Manual for Recrystallization essays Chapter 1 Equipment involved and preparation Chapter 2 Setup procedure before purification Chapter 3 Gathering of an unknown compound and the first step: filtration Collection and measuring of crude sample Chapter 5 Evaluation methods for purity Chapter 6 Frequently asked Questions and trouble shooting To begin, the intent of this booklet is to give instructional advice. The instructions given will provide a basis to allow an individual to perform the necessary task to undergo the purification process. The design of the manual is to instruct students in a college laboratory setting. In particular, the area of science that the manual will focus on is Organic Chemistry. Students will be able to refer to this instruction guide throughout the semester because this process will be put in use often. The purification process if an essential part of chemistry, and the student must recognize its importance. Without a purified product, many of the drugs on the market would not be on sale. Even though these purification procedures are on a small scale, it will provide a starting point for those who are just beginning Organic Chemistry. The skills needed to purify a product will come with practice and help from the instructor, but this manual will give the initial directions to help t he student on purification. Once mastered, more techniques will help the student to gain a product that is pure enough to put on the market. The Equipment involved and preparation The first step in understanding any laboratory process is understanding the equipment needed. Also, there is a need for the proper preparation of the tools needed before any of the steps can begin. The main pieces of glassware needed to conduct the filtration and recrystallization will be at least two 250ml flasks, a 100ml flask, and at least three 50 ml flasks. In addition, a glass stirring rod and a case of micropipettes would be useful. For the filtration...
