Azodicarboxamide is a chemical compound from the group of azo compounds, and urea derivatives.

Production and representation

Azodicarboxamide can be obtained by reaction of urea with hydrazine and oxidation of the resulting intermediate.

Properties

Azodicarbonamide is a yellowish solid. It decomposes above 90 ° C, with nitrogen, carbon monoxide, isocyanic acid and polymerization products thereof, as well as ammonia and develop a strong pressure rise takes place in closed vessels. During thermal degradation occurs semicarbazide.

Use

Azodicarboxamide is used as a leavening agent. Foods made ​​from flour is added as a dough improver azodicarbonamide. This use of azodicarbonamide in food is not allowed in the EU. Azodicarbonamide is often used in the plastics industry as a blowing agent to form the plastic parts.
