摘要
The reversible reactive extraction of long-chain terpenyl amines (TPAs) using organic acids as reactive extractants was investigated. The scope of suitable acids has been extended and semicontinuous and continuous experiments were performed to prove the applicability of this concept. High extraction yields could be achieved using a variety of acids in batch and semicontinuous experiments. Furthermore, the recovery and separation of the extracted TPAs from the extractant phase has been studied. The TPAs can be recovered in high yields and purities by simple means of process parameter changes. The proposed process allows the separation and purification of TPAs in high yields and purities without the creation of salts or other chemical by-products.
