Preparation of Esters Introduction Esters are known for their pleasant smells such as perfumes and artificial flavorings in contained labs. They are formed when a carboxylic acid reacts with alcohol and a strong acid such as a catalyst called sulfuric acid (H2SO4) for this lab. The structural formula for esters can be represented as R-COO-R’. The R and R’ symbolizes different alkyl groups that can be combined to the ester. When naming an ester the first part comes from the alcohol followed

Chromic acid was used in this experiment to in order to prepare 2-butanol. Cr (VI) is rather orange‚ but Cr (III) is dark green - therefore by oxidizing the alcohol (2-butanol)‚ an orange Cr (IV) is reduced to green. NMR and IR tests were taken to determine the result‚ and the crystallized derivative of

PREPARATION OF ALUMINA POWDERS 1. BAYERS PROCESS INTRODUCTION The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. DEFINITION The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). The aluminium oxide must be purified before it
