Production of water-soluble chitin oligomers by partial hydrolysis of chitin.

摘要

TETRA-N-Acetyl-CHITOTETRAOSA, PENTO-N-Acetyl-CHITOPENTOSA and hexa-N-acetyl-CHITOHEXAOSA, WHICH ARE chitin-oligomers IN WATER SOLUBLE MUST BE OBTAINED BY IMPROVED PRODUCTS, IF chitin Finely ground is rapidly and intimately mixed with a concentrated acid HIDROALOGENICO CONTAINING A PREPARATION OF Halide HYDROGEN PARTICULAR per unit mass chitin under irradiation with ultrasonic waves and also under agitation for mechanical stirrer, following Hydrolyzed chitin in the mixture resulting homogenous CONSTA chitin AND CONCENTRATE ACID hydrohalogenic, while said homogeneous mixture is also CONTINUOUSLY irradiated with the ultrasonic wave AND ALSO agitated by the mechanical stirrer. APPEARANCE hydrolyzing AQUEOUS REACTION MIXTURE recovering chitin OLIGONEM IN WATER SOLUBLE DESIRED, each immuno AS IS USEFUL, AGENT antitumor or antifungal, antibacterial agents.
