Chapter 38-Organic Liquids
Pages: 9 Published: Jan 2005
ORGANIC LIQUIDS ARE USED in a wide variety of industrial applications. They can be characterized as liquids that consist of one or more carbon atoms joined to other atoms via covalent bonds. Common atoms included in organic molecules are hydrogen, oxygen, nitrogen, sulfur, and halogens. Both the rate and yield of certain reactions have been found to greatly increase when performed in organic liquids. Thus, they are widely used in the chemical process industry for synthesis. With the increase in the use of organic liquids, increases in observed corrosion problems associated with the exposure of materials to them have also occurred. In some cases, failures involve an unacceptably large loss of metal or degradation of material properties. However, in many other cases, the major issue is discoloration or degradation of the organic solution resulting from corrosion of the processing vessel, as the solution is the product of commercial interest. For example, many Pharmaceuticals are synthesized in organic solutions in large vessels. For these applications, the corrosion resistance requirements for materials used are stringent. The introduction of metals into a product can lead to rapid degradation of the product, as well as health and safety concerns.
