Picrates of some metals tend to be significantly more sensitive to impact, friction and shock than picric acid itself. (wikipedia.org)
Ethers and esters of picric acid are also called picrates. (wikipedia.org)
It is widely known that Picric Acid should not be allowed to contact metals or their salts due to the danger of formation of metal picrates. (power-labs.com)
Metal picrates are salts of Picric Acid formed by the addition of the metal to the 2,4,6TriNitroPhenol ring at the first hydroxide, as seen on the example to the left (KO-C 6 H 2 (NO 2 ) 3 or KC 6 H 2 N 3 O 7 ). (power-labs.com)
In this video, Tom Allgaier will show the actual procedure on how to synthesize Potassium picrate with hot water, picric acid, and potassium carbonate. (rumble.com)
These were mainly picric acid, picric sulfonic acid and unidentified picrate salts along with some hydrazines. (trinitynews.ie)
C9H12O2S) C,H,S. The picrate can be formed by treatment with a saturated EtOH solution of picric acid. (drugwiki.net)
Urinary creatinine concentrations are measured on an autoanalyzer using the Jaffe method, where creatinine combines with picric acid to form a creatinine-picrate complex that changes the absorbency of the solution. (jax.org)
Synthesize potassium picrate1
In order to synthesize potassium picrate using potassium carbonate the procedure remains the same except K2CO3 is substituted for KOH. (power-labs.com)
Methyl picrate1
The ether methyl picrate (CAS# 606-35-9) has the formula (O2N)3C6H2OCH3. (wikipedia.org)
Ammonium1
Many picrates are explosives, for example ammonium picrate (known as Dunnite). (wikipedia.org)
Salts1
The picrate ion is intensely yellow, although many of its salts are brown or orange-red. (wikipedia.org)
Lead picrate2
Some are used as primary explosives, namely lead picrate or potassium picrate which find their use as primers for cartridge ammunition. (wikipedia.org)
The two most interesting ones were Potassium and Lead Picrate (with Sodium Picrate being very weak). (power-labs.com)
Explosives2
Metal Picrates are sensitive explosives and as such should not be manufactured at all! (power-labs.com)
And some explosives (picrate based) start to form crystals as they age. (axishistory.com)
Crystals3
ABSTRACT: Single crystals of L-Valinium picrate were grown from aqueous solution by slow evaporation technique. (scirp.org)
The spectra of the crystals of pyridine picrate crude formula, C 11 H 8 N 4 O 7 , in the mid infrared (IR) and Raman are studied as a function of temperature. (academicjournals.org)
As the solution is cooled gradually to 0C, the potassium picrate crystallizes out of it in the form of a framework of long needle-shaped crystals. (power-labs.com)
Anion2
A picrate is a salt containing the anion (O2N)3C6H2O− or an ester derivative of the picrate anion. (wikipedia.org)
The synthesis of a simple fluorescent naphthalimide-based receptor N -allyl-4-iminodi( N -butylacetamide)-1,8-naphthalimide 3 was carried out as a selective picrate (Pic - ) anion probe, and the detecting behavior of this probe was studied by fluorescence spectroscopy. (degruyter.com)
Synthesis2
For curiosity's sake experiments were performed on the synthesis of a few metal picrates and they were tested as to their properties. (power-labs.com)
Below, the synthesis of a small potassium Picrate batch is outlined for informational purposes only. (power-labs.com)
Sensitive1
This phenomenon is essential for producing a highly selective and sensitive fluorescent probe for picrate anions. (degruyter.com)
Media1
TNP nitronates formed under these conditions are more unstable than the picrates in what they turn back after standing a while in neutral media (return to the yellow color). (power-labs.com)
High1
Most importantly, probe 3 has a high selectivity for picrate over competitive anions and picrate-containing analytes, which meet the selective requirements for practical application. (degruyter.com)
Picric acid3
Picrates of some metals tend to be significantly more sensitive to impact, friction and shock than picric acid itself. (wikipedia.org)
Ethers and esters of picric acid are also called picrates. (wikipedia.org)
I am not experienced in making energetics except for black gunpowder and nitrocellulose, both of which I've made a few times with great success (but no more than 10 grams of powder and 2 cotton balls at a time), and I wanted to try my hand at making small quantities of the following: RDX, ETN, Picric acid, Ammonium Picrate, Nickel Hydrazine Nitrate, and (possibly) DDNP. (sciencemadness.org)
Ferrous2
Ferrous picrate is used in some applications as a diesel fuel additive to achieve better mileage. (wikipedia.org)
One additive, ferrous picrate, lacked measurable effects on exhaust emissions. (cdc.gov)
Alkaline2
Serum and urinary creatinine concentrations were determined using the Jaffe kinetic alkaline picrate method. (medscape.com)
A standard method for determining urine creatinine levels is based on Jaffe's reaction, in which creatinine treated with an alkaline picrate solution yields a bright orange-red complex. (health-care-clinic.org)
