Abstract
A process for synthesizing isooctyl nitrate in a continuous flow reactor comprises flowing a H2SO4-HNO3 mixture within a flow reactor, flowing isooctyl alcohol into said flow reactor so as to mix the isooctyl alcohol with the H2SO4-HNO3 mixture and produce a reaction mixture stream flowing in said reactor, maintaining the reaction mixture stream flowing in said flow reactor at a reaction temperature within in the range −10° to 35° C. inclusive, and wherein the residence time of the reaction mixture stream in the flow reactor is greater than or equal to 5 seconds and less than or equal to 40 seconds, and wherein the H2SO4 of the H2SO4-HNO3 mixture is H2SO4 having a concentration of in the range of 85 to 95% inclusive, more desirably 88 to 92% inclusive, most desirably of 90%.
