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.

Methods and compositions are provided for refining natural oils and for producing high-weight esters, high-weight acids, and/or high-weight derivatives thereof, wherein the compositions are made by cross-metathesizing low-weight unsaturated esters or low-weight unsaturated acids having hydrocarbon chain lengths less than or equal to C24 with an olefin feedstock, thereby forming a metathesized product composition including high-weight esters or high-weight acids having hydrocarbon chain lengths greater than C18, wherein at least a portion of the hydrocarbon chain lengths in the metathesized product are larger than the hydrocarbon chain lengths in the starting feedstock.

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.
