Title: ~Tangible Products~
Post by: BetaAmyloid on November 18, 2009, 09:24:24 PM
So, this kind of relates back to my "project" thread...but, I would like to specify a project I would like to do.

The question is:

Do you guys know of any experiments (that you have done or not done) that allows a person to mix chemical 'a' with chemical 'b' (with chemical 'c'...etc etc if necessary) that creates a product substance 'p.'

This question is somewhat vague, but I would like to have a lot of ideas. Even something (totally elementary) as simple as mixing a couple of chemicals to form some type of substance that hardens to form a "bouncy" ball.

Also, I most likely have all necessary equipment to do a large variety of experiments.

Any experiments like this - things I can handle...keep...store. Any cool experiments to observe extreme changes of states of matter, etc.

Thanks. :)

You can make silly putty or something fairly similiar with silicone oil, something, and boric acid IIRC...

elephant toothpase is a good one to demonstrate extreme changes in states of matter.. perhaps?

Alright, I can google elephant toothpaste...but what are the procedures (chemicals) for silly putty? - Besides mixing common kitchen ingredients...like eggs, flour, etc.

Thanks :)

adding conc sulpuric acid to sugar, lots of steam liberation and formation of a carbon tower.

JGK, that is cool! What is this reaction making?

Thanks :)

"liberation of steam" "formation of a carbon tower"

water and carbon :P

Ah...thank you nj_bartel.  :'(  :'(  :'(

So,

H2SO4 + C12H22O11 :rarrow: 12C + 11H2O + H2SO4  ??

That's what I kinda meant to ask.  ;D

It partially oxidizes it also.. so it produces CO, and SO2 to some degree.

Its not really a full reaction, and it has side reactions so you can't really right it out.. but the main reaction is just the dehydration of sugar via sulfuric acid producing dilute sulfuric acid, and carbon.

elephant toothpaste uses conc. H2O2 and a catalyst such as KMnO2, MnO2, etc AFAIK.

Ohh, okay, that makes sense.

Thanks indie and nj!  :D

A bouncy ball?

ppt out the casein from milk with acetic acid.  You can then filter and ball it up; I accidentally dropped the filter ball and was surprised at the bounciness. It was an unintended consequence.  I was extracting lactose from milk.

Also
HCl(g) +NH3(g) ---> NH4Cl (s)

Your question is incredibly vague.  Most chemistry is mix a and b and get c.
Unless you mean with no byproducts, then it gets tricky.

Another fun one 10mL acetone +500mL 5.25% NaOCl (bleach) when chilled and allowed to sit for a while will precipitate out a 5-10mL blob of chloroform.

Thanks 408, I'll try it all!  ;D

What was it you wanted the lactose for? Did you ever successfully get any pure lactose?
Title: Re: ~Tangible Products~
Post by: 408 on November 20, 2009, 10:06:57 PM
Yes I isolated the lactose successfully.  This was a procedure out of a 60s lab manual.  But shitty reagents and being young with little experience meant my yield was lower than literature though.

As for why....Why not?

Ever try to make oleum or thionyl chloride, 408?

Post by: BetaAmyloid on November 20, 2009, 11:10:01 PM
Hey 408,

Does this chloroform introduce any type of serious injury? I'm reading that it can cause incapacitation, is this from smelling the fumes of gas or from drinking the substance?

Thanks :)

You should avoid breathing the fumes.  In addition to being carcinogenic, chloroform has historic use in medicine as an anasethetic and crime as the liquid used on 'knockout rags'

Yeah! That's where I've heard it from...

Thanks :)

If you then react it(chloroform) with acetone and sodium hydroxide, you can extract out 'chlorobutanol', a topical anesthetic :P

In quotes because that is a non-iupac name that could cause confusion in regard to its structure.

In what order should the reactants be mixed?...or does it matter?
Title: Re: ~Tangible Products~
Post by: csrscience.com on November 21, 2009, 08:27:09 PM
It matters - Um... I don't think you want to make it. It is a drug similiar to chloral hydrate - which is a scheduled substance!
 I mean.. it would be fun to make, but it just isn't the best thing to walk around telling people you've made it.

Time to introduce you to an amazing website

http://www.sciencemadness.org/talk/viewthread.php?tid=1415

Browse there.  Many many home experiments ranging from beginner to really advanced.

Cool, thanks for the link 408.

Sciencemadness really is the best chemistry experiment site on the English speaking web AFAIK...
Be careful what you post though, they can be a bit picky IMO.

Post by: 408 on November 21, 2009, 09:07:45 PM
Agreed.  There are a few non-english ones rumored to be good, but not speaking any of their languages I cannot comment.

As long as you do not ask stuff easily found by searching or anything regarding drug cookery or uninformed/unsafe explosives questions you are good to go.

Just not that NaOH is strong enough a base to form the carbene, which can go on to form phosgene, not really the sort of thing you want to be handling "in the garage"...
Title: Re: ~Tangible Products~
Post by: 408 on November 23, 2009, 02:43:34 PM
While I cannot say that no phosgene could be formed, I can say I did this when 15, in an unventilated basement in a stoppered flask with no ill effects.

With such an excess of acetone I would be surprised if any carbene could escape.
