摘要： Methods and systems for treating an aqueous effluent from a metathesis reactor, such as a metathesis-based biorefinery, are generally disclosed. In some embodiments, the aqueous effluent is generated from washing the metathesized product with an aqueous medium. In some embodiments, such wash streams are chemically treated to reduce their toxicity and to facilitate disposal. In some embodiments, such wash streams are treated to recover at least a portion of the catalyst residue, so as to facilitate catalyst recovery.

摘要： High-purity dibasic acid compositions are generally disclosed. In some embodiments, the dibasic acid compositions are solutions or suspensions. In some other embodiments, the compositions are solid-state compositions. In some such embodiments, the solid-state compositions include a dibasic acid as a crystalline solid and further include a low quantity of certain impurities, such as monobasic acids, various esters, and the like. Methods and systems for making such high-purity dibasic acid compositions are also disclosed.
