PROCESS FOR THE PRECIPITATION OF CYSTINE |
摘要 |
<p>A process for precipitating cystine from a solution in sulfuric acid, includes forming a mixture of a solution of cystine in aqueous sulfuric acid and of an aqueous solution of a base by simultaneous metering the cystine solution and the aqueous base solution into a mixing container. The metering takes place in such a way that the mixture in the container has a pH between 1.0 and 7.0 and a temperature between 30° C. and the boiling point of the mixture.</p> |
