Title:
CYCLODEXTRAIN POLYMER AND PRODUCTION OF CYCLODEXTRIN MEMBRANE
Document Type and Number:
Japanese Patent JPH0425505
Kind Code:
A
Abstract:
PURPOSE:To obtain a cyclodextrin membrane having excellent film strengths and specific separating capacity, permeability, etc., by reacting a cellulose derivative with cyclodextrin (derivative) and forming the obtained cyclodextrin into membrane. CONSTITUTION:A cellulose derivative (e.g. an acid chloride of carboxymethylcellulose) is reacted with cyclodextrin (derivative) to produce a cyclodextrin polymer. The obtained polymer is formed into membrane by, for example, dissolving it in a solvent, casting the solution over a support and removing the solvent. In this way, a cyclodextrin membrane containing cyclodextrin in a high rate can be produced, and the obtained membrane can be used without the necessity for using another supporting film and can withstand continuous operation.
