media and the growth of the "digital economy"
I. The Spread of the COVID-19 Pandemic
A. Cause: SARS-CoV-2 virus emerges in Wuhan, China
B. Effect: COVID-19 cases begin to appear in Wuhan
C. Cause: COVID-19 spreads beyond Wuhan through international travel
D. Effect: COVID-19 cases appear in other countries
E. Cause: COVID-19 spreads within countries through local transmission
F. Effect: COVID-19 cases increase in multiple countries
G. Cause: Governments implement measures to slow the spread of COVID-19
H. Effect: COVID-19 cases begin to decrease in some countries
The melting point analysis of crude and recrystallized acetaminophen synthesized essay sample
All of the solid was allowed to fade out. The hypothesis was tested by dropping ten of each of the forms of the acetaminophen into two thirds a cup of boiling water and observing how much each had dissolved after ten minutes. These properties, including solubility, stability, intrinsic dissolution and bioavailability, affect the extent to which the body can utilize the drug effectively, and it is thus vital that drugs are developed to Separating the Components of Panacetin some of these drugs can reduce both illnesses. Once recrystallization has occured, comparison by melting point confirms the purification. . It was so placed into an ice bath for 10 proceedingss until crystallisation was complete. Then we use Hβ molecular sieve as catalyst and acetone as the solvent to obtain acetaminophen by rearrangement and the yield is 81.
The Melting Point Analysis of Crude and Recrystallized Acetaminophen Synthesized
The melting point of the product confirmed the high level of purity, and the difference between the crude and recrystallized products could be easily observed. Acetic Anhydride and p-Aminophenol were heated in a vial attached to an air condenser to synthesize crude acetaminophen, resulting in 0. Cooling the mixture in an ice bath ensures that all crystals have formed, and drying removes any remaining solvent. Hepatic necrosis and inflammation develop as a consequence of hepatocellular death, which results in development of clinical and laboratory findings consistent with liver failure. The runing point of the petroleum Datril 165. The color grades gradually from pink to brown then to black, so it should be sealed and stored in a cool and dry place.
Melting Point Analysis Of Acetaminophen
The melting point range of crude acetaminophen ranged from 166. The purpose of this experiment was to find out which of the three tested forms of acetaminophen would dissolve the most over a time period ten minutes. The crystals were weighed and a small sample was placed into a capillary tube for melting point determination. When heating the salicylic acid mixture in the warm water bath, the mixture should be removed from the bath within 8 minutes, to reduce the chance of the acetylsalicylic acid decomposing. P-acetaminophen is synthesized acetylation by one-step acylation without separation and the yield is 64. Melting points of both crude and pure acetaminophen were taken, and found to be 165. The crude product is purified by addition of NaOH to solubilize it filtration to remove impurities, and then the product is reprecipitated by addition of HCl.
Acetaminophen: Crystal and Crude Product
Once recrystallization has occured, comparison by melting point confirms the purification. The crystals were then placed on a watch glass for further drying. The active ingredients of Excedrin were caffeine, acetaminophen, and aspirin with Rf values of 0. It is used for cold and toothache. A spin vane was placed into the vial and an air condenser was attached. Set up the Craig tube apparatus described in technique 11, section11.
After decolorization process, 0. Paracetamol is metabolised by hepatic microsomal enzymes mainly to the glucuronide, sulphate and cysteine conjugates. Overall, however, the experiment was successful, as pure acetaminophen was synthesized. In this experiment it is prepared by the reaction of p-aminophenol with acetic anhydride, as illustrated below. It is in the transferring process of p-aminophenol to a 5mL conical vial.
why is the melting point of crude acetaminophen similar to the purified acetaminophen?
Melting points were taken for both the crude 165. An automatic pipet was used to mensurate 0. The vial was cooled to room temperature then placed in an ice bath for 15 minutes. However, its action is weaker than aspirin and it is only effective for mild to moderate pain. Many proposed that acetaminophen works by inhibiting the variant COX cyclooxygenase enzymes that are metabolized to produce prostaglandins, enzymes that cause the pain. The Craig tube was plugged and set in an Erlenmeyer flask to cool. In one plate, five known samples were used as the reference, that is: Aspirin; Caffeine; Ibuprofen; and Salicylamide.
The Melting Point Analysis Of Crude And Recrystallized Acetaminophen Synthesized, Sample of Essays
After conducting a TLC plate, the Rf value was calculated to be. The melting point of the crude acetaminophen 165. Defervescence treatment is generally less than 3 days and the administration of pain relief lasts less than 10 days. Results of the Ferric Chloride test showed that no unreacted salicylic acid present. Fit the test tube with a cork stopper and take it back to your hood. Pharmacological Actions Acetaminophen is used as antipyretic analgesics. In addition, it also can be used for the synthesis of benorylate and used as asymmetric synthetic intermediates, photographic chemicals and stabilizer of hydrogen peroxide.
Crude Acetaminophen Synthesis
Panacetin is typically made up of sucrose, aspirin, and acetaminophen, but the third component in this experiment is unknown. Using phenol as raw material Phenol is used as the raw material and synthesizes paracetamol after acetylation, Fries rearrangement, oxime and Beckmann rearrangement. Phosphoric acid was used as a catalyst in the synthesis to speed up the process. So it is necessary to adjust the dosage of anticoagulant drugs. Usage Organic synthesis intermediates, stabilizer of hydrogen peroxide, photographic chemicals, non anti-inflammatory analgesia-antipyretic drugs. Some of both merchandises could hold been lost when transferred to the ticker glass to be weighed.
