Convert Cellulose to Alkane: Process Explained

AI Thread Summary
The discussion centers on the feasibility of converting cellulose into alkanes. It highlights that while cellulose is a complex sugar chain, its structure makes direct conversion to alkanes impractical and cost-inefficient. Instead, cellulosic ethanol is identified as a more viable alternative for fuel production. One participant shares their successful experiments in converting cellulose to glucose, suggesting that alkanes could theoretically be produced by oxidizing glucose and then using the Wolff-Kishner Reduction to replace carbonyl groups with hydrogen. The method for hydrating cellulose involved mechanical milling with a catalyst, although specific details are withheld due to ongoing publication efforts.

I'm just curious, what would the process be if someone wanted to change cellulose into an alkane? (I don't plan to try it. If I wanted an alkane then I could just go to the gas station.)

Can't quite be done really. (in any manner cost efficient enough to be sensible) Cellulose is just a (very branched) sugar chain, so you don't have any individual carbon chains longer than the 6 in glucose, and each of those has a hydroxo group on it, meaning you'd have to reduce that to get an alkane.

For fuel purposes, cellulosic ethanol is where it's at.
 
I saw an article on this last week. I believe it was PhysOrg. Anyway, http://www.sciencemag.org/cgi/content/abstract/308/5727/1446?hits=10&RESULTFORMAT=&FIRSTINDEX=0&maxtoshow=&journalcode=sci&HITS=10&fulltext=Production+of+Liquid+Alkanes+by+Aqueous-phase+Processing+of&searchid=1140726225359_13321"

I have conducted experiments in which I have successfully converted cellulose into glucose. If you wanted an alkane, in theory, you could oxidize all the -OH of glucose to their respective aldehydes or ketones and treat them with hydrazine/KOH (Wolff-Kishner Reduction) to replace all C=O with H-C-H
 
How did you hydrate the cellulose?
 
Mechanical milling with the aid of a catalyst. I can't really divulge into details because we're submitting the article for publication.
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
