Synthesis of Phenols You can prepare phenols in large quantities by the pyrolysis of the sodium salt of benzene sulfonic acid‚ by the Dow process‚ and by the air oxidation of cumene. Each of these processes is described below. You can also prepare small amounts of phenol by the peroxide oxidation of phenylboronic acid and the hydrolysis of diazonium salts. Pyrolysis of sodium benzene sulfonate In this process‚ benzene sulfonic acid is reacted with aqueous sodium hydroxide. The resulting salt

Matrix Management ____________________________________________________________________ We typically see it as the leader’s responsibility to get the best out of his or her people – but how do organisational structures help or hinder performance? In the better‚ cheaper‚ faster world of the global economy anything that creates bottlenecks and slows up decision-making is an obstacle to success. In this respect hierarchical management and functional silos are bad news; what employers want to drive

Technological crises[edit] Technological crises are caused by human application of science and technology. Technological accidents inevitably occur when technology becomes complex and coupled and something goes wrong in the system as a whole (Technological breakdowns). Some technological crises occur when human error causes disruptions (Human breakdowns[7]). People tend to assign blame for a technological disaster because technology is subject to human manipulation whereas they do not hold anyone

Title: Thin-Layer Chromatography Objectives: Part1: 1. To learn the technique of TLC and the visualization of colourless components. 2. To identify an unknown drug by a TLC comparison with standard compounds. Part 2: To learn the separation technique by using Thin Layer Chromatography plate in separating a mixture of compounds into individual pure compound by using Spinach Leaf. Introduction: (i) General Concepts Chromatography is a common and powerful method used to separate and analyze complex

TLC can also be of aid in identifying unknown compounds. Separation of compounds is achieved as a partitioning occurs between a mobile phase and a stationary phase. In TLC‚ the stationary phase is composed of a thin layer of the highly polar silica gel that is deposited on a glass or plastic plate‚ and the mobile phase consists of a liquid solvent that runs up the plate through capillary action‚ carrying the solutes‚ or the chemical compounds that are to be separated and analyzed. The principles of
