Patent ID: 8497405

Claim:
A process for dispersing vaporous hydrogen peroxide using a decontaminant dispenser suitable for use as a projectile, wherein the dispenser comprises a container suitable for containing propellant grade liquid hydrogen peroxide, the container comprising a container wall with at least one opening in the container wall and a pressure release membrane positioned in the opening, the pressure release membrane being adapted to rupture when pressure within the container exceeds a predetermined value; and at least one catalytic probe adapted to be inserted into the container in contact with the liquid hydrogen peroxide, the catalytic probe being undersized so that when inserted into the container in contact with the hydrogen peroxide part of the hydrogen peroxide in the container reacts in an exothermic reaction to form a product composition, the product composition comprising water, oxygen, and unreacted hydrogen peroxide, the reaction being sufficient to generate an expansion of the product composition, the expansion being sufficient to rupture the pressure release membrane and drive the unreacted hydrogen peroxide through the at least one opening, the process comprising: filling the container with propellant grade hydrogen peroxide; and inserting the catalytic probe into the container in contact with the hydrogen peroxide to initiate an exothermic reaction resulting in the formation of a product composition comprising water, oxygen and unreacted hydrogen peroxide, the reaction expanding the product composition sufficiently to rupture the pressure release membrane and drive unreacted hydrogen peroxide through the opening in the container wall.
