Abstract PCT No. PCT/JP80/00186 Sec. 371 Date Apr. 27, 1981 Sec. 102(e) Date Apr. 14, 1981 PCT Filed Aug. 20, 1980 PCT Pub. No. WO81/00515 PCT Pub. Date Mar. 5, 1981.A process for preparing a composition having low hygroscopicity, in the form of uniform particles and useful for perfusing artificial kidney systems from compounds to give an electrolyte ion composition comprising Na+, K+, Ca++, Mg++, C1- and CH3COO- ions in specified proportions, the process being characterized by dissolving the compounds in warm water, allowing the solution to stand for at least 6 hours and thereafter spray-drying the resulting aqueous solution of mixed salts by spraying the solution into a drying chamber having an inlet temperature of 200 DEG to 400 DEG C. from the orifice of a pressurized nozzle having an orifice diameter of 1.0 to 2.0 mm.
A process for preparing a composition having low hygroscopicity, in the form of uniform particles and useful for perfusing artificial kidney systems from compounds to give an electrolyte ion composition comprising 126-145 mEq/l of Na + , 1.5--3.0 mEq/l of K + , 2.5-4.0 mEq/l of Ca ++ , 1.0-1.5 mEq/l of Mg ++ , 98-108 mEq/l of Cl - and 30-4.52 mEq/l of CH 3 COO - , said process comprising dissolving the compounds in warm water having a temperature of about 35° to 40° C., allowing the solution to stand for at least 6 hours, and thereafter spray-drying the resulting aqueous solution of mixed salts by spraying the solution into a drying chamber having an inlet temperature of 200° to 400° C. from the orifice of a spray nozzle having an orifice diameter of 1.0 to 2.0 mm to form said composition.
