PREPARATION OF ASPIRIN AND DETERMINATION OF THE MELTING POINT Ferrer‚ Lara Melissa V. Faculty of Engineering University of Santo Tomas Manila‚ Philippines ABSTRACT This experiment involved three steps: synthesis of aspirin‚ isolation and purification‚ and the estimation of purity of the final product. The synthesis involved the reaction of salicylic acid and acetic anhydride in the presence of a catalyst‚ phosphoric acid‚ H3PO4. When the aspirin was prepared‚ it was isolated and filtered. The percentage

September 30‚ 2012 Experiment 5‚ Preparation of Synthetic Banana Oil Introduction: This experiment prepares synthetic banana oil (isopentyl acetate) through the Fisher esterification method by combining isopentyl alcohol with acetic and sulfuric acid then heating the mixture under reflux for an hour. Esterification is a chemical reaction in which two reactants (an alcohol and an acid) form an ester as the reaction product. Observations and Data: When the sulfuric acid was combined

that were added from the burette is 0.00327 moles (1 tablet of Gaviscon). However‚ for Quick-eze‚ the number of moles is 0.00216 moles (1 tablet). This means the average volume of the NaOH have affected the number of moles as the concentration of the sodium hydroxide is 0.1M. This means that if less NaOH was required to neutralise the acid‚ the number of moles of HCl neutralized by the ant-acid would be greater. For example; by using mole ratio‚ the number of moles of HCl reacted with the NaOH is 0.00216

PREPARATION OF POTASH ALUM FROM SCRAP ALUMINUM Introduction Aluminium because of its low density‚ high tensile strength and resistance and resistance to corrosion is widely used for the manufacture of aeroplanes‚ automobiles lawn furniture as well as for aluminium cans. Being good conductor of electricity it is used for transmission of electricity. Aluminium is also used for making utensils. The recycling of aluminium cans and other aluminium products is a very positive contribution to saving

Steps in the data preparation process. Editing involves reviewing questionnaires to increase accuracy and precision. It consists of screening questionnaires to identify illegible‚ incomplete‚ inconsistent‚ or ambiguous responses. Responses may be illegible if they have been poorly recorded‚ such as answers to unstructured or open-ended questions. Likewise‚ questionnaires may be incomplete to varying degrees. A few or many questions may be unanswered. At this stage‚ the researcher makes a preliminary

The purpose of this study was to observe the effect of different concentrations of sodium chloride have on the germination of lettuce seeds‚ Lactuca sativa. A study done by Katembe et al.‚ (1998) stated that an increase in salt solution in the environment of the seed will slow down water imbibition‚ therefore‚ preventing germination and
