How to purchase white phosphorus
ALFREDO TIFI
is avalaible.
I want to buy a little bit for my school, for the chemistry lab.

There are a couple of reasons white P is commercially unavailable:
it's very hazardous (spontaneously combustible); and it's used in the
manufacture of illegal drugs. You won't be able to get it.

Is it commercially unavailable ?? Or just for the general public ?? As one of
the pranks I played back in HS was dissolving some in Carbon Disulfide ... Then
painting a word on a cement wall ... a little time later ... after the teacher
came into the lab ... the word burned into the wall ...
I am not an anarchist but my desire to become a chemist was that things burned
and exploded ... White P was just one of many fun things ...(and yes, i do have
all my fingers - I may have done stupid things ...but I did them all carefully
)
In the Village ....
I am not a number ... I am a free man !!!!

instance, fobchemicals.com, FMC CORP., Phosphorus Chemicals Div.,Rhodia
Specialty Phosphorus Products,Solutia Inc.and Pechiney World Trade
(USA), Inc.,Brandeis Chemical Division. But you may have to purchase a
truckload of it instead of a few grams. And talking about "impressive"
experiments with P4, the one with KClO3, CS2 and P4 comes to my mind. We
were shown this one in a InorgChem Lecture once, and surprisingly nobody
lost his hearing (but our ears were ringing all day long). It's an
experiment, _o_n_l_y_ experienced and careful chemists should do.

cells. In my day, the school chem. store certainly contained a jar of
white phosphorus sticks, carefully kept under water. The teacher was
left over from WW1 and at the end of the academic year would put on a
demo. One year the theme was "war gases" (he had samples!). Another year
it was "redox reactions". One of that year's dems was the "barking dogs
reaction": P4 in CS2 spotted onto filter circles resting on various
sizes of beaker ...
If all else fails, get the scholars to collect and save their urine.
Then you can distil/concentrate it (see many old general chemistry
texts).

Take a walk thru the Merck Index. Compare LD50 of potassium cyanide
to that of white phosphorus. Interesting.

That stuff is fun. It is used in military incendiaries and mainly to make
military smoke screens with titanium-oxide (white stuff in paint).
It's controlled because of these uses and because it burns when exposed to
air - safety concerns there.

Yes, but as a few people have noted above white P was much more fun to
play with when chemistry was fun and not smothered with safety regs.

This from:
Thorpe's Dictionary of Applied Chemistry 4th ed. 1949
[I would not use this for clinical judgment!!]
V. PHOSPHORUS AS AN INDUSTRIAL HAZARD.
The following dangers arise from the use of phosphorus in industry:
(ii)
The Poisonous Properties of the Solid.-Solid white phosphorus is
poisonous when taken internally, and is widely used in of rat and vermin
poisons, which normally contain 1-4% of phosphorus.
The toxic dose depends upon the personal peculiarities of the individual and
upon the physical state of the phosphorus, which governs the rate of
absorption. Recovery has occurred after the taking of about 400 mg. but in
general a dose of 50 mg. or above is liable to be fatal.
The symptoms are due to two causes, irritation of the gastro-intestinal tract
and the slower action of the absorbed poisons. The former causes abdominal
pain, nausea, vomiting, and diarrhoa, which develop during the first few
hours. Thirst is intense and the breath has a garlic-like odour. If the shock of
the first few hours is withstood then follow two or three days of comparative
well-being before the absorbed poisons come into full action. This action
causes further vomiting and diarrhoa, often nose-bleeding, headache,
weakness and enlargement of the liver. The patient usually dies about a
week after taking the poison.
Quick treatment is very desirable because of the speed with which
phosphorus is absorbed through the gastro-intestinal tract. A simple
treatment is to give the patient 0-25 g. of copper sulphate in a glass of water;
this coats the phosphorus with copper or copper phosphide. Gastric lavage
should also be performed as early as is possible, followed by Epsom salts.
Subsequent treatment includes a diet high in protein and carbohydrate but
low in fat, accompanied by injection of grape sugar and insulin. Large
doses of ascorbic acid, thiamine, and calcium gluconate are also said to be
valuable.
[Copper sulphate! I wonder is the cure is worse than the disease!]

PARKER, Colo. (UPI) _ Parker school officials are investigating an
incident in which seven students were sent to the hospital after eating
poisonous chemicals.
The students were taken to the AMI Healthcare Plaza-Centennial
facility Tuesday after complaining of nausea, stomach ache and a bad
taste in their mouths.
School officials said the students apparently consumed some copper
sulphate crystals, believing they were rock candy. All the students were
discharged from the hospital after treatment.

I always like the phosphine smoke ring(s) demo!!
This demo along with the entire "Smoke, Fire, and Explosions" chapter
was dropped from the 2nd ed. of Summerin & Early Jr's "Chemical
Demonstrations: A Source Book for Teachers. ACS. And ... Bassam
Shakhashiri's Chemical Demonstrations (Vol. 1) lists the 'Phosphine
Fire Flask" demo under "Dangerous Demonstrations" - We are aware of
the following systems and we judge them unsuitable as demonstrations.
In all cases the systems are extremely hazardous.
Say ... the P4/Br demo looks interesting ........!

They also took out the explosive decomposition of lead picrate :-~(

Yes it does :-) Small amts of red ph. inflame on contact with fl. Br

are much safer compositions that are also much cheaper & less
hazardous.....
