==Peroxide as fuel==

There are some links to this article from submarine articles that talk about the use of peroxide as fuel. Could someone who is familiar with this add some text on that subject? Thank you. -- [[User:Jeffq|Jeff Q]] 10:53, 27 May 2004 (UTC)
: I will move those links to [[hydrogen peroxide]], since that is the peroxide they are talking about. I will copy your comments to [[Talk:Hydrogen peroxide]]. [[User:Securiger|Securiger]] 01:38, 5 Oct 2004 (UTC) 

I have also heard that [[John D. Carmack|John Carmack]]'s [[Armadillo Aerospace]] wanted to use 90 % peroxide as fuel for their rocket (but couldn't get it). Anyone qualified to comment on peroxide's use as submarine or rocket fuel? :) [[User:Brutulf|Brutulf]] 18:37, Oct 4, 2004 (UTC)
:See above re copying comments. BTW I find it difficult to believe that an aerospace researcher could not obtain 90% H2O2; it is reasonably common as an industrial chemical. [[User:Securiger|Securiger]] 01:38, 5 Oct 2004 (UTC)

:: Going back to WWII german and japanes rocket planes uses 
hydrogen peroxide as fuel. Solid peroxide have disadvantages over Ammoniuperchlorate which is normaly used. [[User:Stone|Stone]] 19:58, 1 February 2006 (UTC)


:: Hydrogenperoxide is traded u to 30 % (in water). Getting higher concentrations would be very difficult. Certainly not from the usual vendors like Aldrich, Fluka etc.  Higher concentrations can be achieved through extraction (H2O2 is more soluble in many organic solvents than H2O). The Me 163 Rocketplane used 90 % H2O2 ("T-Stoff"), the 2nd component ("C-Stoff") was a methanol-hydrazine mixture. 
90 % H2O2 is a very hazardous material. It can set pretty much anything on fire (there are you tube videos based on Me 163  WWII footage, like http://ca.youtube.com/watch?v=eIaUk4Mk2ko). It can also detonate if a suitable catalyst (can be dust or some other kind of dirt) is introduced.

The use of H2O2 for WWII submarine propulsion was suggested as (a) single fuel decomposed in a controlled way in a steam turbine (b) substitute for air in combination with classic diesel engines. (-> Walter engine)
The Kursk explosion was claimed to be the result of an accident with a high speed torpedo using 90 % H2O2. Friday Nov 28. 2008 Michael K.

== From PNA/Chemicals: cleanup request ==

*[[Peroxide]] needs to be cleaned up to a higher standard. It can refer to [[hydrogen peroxide]] in common use or other kinds of peroxides in chemistry. Perhaps it needs to be changed into a disambiguation listing different kinds of peroxides. --[[User:King of Hearts|King of Hearts]] 01:38, 13 December 2005 (UTC)

This is just a mess. A disambiguation page might be a good idea...Or perhaps a sentence at the top (peroxide can also refer to hydrogen [[peroxide]], a common rocket fuel, etc.

Also, the organization is bad. why dont't we just split it up into chemical properties, occurance/manufacturing and use?[[User:Ed-it|Ed-it]] 02:33, 19 September 2006 (UTC)

== Peroxide as a cure for disease ==

I was recently told that ingesting peroxide would cure diseases and keep you healthy. Also that one individual's Diabetes was cured by this method. It will also keep your pets healthy if added to their drinking water. Does anyone have any knowledge of this? Any vet out there know how it might affect a puppy? Thanks.  <small><span class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Sonnyt|Sonnyt]] ([[User talk:Sonnyt|talk]] • [[Special:Contributions/Sonnyt|contribs]]) 15:34, 19 October 2009 (UTC)</span></small><!-- Template:Unsigned --> <!--Autosigned by SineBot-->

==CE==
"...is one of the cell poisons"--I am not sure how to take this. Burn this after reading. [[User:Drmies|Drmies]] ([[User talk:Drmies|talk]]) 02:22, 23 December 2010 (UTC)
:Hm.. it adversely affects (through oxidation) body functions at the level of individual cells. Not sure about the most suitable term here. Maybe [[toxin]]? [[User:Materialscientist|Materialscientist]] ([[User talk:Materialscientist|talk]]) 03:18, 23 December 2010 (UTC)
::I made a minor edit. See what you think. My apologies for that silly typo, BTW. [[User:Drmies|Drmies]] ([[User talk:Drmies|talk]]) 04:17, 23 December 2010 (UTC)

==Applications: dibenzoyl? benzil? benzoyl peroxide?==
There's probably an error in the 1st part of the "Applications" heading, mentioning "dibenzoyl".  The structure of "dibenzoyl" disagrees with the structure shown on the linked page (dibenzoyl redirects to benzil); instead, I think it's benzoyl peroxide, which is a different compound.  I don't know enough chemistry to fix this, but someone ought to.  [[User:Oaklandguy|Oaklandguy]] ([[User talk:Oaklandguy|talk]]) 04:18, 27 December 2010 (UTC)
:Fixed. Thanks! [[User:Materialscientist|Materialscientist]] ([[User talk:Materialscientist|talk]]) 04:24, 27 December 2010 (UTC)

===Defect formation in fluorite dioxides===
"Both CeO<sub>2</sub> and ThO<sub>2</sub> accommodate excess oxygen in their lattice by formaing peroxide molecules.<ref>
{{cite journal|author=Middleburgh S. C., Lumpkin G.R. and Grimes R.W.|title= Accommodation of Excess Oxygen in Fluorite Dioxides |url=https://dx.doi.org/10.1016/j.ssi.2013.09.020|year=2013|journal=Solid State Ionics|volume=253|pages=119–122|doi=10.1016/j.ssi.2013.09.020}}</ref> This is in contrast to UO<sub>2</sub>, which takes in excess oxygen by forming charged interstitials. The accommodation of excess oxygen in these systems changes their thermal and diffusion properties. This will have implications in the oxides' use in nuclear fuels and solid oxide fuel cells. Adding oxygen to the CeO<sub>2</sub> system, for example, will increase the diffusivity of the oxygen allowing for more efficient solid oxide fuel cells."
The above paragraph was removed by me because it seems rather specialized and not noteworthy.--[[User:Smokefoot|Smokefoot]] ([[User talk:Smokefoot|talk]]) 16:46, 11 November 2017 (UTC)

== Hydrogen Peroxide not a peroxide ==

According to the cited IUPAC definition of peroxide (https://doi.org/10.1351%2Fgoldbook.P04510 ), hydrogen peroxide is not a peroxide, since a hydrogen atom is not an organyl group.  Really quite amazing.[[User:CountMacula|CountMacula]] ([[User talk:CountMacula|talk]]) 12:52, 5 April 2021 (UTC)

Proposal for improvements to the peroxide stub article:

Content:
I propose including “peroxide linkage”, which is a description of the bond shared by both oxygen atoms. It could help with the classification of a peroxide molecule, highlighting the properties of the peroxide functional group and hopefully differentiating it further from the specific “hydrogen peroxide”. Emphasis would be placed on the fact that peroxides are a class of molecule with this specific linkage/functional group, including but not limited to hydrogen peroxide. Properties of the bond, such as sterics and oxidation states of the involved atoms, could be added to this section as well. 

Images:
The images on the page are limited to 2D molecular structures. I believe that adding a 3D molecular structure would be beneficial in order to comprehensively show bond angles present in peroxides.
Another potential improvement could be the expansion of the caption on the “types of peroxides” image. At current, this caption only identifies the molecules, but does not explain how they fit into the peroxide category.

Sources:
The claim regarding peroxide nomenclature and Thomas Thomson will be verified by a source other than an online etymology dictionary. Ideally a primary source or record of this fact will be found. If a credible source cannot be located, this statement will be removed.  <!-- Template:Unsigned --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Norquay917|Norquay917]] ([[User talk:Norquay917#top|talk]] • [[Special:Contributions/Norquay917|contribs]]) 21:34, 13 March 2024 (UTC)</small> <!--Autosigned by SineBot-->
:{{ping| Norquay917}}.  This article is an ''overview'' and disambiguation, directing readers to the individual types of peroxides, each of which has its own distinctive properties.  --[[User:Smokefoot|Smokefoot]] ([[User talk:Smokefoot|talk]]) 21:51, 13 March 2024 (UTC)
