Preparation of starch sulfate esters |
摘要 |
Aqueous slurries or dispersions of starch are reacted with ammonium fluorosulfate or an alkali metal fluorosulfate to yield starch sulfate esters. The inorganic by-products produced in the reaction are readily removed by washing or dialysis. These starch products may also be prepared in non-aqueous solvents or by a dry reaction process.
