13 Crotonaldehyde Uses: Facts You Should Know!

by

Crotonaldehyde is chemical compound with chemical formulae CH3CH=CHCHO, generally found as mixture of E and Z isomers. Let us explore some facts below:

  • Crotonaldehyde is highly reactive intermediates in many reactions with partially soluble nature in organic solvents.
  • Crotonaldehyde like solvent Because of its ability to enter into a variety of reactions due to its aldehyde function and the conjugated olefinic double bond inside the aldehyde, crotonaldehyde is a crucial starting material for chemical synthesis.
  • Crotonaldehyde forms azeotrope mixture with water at certain temperature and pressure.

Crotonaldehyde is used for industrial, pharmaceuticals, agricultural purposes and for many chemical reactions. In this article, we will learn, varied functions and important role of crotonaldehyde

In aspect of agricultural uses

Crotonaldehyde, which is produced through aldol condensation from acetaldehyde, is a nearly colourless liquid that ranges in colour from white to pale yellow, is extremely combustible, and has a strong aroma.

  • Crotonaldehyde is a raw material for crop protection in the agricultural sector.
  • Crotonaldehyde is also used as a warming agent in fuel gases and as a solvent in organic synthesis.
  • Crotonaldehyde can be used as slow-release fertilizers when combined with urea.

As food supplement’s

Crotonaldehyde is precursor of sorbic acid, is a class of substances that can prevent, delay, or stop the deterioration of food caused by fermentation, acidification, or other processes.

  • Crotonaldehyde inhibits the growth of Mould and yeast, acts as a fungistatic agent.
  • Crotonaldehyde serves as a preservative for cosmetics.
  • Crotonaldehyde is also used to dry oils, in alkyd-type coatings, to prevent Moulds from fermenting, to impregnate polyethylene wrappers for raw agricultural products.
  • Crotonaldehyde enhances animal feed growth stimulation.

Industrial uses

Crotonaldehyde is a versatile chemical with a wide range of reactivity. It is a prochiral dienophile because of its special stereo characteristic.

  • Crotonaldehyde has been utilized as a leather tanning agent, a denaturant, a warning agent in fuel gases, a rubber accelerator, a stabilizer for tetraethyl-lead, and a warning agent in fuel gases.
  • In polymer chemistry, with Crotonaldehyde it is possible to produce resins and polyvinyl acetals, as well as rubber antioxidants and ketones, which boost rubber strength.
  • Helps in production of sorbic acid, maleic acid, crotonic acid, butyraldehyde and methoxy butyraldehyde.

Conclusions

Crotonaldehyde can be made by condensation of aldol, which is produced when acetaldehyde interacts with weak NaOH. When an aldol molecule is heated, either on its own or in conjunction with I2, have various uses from food supplements to agricultural and industrial aspect as well.
