Propionic Acid

Propanoic acid is a naturally-occurring carboxylic acid. The salts and esters of propanoic acid are known as propanoates. It is consumed as a preservative for both animal feed and food for human consumption. It is also useful as an intermediate in the production of other chemicals, especially polymers. It is also used to make pesticides and pharmaceuticals. The esters of propanoic acid have fruit-like odors and are sometimes used as solvents or artificial flavorings.

Propylene Glycol

Propylene Glycol is an organic compound. Large amount of it is used in the plastics industry for the manufacture of polyester fibers and alkyd resins. It is used as a main ingredient in automobile antifreeze and engine-cooling liquids and in brake and hydraulic fluids due to its useful properties of low freezing point, involatility and low corrosive activity. It is used in the preparation of body-care surfactants and also as a humectant in foods and cosmetics. It is used as a solvent for colouring or flavouring agents as well as in many oral, injectable or topical pharmaceuticals. Its antibacterial property is applied in the preparation of sanitizing lotions.

Pyridine

Pyridine is a basic heterocyclic organic compound. It was discovered in 1849 by the Scottish chemist Thomas Anderson as one of the constituents of bone oil. Two years later, Anderson isolated pure pyridine through fractional distillation of the oil. It is used as a precursor to agrochemicals and pharmaceuticals and is also an important solvent and reagent. Pyridine is added to ethanol to make it unsuitable for drinking. It is used in the synthesis of sulfapyridine, antihistaminic drugs tripelennamine and mepyramine, as well as water repellents, bactericides and herbicides.

Pyridinium Chlorochromate

Pyridinium chlorochromate is a reddish orange solid reagent used to oxidize primary alcohols to aldehydes and secondary alcohols to ketones. It will not fully oxidize a primary alcohol to the carboxylic acid as does the Jones reagent. A disadvantage to pyridinium chlorochromate using is its toxicity. It was developed by Elias James Corey and William Suggs in 1975. Pyridinium dichromate is a similar oxidizing agent, which has the advantage of being less acidic.

Rhenium Rod Industrial Grade 99.9%

Rhenium metal is silvery rod, bar, stick, plate, sheet, foil, strip, coil and powder. It exists in soot from calcinator for molybdenite and copper ore, which is byproduct of refining molybdenum and copper. Ammonium perrhenate (NH4ReO4) and potassium perrhenate(KReO4) are the raw materials.  Its chemical properties are close to manganese and technetium.

Rhenium Metal 

CAS No.:7440-15-5 EINECS No.: 231-124-5 Molecular Formula:Re Molecular Weight:186.207
Melting Point:3180℃ Boiling Point:5900℃ Density:21.04 UN 3178 4.1/PG 2

Applications

Rhenium metal bar is mainly for nickel-rhenium alloys, which apply to manufacturing combustor, turbine blade and exhaust nozzle of jet engine.  These alloys contains 6% rhenium at highest.

Rhenium can enhance physical property of tungsten. W-Re alloys have better plasticity at low temperature and high-temperature stability is better too, which is easy to process and shape. The change increase with the amount of rhenium increase, so W-Re alloy contains 27% rhenium, which is also the solublity limit of rhenium in tungsten. The alloys can apply to X-ray sources and thermocouple

In chemical industry, rhenium metal powder can use as catalyst for dehydrogenation.  Rhenium metal powder is raw material for Pt-Re catalys that is for producing gasoline without lead and high octane.  It is for spectral analysis too.

Rhodium Chloride Hydrate Industrial Grade 99.9%

Rhodium chloride hydrate is dark red crystalline powder, which is a precious metal compound. It has odor of acid and tend to deliquesce. When temperature is above 100℃, it starts to decompose into Rh2O3 and HCl. Rhodium(III) chloride is soluble in water, hydrochloric acid, acetone and ethyl alcohol, however not soluble in diethyl ether. Sponge rhodium metal is the raw material.
