The Monsanto Investigation Part 1―the Bayer Investigation
Acetaldehyde is a possible cancer-causing compound that occurs naturally in alcoholic beverages and many foods such as bananas and yogurt. It may also be added to fruit-flavored foods. Acetaldehyde and benzaldehyde are used as solvents in air fresheners, but they also are easily volatilized at room temperature and pressure, and both have proven to be a health risk to humans through inhalation. Monsanto has a patent on the process for recovering acetaldehyde. The Wacker process or the Hoechst-Wacker process originally referred to the oxidation of ethylene to acetaldehyde by oxygen in water in the presence of a tetrachloropalladate catalyst. The same basic reaction is currently used to produce aldehydes and ketones from a number of alkenes with the Monsanto process for producing acetic acid.
