Abstract: The invention relates to a process for the production of an infusion or dialysis solution containing bicarbonate and having a physiologically tolerable pH. In order to retain a solution with a stable physiologically tolerable pH even after heat treatment for sterilization, according to the invention, at least 2 mmol/L of at least one carboxylic acid ester is introduced into the solution beforehand. The solution is subjected to heat treatment above 100.degree. C., so that the carboxylic acid ester decomposes almost completely into carboxylic acid and alcohol. The invention further relates to a use of the process according to the invention for the production of a solution for peritoneal dialysis and a medicinal infusion or dialysis solution.
