Abstract Acetic Anhydride and p-Aminophenol were heated in a vial attached to an air condenser to synthesize crude acetaminophen‚ resulting in 0.097 grams (47.48% yield). The crude acetaminophen was then recrystallized in a solvent of water and methanol over heat resulting in 0.082 grams (39.61% yield) of pure acetaminophen. Melting points of both crude and pure acetaminophen were taken‚ and found to be 165.9 - 170.9°C and 168.2 - 171.5°C‚ respectively. The literature melting point of acetaminophen

Aspartame “Diet Coke does not contain nasty chemicals. It contains lovely and delicious carbonation‚ caffeine‚ and aspartame. What’s unnatural about that?” Meg Cabot. This chapter was based on Power and Wealth. The article that I did my paper was about Aspartame. These two subjects connect because the individuals who drink the Diet Coke are getting fooled by the big companies that are selling it to them. The power elite are selling false hopes and false products‚ so people will buy their inventory

Title: Nitration of Methyl Benzoate Objective: To prepare methyl-3-nitrobenzene from nitration of methyl benzoate. Results and calculations: Density = 1.094 g/ml = Mass of methyl benzoate = 1.094 g/ml x 2.8 ml = 3.0632 g no. of mol of methyl benzoate = = 0.022499 mol 1 mol of methyl benzoate produced 1 mol of methyl m-nitrobenzene. Therefore‚ 0.022499 mol of methyl benzoate produced 0.022499 mol of methl

In order to carry out a detailed stability study of OXP and CYPZ in combination‚ it is essential to have a single stability-indicating assay method which can separate both drugs along with all of their degradation products from each other. Therefore‚ a RP-HPLC method was developed and optimized. Optimization of the chromatographic conditions In this study‚ the different experimental parameters were carefully studied and optimized in order to improve the performance and system suitability parameters

Louis Pascual Relao De La Salle University- Dasmariñas Dasmariñas Cavite Philippines ABSTRACT The Copper Reactions experiment was demonstrate by adding the reagents like 16M HNO3‚ Distilled water‚ 6M NaOH‚ 6M H2SO4‚ Acetone‚ Zinc metal and Methanol into the beaker with the copper wire. The experiment was also demonstrated to observe how copper reacts while different reagent were being added. It was also demonstrated to practice the common laboratory techniques such as method of separation involving

3.8.1.2 Leaf area and leaf area index (LAI) Leaf area of five randomly selected plants‚ was measured with the help of leaf area meter (Model LI-3100‚ USA) at 20‚ 40 and 60 DAS by destructive sampling from all leaves of the five sample plants (Sticker et al.‚ 1961). Plants were cut at the soil surface‚ leaves were separated from the plants‚ covered with blotting paper to keep the leaf intact and retain its original shape and were brought to the laboratory. Leaf area was measured immediately after

In addition‚ 21 species collected from different Jordanian localities including A. palaestinum are evaluated for their antioxidant activity and showed that the DPPH-TEAC of the methanol extract of the studied taxa were varied from 4.1 to 365.0 mg/g dw versus 0.6 to 267.0 mg g-1 in aqueous extracts and A. palaestinum leaves gave moderate activity (DPPH-TEAC range 20-80 mg g-1) and showed that the potential rule in radical scavenging
