“…Unlike zabuyelite, Na and K-carbonates have high solubility, which for K-carbonate increases with elevated temperature. 54 The absence of these minerals in the precipitated phases is consistent with the expected higher thermodynamic stability of zabuyelite with respect to these phase. 55 As Na + and K + will not compete directly for carbonate via the growth of additional solid phases, the main influence of these ions will be on the chemistry of the system.…”

Lithium-bearing brines are an increasingly attractive source of Li for extraction. One extraction mechanism is the removal of Li from the fluid phase through the precipitation of zabuyelite (Li2CO3). The chemistry of the brine plays an important role in this process because ions in solution can compete for the components of the Li-carbonate phase. Here we explore the effect of different brine components on the precipitation of zabuyelite using experiments and computational simulations. Crystals formed in all solutions showed morphological evidence for potential transformation from a precursor phase. Our study indicates that Ca2+ and SO42– are incorporated into the precipitated zabuyelite crystals. Sulfate also interacts directly with specific surfaces on the growing crystal and is expected to form ion pairs with Li+ in solution. Similarly, Na+ appears to form ion pairs in solution with the carbonate ion, slowing nucleation of zabuyelite in the experiments. K+ and Cl– may interact with the growing zabuyelite crystals but do not appear to affect zabuyelite nucleation and growth times. These experiments highlight the importance of understanding the solution chemistry on zabuyelite formation in order to predict the efficiency of extraction processes and the purity of the solids.

“…Although the data described in Table indicate that the performances of K 2 HPO 4 and K 2 CO 3 were much weaker than those of K 4 P 2 O 7 and K 3 PO 4 , the separation of 1‐propanol using K 2 HPO 4 and K 2 CO 3 was satisfying due to their high solubilities . The correlation between the solubility of 1‐propanol and the molality of salt in Fig.…”

BACKGROUND: Today there is a resurgence of interest in using short-chain hydrophilic alcohols and salts to recover stronger polar bio-based chemicals and fuels for use as platform chemicals and renewable alternative transportation fuels. How to reduce the extractant depletion during the recovery of other bio-based chemicals from the fermentation broths is a problem of concern to researchers. RESULTS:The present work investigated a 1-propanol salt aqueous two-phase system and its application to recover bio-based acetoin. The water + 1-propanol + K 4 P 2 O 7 system was preferred for recovering bio-based acetoin according to the recovery of 1-propanol in the 1-propanol salt aqueous two-phase ternary system and after extraction of acetoin, and the salt content in the organic phase so as to avoid the losses of salt and 1-propanol.CONCLUSION: Subsequently, almost 100% of acetoin can be recovered from the aqueous solution; almost all of the salt was retained in the aqueous phase and more than 99% of 1-propanol was recovered.
