Solvent Exposure and Toxic Responses
Published in Stephen K. Hall, Joana Chakraborty, Randall J. Ruch, Chemical Exposure and Toxic Responses, 2020
Alcohols are hydrocarbons substituted with a single hydroxyl group. They are widely used as cleaning agents, thinners, and diluents; as vehicles for paints, pesticides, and pharmaceuticals; as extracting agents; and as chemical intermediates. Methyl alcohol is widely used as an industrial solvent and as an adulterant to denature ethanol to prevent its abuse when used as an industrial solvent. Another important industrial use of methyl alcohol is in the production of formaldehyde. Isopropyl alcohol is used as rubbing alcohol and in the manufacture of acetone. Cyclohexanol is used to produce adipic acid for the production of nylon. In general, the aliphatic alcohols with more than five carbon atoms are divided into the plasticizer range (6 to 11 carbons) and the detergent range (>12 carbons).
Fluid–Fluid Dispersions: Liquid–Liquid and Gas–Liquid Systems
Published in Wioletta Podgórska, Multiphase Particulate Systems in Turbulent Flows, 2019
One of the most common gas–liquid reactions is hydrogenation. It is common not only in the chemical industry, but also in the fat industry to produce margarine, frying oils, and shortenings. An important gas–liquid reaction that is widely used in chemical industries all over the world is cyclohexane oxidation. The desired products are cyclohexanone and cyclohexanol, which are used to produce caprolactam, adipic acid, and subsequently polyamide fibers, and plastics such as nylon 6 and nylon 66. One of the most commonly applied industrial methods of cyclohexane oxidation is the CYCLOPOL process, in which cyclohexane is oxidized by air or a mixture of O2/air in a flow reactor divided into chambers, to which air is introduced through spargers (Krzysztoforski et al., 1986; Pohorecki et al., 2001a,b, 2009).

The selective oxidation of hydrocarbons involving the activation of C-C, C-H bonds and/or the concomitant formation of C-OH or C = O bonds to produce more suitable products (for fine chemical synthesis) is a must [1]. Cyclohexane oxidation products (cyclohexanol and cyclohexanone) are important reagents for the production of caprolactam, adipic acid and monomers to prepare nylon-6 and nylon-6,6 polymers. Currently, the industrial processes for cyclohexane oxidation on using cobalt salts or metal–boric acid with molecular oxygen as an oxidant have some inherent drawbacks (lower conversion and selectivity, expensive investment) and cause serious pollutions [2].
