BTEC APPLIED SCIENCE Unit 4 learning aim C 2022/2023 UNIT 4 AIM C PREPARATION OF ASPIRIN USING TECHNIQUE AND TESTING METHOD INTODUCTION In this unit, we will be using techniques and testing methods to prepare and test for aspirin. It is also called acetylsalicylic. The aim of this unit is to accurately prepare, test the purity and describe using methods of how aspirin (the organic solid) is made in the industry. The organic solid (aspirin) is a medicine used to bring down fever, inflammation and reduced pain. It is normally used as normal painkillers such as toothaches, headaches and to cure common cold symptoms. After the preparation of the organic solid we will test the purity and compare it to laboratory and industrial process of their preparation of aspirin. To prepare the organic solid (aspirin), we use salicylic acid (acetylation with acetic anhydride). To prepare and test the purity, we are going to have a two parts experiments. Apparatus for part one of the experiment we are going to need,  10cm3 measuring cylinder  Sulfuric acid (concentrated)  Spatula  Deionized or distilled water  Thermometer  250 cm3 beaker  Filter paper  Filtration apparatus to reduce pressure
