PROCESS FOR MAKING NITRILES |
摘要 |
<p>Adiponitrile is made by reacting 3-pentenenitrile with hydrogen cyanide. The 3-pentenenitrile is made by reacting 1,3-butadiene with hydrogen cyanide. The catalyst for the reaction of 1,3-butadiene with hydrogen cyanide to make 3-pentenenitrile is recycled. At least a portion of the recycled catalyst is purified by an extraction process, which separates catalyst degradation products and reaction byproduct from the catalyst.</p> |
