a-Naphthylamine

a-Naphthylamine is an aromatic amine derived from naphthalene.It crystallizes in colorless needles which melt at 50 °C.It possesses a disagreeable odor, sublimes readily, and turns brown on exposure to air.a-Naphthylamine is the precursor to a variety of dyes.It can be prepared by reducing 1-nitronaphthalene with iron and hydrochloric acid at about 70 °C. After the reaction mixture is neutralized with milk of lime, the naphthylamine steam-distilled.a-Naphthylamine can also be prepared, in the form of its acetyl derivative, by heating 1-naphthol with sodium acetate, ammonium chloride and acetic acid; by heating 1-naphthol with calcium chloride-ammonia to 270 °C; and by heating pyromucic acid, aniline, zinc chloride and lime to 300 °C.

acetic acid

Acetic acid is an organic acid that gives vinegar its sour taste and pungent smell. It is a weak acid, in that it is only a partially dissociated acid in an aqueous solution. It is an important chemical reagent and industrial chemical, used in the production of polyethylene terephthalate mainly used in soft drink bottles; cellulose acetate, mainly for photographic film; and polyvinyl acetate for wood glue, as well as synthetic fibres and fabrics. In households, diluted acetic acid is often used in descaling agents. It is also used as a food additive.

ammonium fluoride lab grade 99.99% LAB GRADE 99.999%

Ammonium fluoride is colorless needle-like or lobate crystal, which is ionic compounds. It tend to deliquesce in air. When heating, it breaks up to ammonia and hydrogen fluroide. NH4F  dissolve in water and alcohol, but not in acetone and liquid ammonia.  It corrode glass. Hydrofluoric acid anhydrous and liquid ammonia are the raw material.

Ammonium Fluoride:

CAS No.: 12125-01-8EINECS No.: 235-185-9Molecular Formula: NH4FMolecular Weight:37.04Density: 1.05UN 2505 6.1/PG 3Melting Point:98? 

Applications:

NH4F solution can be as detergent and corrosive, which can confect with hydrofluoric acid to get buffer solution. Its MOS grades are mainly for integrated circuit of  medium, large scale. The BVIII grades are mainly for IC production.  It play a role in producing beryllium metal from beryllium oxide.

Its uses include extraction of rare elements, etching agent of ground glass, chemical polish of metal surface treatment, sanitizer and aseptic of making wine and mordant of fiber.

Ammonium fluoride get uses in ceramic and magnesium alloy. It can etch titanium wafer and silicon wafer.  It is a kind of analytical reagent and covering agent too.

Ammonium Metavanadate

 

Ammonium metavanadate is a kind of inorganic chemical that is white crystalline powder. Its main applications cover chemical reagent, catalyst, drier and pigment.  It dissolves in hot water and dilute ammonia water.

Ammonium Metavanadate

It tend to absorb moisture in air. When heating,  ammonia and water would lose. Ammonium metavanadate dissolves in hot water and dilute ammonia water and faintly dissolve in cold water, however not in ethyl alcohol. It has some other product names like ammonium vanadate and  ammonium vanadium oxide, which refer to same chemical.

Density:2.32g/cm3 Melting Point:210℃ UN Code: UN2859 6.1/PG 2  

Applications

Ammonium metavanadate is a kind of minor metal salts. it serve the purpose of chemical reagents, catalyzer, dryer and mordant usually, further which is also widely used as glaze in ceramics. It is is raw material in producing vanadium pentoxide. Their property is very close. In instrumental analysis, it acts as reagent to analyze phenols by thin layer chromatography and penicillin and thiodiphenylamine by spectrophotometry method.
