Abstract
A process for the production of nitrosyl fluoride from nitrite and hydrogen fluoride. Nitrite solids and hydrogen fluoride are separately introduced and blended into nitrosyl fluoride so as to form a reaction mixture within which the nitrite and the hydrogen fluoride react to produce additional nitrosyl fluoride. The hydrogen fluoride is introduced into the reaction mixture spaced away from where the nitrite is introduced into the reaction mixture so that the hydrogen fluoride and the nitrite separately mix into the nitrosyl fluoride and are diluted therein before mixing with each other, thereby avoiding a violent reaction between the hydrogen fluoride and the nitrite.
Claims12
A process for the preparation of nitrosyl fluoride, comprising separately introducing and blending nitrite and hydrogen fluoride into nitrosyl fluoride solution so as to form a reaction mixture within which the nitrite and the hydrogen fluoride react so as to produce additional nitrosyl fluoride, wherein said hydrogen fluoride is introduced into said reaction mixture spaced away from where said nitrite is introduced into said reaction mixture so that the hydrogen fluoride and the nitrite independently mix into said nitrosyl fluoride solution and are diluted therein before mixing with each other, thereby avoiding a violent reaction between the hydrogen fluoride and the nitrite.
A process for the preparation of nitrosyl fluoride, comprising continuously and separately introducing and blending nitrite and hydrogen fluoride into nitrosyl fluoride solution so as to form a reaction mixture within which the nitrite and the hydrogen fluoride react to produce additional nitrosyl fluoride, and periodically removing nitrosyl fluoride produced in the reaction mixture, wherein said hydrogen fluoride is introduced into said reaction mixture spaced away from where said nitrite is introduced into said reaction mixture so that the hydrogen fluoride and the nitrite independently mix into said nitrosyl fluoride and are diluted therein before mixing with each other, thereby avoiding a violent reaction between the hydrogen fluoride and the nitrite.
