Document Type and Number:
Japanese Patent JPH03153697
Kind Code:
A
Abstract:
NEW MATERIAL: Compounds of the formula [R' is H, acyl, alkyl; X is CH2OH, COOH, C(H)=NOH, CN, CH2NHR" (R" is H, acyl, aryl, alkyl, and others) and others] and their secondary products.
EXAMPLE: 5-(α-D-glucopyranosyloxymethyl)-furan-2-carboxaldehyde.
USE: Intermediate of production of surfactants.
PROCESS: A compound of the formula is obtained by dissolving anhydrous isomaltulose or isomaltulose hydrate in a high polar aprotic solvent in the isomaltulose/solvent ratio of 10-100 g/100 g, contacting this solution with an H+ type acidic ion exchanger as a catalyst at a temperature of 70-150°C, in the isomaltulose/ion exchanger ratio of 20/10-10/1, for 0.1-24 hours.
