associated theoretical value due to the overall percent yield, which will be discussed further. Also, according to the same calculations made in calculation #1, the calculated mass for Bayer Aspirin was inaccurate as the calculated value was less than what was said by the company. In other words, the Bayer Aspirin did not contain 325mg of ASA, instead it actually contained 283mg. The percent purity of ASA was calculated to be 65.0 % and based on the reaction table, the limiting reagent was salicylic
CHARACTERISTICS OF ASPIRIN- ACETYLSALCYLIC ACID Summary: The lab experiment was divided into parts and the synthesis of the aspirin occurred during the first week. Using 4.032g of salicylic acid 8.0mL of acetic anhydride on a hot bath the reaction was speeded up by the use of a catalyst phosphoric acid. Once the sample was then left to dry in the drawer for a week using the melting point apparatus we conducted the purity assessment of the dried sample. Introduction: Aspirin (acetylsalicylic acid)
The over the counter medication once known only for its ability of easing aches and pains or fighting off fever and inflammation is proving itself to be quite the miracle drug. Aspirin has become part of the protocol for stroke victims as a preventative measure due to its neuro-protective benefits. Stroke can cause lesions in cerebral white matter, which may result in cognitive impairments such as deficits in learning and memory. White matter lesions (WML) have also been linked to increasing the
Positivism or more specifically, logical positivism, is “maintained that science is value free, independent of the scientist, and obtained using objective methods” (McEwen & Wills, 2007, p.8). This leads to no biased interpretation of the data. In summary, objectivity and facts are the basis of received view. Perceived view can be seen as the opposite of received view. In perceived view, also known as interpretive views, phenomenology and constructivism are two major characteristics. Phenomenology
Trial of Low-Dose Aspirin in the Primary Prevention of Cardiovascular Disease in Women,” is a generally well-articulated article describing the large randomized trial of nearly 40,000 women and the impact of low dose aspirin followed for 10 years on the end-point of cardiovascular events. The authors present a compelling case for investigating the use of aspirin in women specifically citing a lack of data in the literature, and more specifically the differences in metabolism of aspirin by women and the
Executive Summary The single most rewarding opportunity faced by the company is how to position Datril to the general public in 1975 and gain substantial and sustainable market share in the analgesics market. This situation is an opportunity because Bristol-Myers needed to figure out how to successfully price and promote Datril as it launched in the analgesics market. Two main options are available (1) whether to promote Datril as a direct point of sale towards the consumer or (2) to adopt the
Synthesis and Characterization of Aspirin Product Identity and Purity After synthesizing a chemical, especially a drug, it is important to confirm the identity and purity of the product. You will perform three tests to examine the identity and purity of the aspirin that you synthesized. One test will detect the presence of leftover salicylic acid in the synthesized aspirin and allow you to determine its concentration. Government regulations stipulate that commercial aspirin must not contain residual
Experiment 1: Release of Aspirin from a Polymer Matrix Summary Firstly, aspirin was weigh to 0.25g which was then dissolved in 100cm3 of distilled water by heating to >80°C using a hotplate. 2.0g of agar was added while stirring and was heated till dispersed, giving almost clear solution. The temperature was control so as not to overheat the agar. The agar was left to cool in an ice bath. Using a hollow cylinder, the agar was cut to approximately 4.0g (the exact weight of the agar was recorded).
Non-ST Elevation Myocardial Infarction There are three different types of an acute coronary syndrome. There is unstable angina, a non-ST elevation myocardial infarction (NSTEMI), and there is a ST elevation myocardial infarction (STEMI). A STEMI and NSTEMI are both deciphered as a myocardial infarction, or better known as a heart attack. The difference between the two is that a STEMI is a fully blocked coronary artery, and a NSTEMI is a partially blocked one. “A heart attack occurs when the blood
I’ve been hired as a Program Coordinator at Women's Heart Center at the Bakersfield Heart Hospital who has been ask to research the social and behavioral aspects of Cardiovascular Disease in Women and make recommendations about changes in social and behavioral factors that will lead to a decrease in this public health issue. The Women's Heart Center at the Bakersfield Heart Hospital is devoted to screening and educating women on understanding in decreasing their risk of cardiovascular disease.
