Abstract
A method for producing a solution of ammonium carbamate is provided. The method comprises reacting ammonium hydroxide with sodium bicarbonate. The method avoids the complications of using carbon dioxide and can be carried out using standard equipment. The resulting solution of ammonium carbamate can be used to form a biocide by mixing with a hypochlorite oxidant.
