More than five decades of experience in hydrocyanic acid (HCN) production

Evonik is a worldwide leader in hydrocyanic acid production technology.

We have vast expertise and substantial know-how in three of the four direct synthesis processes that are used industrially to produce hydrocyanic acid: 

• the Andrussow process, which is most widely used
• the BMA process
• the formamide process. 

We have already granted licenses for these processes to reputed companies such as Akzo Nobel.
