Abstract

DC60 (15/06/55) A method for producing arginine bicarbonate is provided, including reacting the arginine slurry with a source of carbon dioxide under high temperature and low pressure to form a solution of at least 50% arginine bicarbonate, and recovering the arginine bicarbonate from the solution. A method for producing arginine bicarbonate is provided, including reacting the arginine slurry with a source of carbon dioxide under high temperature and low pressure to form a solution of at least 50% arginine bicarbonate, and recovering the arginine bicarbonate from the solution.

Claims (1)

1. A method for producing arginine bicarbonate, comprising: contacting carbon dioxide gas at a pressure of 6895 Pa(1 psi) to 68947 Pa(10 psi) with a starting slurry containing arginine at a temperature of 60 C to 80 C to form a slurry or solution including arginine and bicarbonate anion; contacting the slurry or solution with carbon dioxide until the slurry or solution is a low pH solution.
