Abstract

A packaging unit for one or more of transport or storage of at least one organic peroxide. The packaging unit comprises one or more outer container, such as a transport container and/or a storage container. The packaging unit may also comprise an inner container. The outer container and/or the inner container is filled with the at least one organic peroxide. The packaging unit also comprises one or more extinguishing agent container filled with an extinguishing agent. The extinguishing agent container may be at least one bag and/or at least one bottle. The extinguishing agent container is separately introduced into one or more of a receiving area of the outer container or the inner container. The extinguishing agent container is removable from the outer container. The extinguishing agent container may be detachably connected to or not connected to the outer container, or the extinguishing agent container may be detachably connected to or not connected to the inner container. The extinguishing agent is released from the extinguishing agent container by heat-induced melting, bursting, burning or tearing of the extinguishing agent container.

Description

[0069] The invention shall be further illustrated by the following Figure and the following Examples.

[0070] FIG. 1 shows a view of a packaging unit (10) according to the invention, which contains an outer container (12) (preferably a carton) with four bottles filled with peroxide (which serve as inner containers (14)). According to the invention, bags (16) filled with water are located in the cavities of the outer container, which are evenly distributed around the bottles.

[0071] FIG. 1A shows a side view, FIG. 1B a top view of the packaging unit (10).

EXAMPLES

[0072] For both liquid organic peroxides (Example 1) and solid organic peroxides (Example 2), the addition of water-filled bags to the packaging unit reduced the burn rate of the organic peroxide.

Example 1—Methyl Ethyl Ketone Peroxide Norox Mekp-9

[0073] A standard package of NOROX MEKP-9 consisting of 4×8 U.S. pound (lbs) bottles (inner containers) contained in a carton (outer container) had 6×500 g water bags placed in each cavity between the bottles in the carton. This included one bag in each of the outer corners and two bags in the center between the bottles.

[0074] Set-up of the burn tests: Six cartons were placed on a wooden pallet surrounded by wooden slats. Between the wooden slats is wood wool, which was soaked with a gasoline/diesel mixture and ignited by means of an electric igniter. The thermal radiation of the burning is registered by means of four sensors and the burn rate is determined in accordance with Sprengstofflagerrichtlinie 011 (SprengLR 011) (“Explosives Storage Guideline 011”) and BG Regulation B4 (DGUV Regulation 13). For comparison, the test was repeated without the water packs.

[0075] It could be shown that the addition of water-filled bags to the standard packaging reduces the burn rate by about half (Table 2, entries 1 and 2).

[0076] In the case of the smaller single packagings with one 8 lbs bottle, the burn rate was significantly higher than in the case of packagings with 4×8 lbs bottles. Also in this case the burn rate could be reduced by adding water bags. (Table 2, entries 3 and 4). It could thus be shown that storage and transport safety can be increased.

Example 2—Bis(4-Tert-Butylcyclohexyl) Peroxydicarbonate (Bchpc)

[0077] The standard packaging of BCHPC consists of a carton (outer container) with 4×5 kg sacks (inner containers) of BCHPC. Each sack in turn contains a bag filled with 1.25 kg of water.

[0078] Set-up of the burn test: Six cartons were placed on a wooden pallet surrounded by wooden slats. Wood wool was placed between the wooden slats, impregnated with a gasoline/diesel mixture and ignited by means of an electric igniter. The thermal radiation of the burn was registered by means of four sensors and the burn rate was determined in accordance with Sprengstofflagerrichtlinie 011 (SprengLR 011) (“Explosives Storage Guideline 011”) and BG Regulation B4 (DGUV Regulation 13) (Ref. 2 BAM report dated Sep. 4, 2019, Ref. 3 UN Manual of Tests and Criteria; Paragraph 51).

[0079] When water-filled bags were added, the burn rate also decreased in the case of solids. The example concerning bis-(tert-butylcyclohexyl)-peroxydicarbonate (BCHPC) shows that the burn rate can be reduced by approx. 300 kg/min by adding water bags (see Table 3).

Example 3—Burn Tests with Different Organic Peroxides

[0080] Burn tests were carried out with 100 g peroxide in each case. The respective peroxide was first burned without adding water bags and the burn speed was determined in kg/(min*m.sup.2) according to standardized procedures.

[0081] The same tests were then repeated, with two or four bags, each containing 5 g of water, being added to the respective 100 g peroxide in the container. In these tests, too, the burn speed was determined in kg/(min*m.sup.2).

[0082] Table 4 shows the results of the burn tests, indicating the relative burn speed of the respective peroxides.
