PENTAERYTHRITOL DERIVATIVES AND A PROCESS FOR PREPARING THE SAME

摘要

Complexes of pentaerythritol derivatives such as sulfuric acid ester of pentaerythritol or dipentaerythritol with a basic polyaluminum chloride and process for preparing the same are disclosed. The complex is novel and has a good anti-pepsin activity and therefore it is useful as an anti-ulcer agent. The complex is prepared by reacting pentaerythritol or dipentaerythritol with a sulfating agent and then reacting the resulting sulfate with a basic polyaluminum chloride.
