Despite its toxicity, Crotonaldehyde remains an important industrial chemical. It is used in a variety of applications and is an important intermediate in the production of other chemicals. However, the potential health risks associated with its use must be carefully considered and managed to ensure that workers and the environment are protected. Crotonaldehyde is typically produced by the aldol condensation of acetaldehyde. In this process, acetaldehyde is reacted with a base to form an enolate ion. The enolate ion then reacts with another molecule of acetaldehyde to form crotonaldehyde. Another method for producing crotonaldehyde is by the dehydration of glycerol. Glycerol is reacted with an acid catalyst to form acrolein, which is then hydrogenated to form crotonaldehyde.
