Sialic acid powder and process for the preparation thereof |
| abstract |
An amorphous sialic acid powder is disclosed. It is prepared by rapidly freezing an aqueous solution of sialic acids and freeze-drying the frozen product. It has a melting point of 131 DEG -136 DEG C. (decomposed) and exhibits no peaks inherent to crystals in differential scanning thermal analysis (at 165 DEG -200 DEG C.) and X-ray diffractiometric pattern (in the range of 5 DEG </=2 theta </=40 DEG ). The amorphous sialic acid powder is highly reactive and can be used as a raw material for drugs and the like. |
