dehydration of sucrose.
apparently:
C6H12O6 + H2SO4 => C + H2o + H2SO4 (some balancing needed)
as the h2so4 is remaining a spectator why then will HCl not perform the same under teh same conditions?

Re: dehydration of sucrose.
have you noticed that no one is answering your question
fuckwittedness its called
on your part
now knock it off with the numbers and letters..
and tell us what is with what
and what isnt happening

Re: dehydration of sucrose.
i would assume that anybody on a chemistry forum would understand what C6H12O6 (glucose) is.
anyway. the problem is this; based on that reaction H2SO4 is just a catalyst for sugar to be broken down into carbon and steam.
why then doesn't HCl work in the same way?
or does the sulphate ion in particular do somehting ?

Re: dehydration of sucrose.
look smart arse,,
this is a learning forum,,
use there names,,not there numbers,,
so all levels can learn from you,,
now from a street level mentality,
who doesnt know dick,
if you cut with glucose,icing sugar, glucodin, etc etc
and it moistens up,,
you can not get it dry with out dessicating it,,
and caramelization is an easy mistake to make
why wont the mix of meth and a sugar based cut not solidify??
fucked if i know..
what i do know is not to do it...

Re: dehydration of sucrose.
Sulfuric Acid, is a much, much stronger dehydration agent than Hydrochloric acid. That would be my guess to why thats the case. If you could try it with Phosphoric Acid, the reaction should occur even faster.
Hydrochloric Acid also, if memory serves me right, will cleave the Glucose molecule into half, but without my chemistry text's i can't remember if this is what's happening or if I'm getting the Cyclic chemistry confused with the organic again.

Re: dehydration of sucrose.
whats with the negativity?
if its a learning forum why cant i learn from you guys?
the formulas should be staple knowledge for anybody in a chemistry forum.
where the fuck did drugs come from?
i want the carbon that comes from the sucrose for a BP mix.

Re: dehydration of sucrose.
If you direct your question specifically to Tryptamine, then you're more likely to get an answer. He is the board's resident chemistry expert.

Re: dehydration of sucrose.
kirby. why dont instead of of trying to compensate for you lack of chemistry knowledge by bellitling others you attempt to answer the question.
if tryp could help out with this one it would be much appreciated.

Re: dehydration of sucrose.
Well sulphuric acid has a great affinity for water, hydrochloric is at the very least 62% water so it doesn't really want to suck the water out of everything like pure sulphuric. Mind you even pure gaseous HCl doesn't have that strong affinity far water, it is just the nature of the animal, or species.
HCl will not cleave glucose, but it will hydrolyse sucrose into fructse and glucose a mixture known as invert sugar.

Re: dehydration of sucrose.
I have some C left over from this reaction in my shed. The problem is, I have no KNO3 right now, so I can't test it, but from what I heard around, It won't work too well for BP.

Re: dehydration of sucrose.
in theory the C from this reaction should work better than charcoal. it is pure except for the "bubbles" in it which is trapped steam as a result of the strongly exothermic reaction.
perhaps you would need to crush the C then dry in a moderate oven for a while.
