the purified aspirin product was 5.77%. Next a phenol test was performed on the crude aspirin product‚ the purified aspirin product‚ and salicylic acid as a control. The phenol test was to test the purity of the aspirin product that was created during the experiment. The crude aspirin product and the purified aspirin product had no color changes and remained orange when mixed with the iron (III) chloride solution‚ which means that there were no phenol groups in both the crude aspirin product and the

heat of reaction depends on the nature of weak electrolyte and can be either exothermic or endothermic. Thus measurement of heat of reaction will permit to differentiate between strong and weak electrolytes. In this experiment‚ a weak electrolyte‚ phenol is used‚ and the change in enthalpy is endothermic‚ ΔH=q=25.3kJ/mol. The first part of this experiment involves the neutralization of strong electrolytes. 40 mL of 2.0 M HCL was used to neutralized 50 mL of 2.0 M NaOH. Both the solutions were mixed

Synthesis of Aspirin and Oil of Wintergreen Janelle Alyssa P. Prudente De La Salle University-Dasmariñas Dasmariñas City‚ Cavite‚ Philippines ABSTRACT In this experiment‚ acetylsalicylic acid commonly known as aspirin and methyl salicylate‚ commonly known as oil of wintergreen‚ was synthesized from salicylic acid. This study will show that it is possible to show two very different organic compounds from the same common starting material. For the synthesis of aspirin‚ salicylic acid

current study‚ we carried out a comparative analysis of the antioxidant activities of extracts of the selected leaves of 6 common medicinal plants. Total Ascorbic Acid Content‚ Total Carotenoid Content‚ Antioxidant potential using FRAP assay and Total Phenol Content was quantitatively estimated from leaves of Rauvolfia serpentina‚ Cymbopogon citrates‚ Hibiscus rosa sinensis‚ Zingiber officinale‚ Calotropis procera and Spinacia oleracea. It was found in this study that the highest total ascorbic acid content

claim to kill 99.9 percent of bacteria. Lysol contains Phenol which is a highly volatile organic compound. Phenol is a carbolic acid found in some household cleaning supplies. Phenol is very toxic and because of this it is designed to kill bacteria. The phenol within the Lysol causes the environment where the bacteria thrive to be uninhabitable. Pinesol has several other organic compounds in it as well but none as volatile as Phenol‚ yet some consumers say that Pinesol is just as useful
