Abstract

Gluconic acid and its salts have a wide application in many branches of industry, medicine and pharmacy. Calcium-gluconate can be obtained by gluconic acid reaction with suitable calcium compounds. The applied method was of obtaining calcium-gluconate by electrolysis aqueous glucose solution in the presence of KBr and CaCO3., while obtained gluconic acid in the reaction with calcium-carbonate gives calcium-gluconate. It is proven that by applying an electrochemical process and subsequent procedure of purification, calcium-carbonate monohydrate can be obtained, without bromides additives. It is also proven that ethanol, being used in the process, can be recycled and used again, making the process more economical and ecologically advanced. Based on research results, block diagram of pilot-plant process of obtaining calcium-gluconate monohydrate was suggested.
