The types of experiments that may take place in colleges and schools around the world‚ differ in many aspects to experiments that although produce the same end product‚ are done on a much larger scale in industry. The aspects they may differ in are equipment‚ time taken‚ and many other things. In this report I will explain how and why laboratory and industrial scale differ using the example of preparation of aspirin. The first difference is that instead of weighing the 2-hydroxybenzoic acid on scales

experiment involved the separation of the unknown from the Panacetin by first isolating the sucrose and the aspirin. This process was done by starting with three grams of Panacetin and adding dichloromethane to dissolve and then separating the sucrose by filter-gravity filtration. The aspirin was then separated with the help of sodium hydroxide to isolate the unknown. From the values found‚ we were able to find percentages of sucrose‚ aspirin‚ and the unknown in relation to what is found on the labels of

markers and filter paper and our choices may have affected our results. For example‚ we had the choice between a coffee filter and a circular piece of filter paper. We originally chose the coffee filter but we thought the creases in our paper would distort our results. After finally deciding on the circular paper and cutting it into a rectangle‚ I placed it in the beaker to see if it fit properly. Unfortunately‚ I did not notice that the beaker had water in it and had soaked the edge of the filter paper
