Title: Separating the components of “Panacetin” Name: Ip‚ Wing Chung (Vincent) Lab Partner: Ma‚ Siyin Date: 2/3/2013 Introduction: The purpose of this experiment is to investigate the composition of compounds in Panacetin. Generally‚ it is made up of sucrose‚ aspirin and an unknown component‚ either acetanilide or phenacetin. SinceBy using different techniques‚ such as filtration‚ extraction‚ and evaporation‚ those three components have been isolated out‚ which is based on varies solubility

Separating the Components of Panacetin: Introduction: Of the three components likely to be present in your sample of Panacetin (aspirin‚ acetanilide‚ and starch)‚ only starch is insoluble in the organic solvent dichloromethane (or methylene chloride)‚ CH2 Cl2. If a sample of Panacetin is dissolved as completely as possible in dichloromethane‚ the insoluble starch can be filtered out‚ leaving acetanilide and aspirin in solution. The purpose of this experiment is to extract the components of Panacetin

Separating The Components of “Panacetin” Observations Most natural products and many commercial preparations are mixtures containing a number of different substances. To obtain a pure compound from such a mixture‚ you must separate the desired compound from the other components of the mixture by taking advantage of differences in their physical and chemical properties. Acidic or basic substances are often converted to water-soluble salts‚ which can then be separated from the water-insoluble

Dictionary of Quantitative Methods in Management. Sage Publications Principal Components Analysis Introduction Principal Components Analysis (PCA) attempts to analyse the structure in a data set in order to define uncorrelated components that capture the variation in the data. The identification of components is often desirable as it is usually easier to consider a relatively small number of unrelated components which have been derived from the data than a larger group of related variables. PCA
