Process for making a cyclodextrin |
| abstract |
Sulfoalkyl ether cyclodextrins are produced by a process of treating annunsubstituted cyclodextrin starting material with an alkyl sultone in the presence of anbase. The base is added in a stepwise, pH controlled manner so that substantiallynthe entire initial charge of cyclodextrin starting material is at least partially reacted.nAdditional base is then added to complete the reaction, and residual alkyl sultone isndestroyed. The product advantageously contains low levels of both residualncyclodextrin and residual alkyl sultone. |
