Discussion Overview

The discussion centers on the possibility of generating HOD clathrate by creating an interface between HOD and methane gas. Participants explore the theoretical implications and challenges associated with forming HOD clathrate, particularly in comparison to existing studies on methane hydrates involving H2O and D2O.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the feasibility of generating HOD clathrate, noting the lack of literature on the subject compared to methane hydrates with H2O and D2O.
  • Another participant mentions that pure HOD will equilibrate to a mixture of HOD, H2O, and D2O due to water's self-ionization.
  • A participant speculates that the bulk of HOD would equilibrate before it could freeze to methane clathrate and questions the partitioning of 'heavy methane'.
  • Further discussion suggests that attempts to create bulk HOD ice would result in a mixture before clathrate formation could occur, citing differential ionization rates and equilibria.
  • One participant asserts that pure HOD clathrate cannot be made due to self-ionization of liquid HOD, recommending reliance on existing D2O studies instead.
  • Concerns are raised about the stability of HOD in the liquid phase, which may explain the scarcity of literature on HOD clathrate.
  • A participant expresses a desire for alternative opinions but suggests that the discussion may be reaching a conclusion.

Areas of Agreement / Disagreement

Participants generally agree that pure HOD clathrate cannot be formed due to the self-ionization of HOD. However, there are differing views on the implications of this and the potential for further exploration of the topic.

Contextual Notes

The discussion highlights limitations related to the stability of HOD in the liquid phase and the potential for equilibria to affect clathrate formation. There are unresolved questions regarding the specifics of HOD's behavior in relation to methane clathrate synthesis.

Hi guys , Is it possible to generate HOD clathrate,I mean making interface of HOD and methane gas. i know there are studies on Methane hydrate(CH4+H20 and CH4+D20) but i could not see any literature about CH4+HOD . While HOD will be prepared from isotopic dillution of h2o and d2o.

I must say thanks in advance , If anybody have idea or any litrature source

Pure HOD will quickly equilibrate to a mixture of HOD, H2O, and D2O, due to water’s self-ionization.
 
At a guess, the bulk will equilibrate thus before it can freeze to methane clathrate.

Are you thinking about partition of 'heavy methane' etc ??

Not partition , i am looking for formation of HOD clathrate , just like h2o clathrate and d2o clathrate
 
Sorry, per @TW's reply, I'd suggest attempts to make bulk HOD ice would create a mix before a clathrate had time to form.

I wasn't very good at PhysChem, but I'd expect differential ionisation rates and equilibria between the HO and HD.

IIRC, this is why tracing biochemical pathways with 'heavy water' requires 'due care', and why bulk 'heavy water' may be considered 'mildly toxic'. My only experience was a little deuteration of some synthesis samples for NMR structure analysis, but we got the 'full-on' safety lecture.

( Plus an off-the-record tip on how much beer to bribe the NMR Tech team to 'hold' the goods elevator for the very best baseline in your scans... :wink:)

OT: Heavy Water may actually be cheaper than many snake-oils peddled but I've vague memories of its regular bulk ingestion being touted as an effective anti-ageing treatment before medical, nuclear and security authorities intervened...
 
@Sain bux - your question was answered by @TeethWhitener - basically you cannot make pure HOD clathrate.

Why?

Because liquid HOD self-ionizes (pure HOD -> H2O + HOD + D2O), and so any of the working clathrate synthesis models using HOD instead, will not produce pure HOD clathrate. Or put another way, use the D2O paper.

Can I ask why you want HOD clathrate? HOD is not 100% stable for long in the liquid phase, which, as a guess, is why the literature does not have much on it.
 
I think we are at an end point on this topic. If anyone has a well-founded opinion different from those expressed above please start another thread.
Thanks to everyone for helping. Thread closed.
