I am and cleaning and cataloguing my lab for health and safety purposes at the moment it has year’s worth of accumulated lab chems. This is my last chance to make certain items disappear before anyone else knows about them

I would ask a question but my time is short
So here is a list of exciting chemicals, if any of them are USELESS could please inform me

And if you were in my shoes point me in the direction of some exciting things I could do not to excoriating though (maybe some sort of flash powder)

potassium persulfate purity? Orbeco don’t have the msds anymore cat number r-3926

nitrate powder rt-124
64% zinc 32% barium sulfate
http://www.orbeco.com/Pdf/RT-124.pdf

hach sulfide inhibitor
10-20% basic cupric carbonate
80-90% sodium nitrate
http://app.hach.com/pdf_storage/394243.pdf

zinc powder

zinc powder activated with copper

Mercuric thiocyanate 0.23% soln in 99" methanol

hach ferric ion soln <10% percholric acid

Karl Fischer solution B

Titianium tetra cholride

potassium iodate

silver nitrate

silver sulphate

sodium azide

potassium dichromate

Urea

Antimony 98.5%

cadmium coarse powder

Hexamine

30% hydrogen peroxide

mercuric sulfate

mercuric chloride

0.5M iodine volumetric soln

IGEMA Fluid (Ethylene dibromide and perchlorethylene)

Titanium tetrachloride for making instant smokescreens. :)

If you have all these chemicals accrued over years- Why do you need to ask what they can be used for?! Or are you about to clean out SOMEONE ELSE'S lab?

It's the end of the college school year, so go figure. ;)

no its the start of a new processing season I have been in the the lab for only three seasons

I mainly test waste and rendering products

the company has had new lab staff almost every year

they horde everything from old thermometers, hydrometers to broken stills and photomultiplyer tubes

I have heaps of old expired chems I can take a pic if you like rusty tins benzene with what looks like beer caps on top

I gave most harmless stuff away(to a high school) when I first started as I was shocked at the amount of surplus chems, and had to look like I was doing something about it.

my time is short.

Yeah, but his question and the list of chemicals makes it incredibly clear that he's not a chemistry student. If he was a chemistry student or was well read he'd know the safety precautions for azides, and thus the use of what he has.

I know azides are explosive.

They are the explosive used to inflate air bags (sodium azide more stable than lead and some of the other metal azides).

I use the azide in the lab in an azide iodide modifier for a water treatment test
its a shit of a thing to make up 500g of NaOH in 1L of d.H20 with about 100 or so grams of sodium iodide

I just thought there might be some sweet combo in there for some sort of interesting powder. I am not interested in anything too dangerous just some light hearted fun

I choose these things in particular as they seemed to be the most reactive and flammable for some sort of nice flash powder, a few others I wasn�t sure about so I included in the list.

I could have mentioned I have benzene, phenol, %65 nitric acid, conc H2SO4, toluene, xylene(I think, some idiot in the past put in one of those clear bottles with blue lids and labelled it xylene with a marker), glacial acetic acid (this stuff gives the most annoying burns skin feel very tight),formic acid, selenium, abs ethanol, 96% ethanol, methanol, propan-2-ol, petroleum spirit 40-60C BP, glycerol, octanol, HFl etc.

Etc but I don�t want to hurt myself or anyone or lose my job.

I can give you a number of chemicals tests that use some of these reagents if you would like, could make a nice cover for you guys

Eg ammonia nitrogen: phenate method uses phenol, Sodium nitroprusside, sodium hypocholrite, abs ethanol and some other stuff.

I don�t have much explosive chemistry knowledge yet, and those of you that are hobby chemists I commend your knowledge and interest in the subject

I am mainly an analytical food chemist in my job but studied chemistry, pharmacology and toxicology

my routine tests include moisture, fat, protein via TKN, ash for meat and bone meal, bone dust and dried blood(just moisture and protein), FFA, FAC and bleach on tallow, COD, BOD, TKN, NH3-N,total solids, total suspended and dissolved solids, oil and grease, floatable fat, total reactive phosphorous on waste water

This is not my personal lab but my work place:D

I'll go out on a limb here and wager he's no English major, either.

my time is short.
Agreed.

Agreed.


I do speak English but yes my spelling and grammar are poor a spell checker is far smarter than I

I didn’t what to ask any questions but I do have little time

I do have some books on the subject, but if you could give me the names of some really good ones that would be nice as well.

How dangerous is sodium azide if I hit a small crystal with a hammer would it make a noise?

Sorry for being a newbie but in time I could be of value.

I have some good hard texts on toxicology (cassret & Doull?), I also have the merck index but that’s up for download, Goodman’s and Gillman’s pharmacological basics of therapeutics, Advanced organic chemistry

I know about azides I have sodium azide its not that bad I make it up in a solution for water treatment (with NaOH and NaI), yes they are used as explosives, in car air bags, and for preservative in soln. However there doesn�t seem to be much mention of use of it in a "flashbang" powder or on its own, I actually have heaps of sodium azide

I don�t want to make any thing too dangerous as I have many other expired and routine chemicals I could have mentioned (Phenol, Benzene, H2SO4 conc, Fuming HCl, 65% Nitric acid, Xylene, Toluene, Silver Nitrate, HFl, NH3Cl etc.)

I chose the ones on the list in the first post as they are reactive or used in explosives, however there were a few I was wondering about as well hence the few that are not so hot

So if you have any interesting ideas that involve those listed or some other common compounds drop a reply :D

i also have many simple chemical tests i can tell you about that use many "useful" chemicals as cover if anyone wants. :cool:

There is no way to teach you what you want to know in one post. You have weeks, months or years of reading to do if you wish to learn this subject. It will not be good for your longevity to hurry into hands on experimentation. Your posts make it obvious you have essentially no knowledge base at this time.

Several books on the subject are available. They are discussed here at length, and are downloadable. SEARCH this site. I would suggest you start with Tenney Davis' Chemistry of Powder and Explosives.

Sodium azide is not a primary explosive. The main danger of it is toxicity, comparable to that of cyanide. You should have no difficulty finding out about THAT in the references you mention having.

I, and most others here will ignore you until you show evidence of having done some meaningful work towards educating yourself.

But I cant keep it all. :(

its just the time factor i can hide some in the lab but what would be best.

Cheers for the reference i have been reading what i can it helps being already chemistry educated.

sodium azide. yes but it is a solid so I am not going to be handling it without gloves glasses and a coat.

nothing is without its poision its strictly the dose that determines the poision

but yeah some are worse the others paraquat
