Ammonium succinate synthesis

3synthesis methods
A method of manufacturing a highly pure ammonium succinate solution including the steps of (A) producing calcium succinate trihydrate by crystallization fermentation of a microorganism; (B) converting calcium succinate trihydrate to calcium succinate monohydrate by transition crystallization; (C) separating the calcium succinate monohydrate crystals; (D) substituting the calcium salt in the calcium succinate monohydrate with ammonium salt resulting in an ammonium succinate solution; and (E) removing the solid calcium carbonate from the ammonium succinate solution.

Yield: 100%

Reaction Conditions:

with ammonium carbonate in water at 32 - 40; for 2 h;Product distribution / selectivity;Industry scale;

Steps:

4
EXAMPLE NO. 4; Synthesis of di-ammonium salt from succinic acid (S4H12N2O4).The synthesis is carried out in about in the same conditions as in example 3, however, instead of a freshly saturated solution of salt, a recycled (180 L) of filtrate is used, generating 148 kg of ammonium succinate with a content mass of 99.8%. Salt yield is 100%.
