Abstract:
1. Method for the continuous production of a plasma diluent or dialysis solutions based on hydrolytically broken down starch derivatives that are optionally substituted, by hydrolyzing with a hydrolysis agent in an aqueous medium and subsequent neutralization to stop the hydrolysis, the method comprising: a main hydrolysis wherein an aqueous solution that contains the starch or optionally substituted starch to be hydrolyzed is continuously conveyed through at least one reactor essentially free of mixing against the force of gravity in the hydrolysis step at a flow rate of about 5 to 20 cm/min; and a fine hydrolysis, wherein the fine hydrolysis is carried out after the main hydrolysis, a roughly hydrolyzed starch solution being fed to a tubular reactor with mixing elements at a preset temperature during said fine hydrolysis.
