2 ethylhexanoate used in comparative example a the container was heated to cause peroxide decomposition some peroxide was released through the conduit however the container internal pressure reached 7 8 bar at which point part of the container wall broke a test identical to comparative example b was carried out except the 12 mm dia opening was replaced by a 12 mm dia rupture disk in the bottom of the container at an internal pressure of 0 5 bars the rupture disk burst releasing the container liquids and avoiding explosion the internal pressure reached only 0 5 bar a test identical to comparative example e was performed except 90 raschig rings 34 mm i d 40 mm o d 40 mm l were placed in the container the peroxide was heated and peroxide decomposition occurred the container contents were released the container internal pressure reached less than 0 05 bar no explosion occurred a test identical to example 2 was performed except 45 hollow spheres type solef pvdf avoidable from euromatic of 38 mm diameter were floating on top of the peroxide the container was filled with bis 3 5 5 trimethylhexanoyl peroxide 6 7 liters of a 75 solution diluted with isododecane and heated until peroxide decomposition occurred the container contents were released the container internal pressure reached less than 0 1 bar no explosion occurred a 65 liter container 0 4 m dia u00d7 0 6 m constructed of stainless steel was built with a 22 mm dia dip pipe substantially in accordance with the design of fig1 the dip pipe inlet was located 11 mm from the bottom of the container the dip pipe outlet was secured at the top of the container the container.
