A method for the production of carbamate compounds comprises the steps of: A) reacting an organic primary amine with an organic halogen compound in the presence of a quaternary organic ammonium carbonate and/or bicarbonate, thereby obtaining a reaction mixture comprising a carbamate compound and a quaternary organic ammonium salt; B) separating the quaternary organic ammonium salt from the reaction mixture obtained after step A); C) contacting the quaternary organic ammonium salt obtained after step B) with a carbonate and/or bicarbonate anion-exchange resin, thereby obtaining a quaternary organic ammonium carbonate and/or bicarbonate; D) repeating step A) at least once, wherein the quaternary organic ammonium carbonate and/or bicarbonate employed in this next step A) is at least partially sourced from the quaternary organic ammonium carbonate and/or bicarbonate obtained from the preceding step C).
