7783-89-3 Usage
Description
Silver bromate, also known as silver(I) bromate, is an inorganic compound with the chemical formula AgBrO3. It is a white powder or lumps and is known for its strong oxidizing properties. Due to its reactivity, it is used in various chemical reactions and processes.
Uses
Used in Chemical Synthesis:
Silver bromate is used as an oxidizing agent for the transformation of tetrahydropyranyl ethers to carbonyl compounds. This application is particularly useful in organic synthesis, where selective oxidation is required to obtain specific products.
Used in Analytical Chemistry:
Due to its strong oxidizing nature, silver bromate can be employed in analytical chemistry for the detection and quantification of various substances. Its reactivity allows for the development of sensitive and selective analytical methods.
Used in Photography:
In the past, silver bromate was used in the photography industry as a component of photographic emulsions. Its light-sensitive properties made it suitable for use in film and paper production, although it has been largely replaced by other compounds in modern times.
Purification Methods
It crystallises from hot water (80mL/g). It reacts with bromine water to form bromic acid (HBrO3) which is a strong oxidising agent. Store it in the dark.
Check Digit Verification of cas no
The CAS Registry Mumber 7783-89-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7783-89:
(6*7)+(5*7)+(4*8)+(3*3)+(2*8)+(1*9)=143
143 % 10 = 3
So 7783-89-3 is a valid CAS Registry Number.

Hydrates of Organic Compounds. VII. The Effect of Anions on the Formation of Clathrate Hydrates of Tetrabutylammonium Salts

Phase diagrams of the binary mixtures of tetrabutylammonium salt nX (X = NO2, NO3, BrO3, ClO3, IO3, ClO4, MnO4, and NCS for n = 1; X = CO3, SO4, WO4, and CrO4 for n = 2; and X = PO4 for n = 3) with water were determined over the temperature range between -10 and +50 deg C.From these diagrams the following results were obtained: (1) the formation of a clathrate-like hydrate for salts having such anions as NO2-, NO3-, BrO3-, ClO3-, IO3-, SO42- and PO43- was newly confirmed; (2) the melting point of the clathrate hydrate of the salt with monovalent anion was appreciably influenced by the kind of anion; (3) in the hydrates of the salt having either di- or trivalent anions, the melting points were relatively high and were only slightly affected by the kind of anion; (4) the crystal structure of these hydrates was essentially the same as that of the tetrabutylammonium fluoride hydrate, judging from the hydration numbers; (5) the solubilities in water of both permanganate and perchlorate were markedly lower than that of the iodide; and (6) in the thiocyanate system a phase separation into two liquid phases was observed at temperatures higher than +3.5 deg C.The effect of a monovalent anion on the stability of the clathrate hydrate was discussed in connection with the conventional partial molal volume of the anion.
