Usage

General Description

2-Chloroheptafluoropropane, also known as HFC-227ea, is a chemical compound with the molecular formula C3HF7Cl. It is a colorless, non-flammable, and highly stable gas that is widely used as a fire extinguishing agent in total flooding fire suppression systems. Due to its low toxicity, it is considered to be a safe alternative to halon-based fire suppressants. 2-Chloroheptafluoropropane works by disrupting the chemical reaction of the fire and extinguishing it through heat absorption. It is also used in aerosol propellants, refrigerants, and foam-blowing agents, making it a versatile and valuable industrial chemical. However, it is important to handle this chemical with care and follow proper safety guidelines to prevent any potential health and environmental risks.

Novel Friedel-Crafts reaction method and catalyst thereof

The present invention relates to a novel method for preparing or synthesizing an acylated or alkylated aryl compound, such as acylated or alkylated benzene, through a reaction called Friedel-Crafts, and a novel catalyst for the method. The present invention particularly relates to a novel environment-friendly method for synthesizing the Friedel-Crafts reaction of the acylated or alkylated compound.

Compositions containing chromium, oxygen and gold, their preparation, and their use as catalysts and catalyst precursors

A catalyst composition is disclosed that includes chromium, oxygen, and gold as essential constituent elements. The amount of gold in the composition is from about 0.05 atom % to about 10 atom % based on the total amount of chromium and gold. Also disclosed is a process for changing the fluorine distribution (i.e., content and/or arrangement) in a hydrocarbon or halogenated hydrocarbon in the presence of the catalyst composition; and methods for preparing said catalyst composition. One preparation method involves; (a) co-precipitating a solid by adding ammonium hydroxide (aqueous ammonia) to an aqueous solution of a soluble gold salt and a soluble chromium salt that contains at least three moles of nitrate per mole of chromium in the solution and has a gold content of from about 0.05 atom % to about 10 atom % of the total content of gold and chromium in the solution to form an aqueous mixture containing co-precipitated solid; (b) drying the co-precipitated solid formed in (a); and (c) calcining the dried solid formed in (b) in an atmosphere containing at least 10% oxygen by volume. Another preparation method involves (a) impregnating solid chromium oxide with a solution of a soluble gold salt, (b) drying the impregnated chromium oxide prepared in (a); and optionally, (c) calcining the dried solid. A third preparation method involves (a) evaporating an aqueous solution of chromium(VI) oxide and a soluble gold salt to form a solid; (b) drying the solid formed in (a); and (c) calcining the dried solid formed in (b) in an atmosphere containing at least 10% oxygen by volume.

PROCESS FOR THE SYNTHESIS AND SEPARATION OF HYDROFLUOROOLEFINS

A process for the synthesis of fluorinated olefins of the formula CF3CF=CHX, wherein X is F or H comprising contacting hexafluoropropene with hydrogen chloride in the vapor phase, in the presence of a catalyst, at a temperature in the range from about 200 °C to about 350 °C, wherein the mole ratio of hydrogen chloride to hexafluoropropene is from about 2:1 to about 4:1, separating the 1-chloro-1,2,3,3,3-pentafluoro-1-propene, 1,1-dichloro-2,3,3,3-tetrafluoro-1-propene and hydrogen fluoride products from unreacted hexafluoropropene, and hydrogen chloride by distillation, hydrogenating either the 1-chloro-1,2,3,3,3-pentafluoro-1-propene, 1,1-dichloro-2,3,3,3-tetrafluoro-1-propene or mixture thereof over a catalyst, and dehydrochlorinating the said hydrogenation product to produce either 1225ye or 1234yf.
