Paragraph 0011; 0023, (2020/06/02)
The organic metal salt additive, prepared by mixing :(1), washing, with short-chain organic acid as acid source, and then mixing, with the resulting solution of Step ;(2) to obtain the high-purity organic metal salt additive, has the advantages (1) as follows, The organic metal salt additive is relatively high in crystal form structure and high in purity, and has good industrial application prospects, through mixing, of an iron source or a calcium source, or a, zinc source with a high-purity, organic metal salt additive agent in an aqueous solution with, a wide,price. product source.

PROCESSES FOR PRODUCING NH4+ -OOC-R-COOH COMPOUNDS FROM FERMENTATION BROTHS CONTAINING NH4+ -OOC-R-COO-NH4+COMPOUNDS AND/OR HOOC-R-COOH COMPOUND ACIDS, AND CONVERSION OF NH4+ -OOC-R-COOH COMPOUNDS TO HOOC-R-COOH COMPOUND ACIDS

Page/Page column 31, (2011/11/13)
A process for making a NH4+ OOC-R-COOH compound from a clarified NH4+ OOC- R-COO' NH4+ compound-containing fermentation broth includes (a) distilling the broth to form an overhead that includes water and ammonia, and a liquid bottoms that includes a NH4+ OOC~R~COOH compound, at least some of a NH4+ QOC-R-COO" NH4+ compound, and at least about 20 wt% water; (b) cooling the bottoms to a temperature sufficient to cause the bottoms to separate into a NH4+ OOC-R~C00' NH4+ compound-containing liquid portion in contact with a NH4+ OOC-R-COOH compoond-containing solid portion that is substantially free of the NH4+ OOC-R-COO" NH4+compound; (c) separating the solid portion from the liquid portion; and (d) recovering the solid portion.
