Acetyl chloride was first prepared in 1852 by French chemist Charles Gerhardt by treating potassium acetate with phosphoryl chloride. [4]Acetyl chloride is produced in the laboratory by the reaction of acetic acid with chlorodehydrating agents such as phosphorus trichloride (PCl 3), phosphorus pentachloride (PCl 5), sulfuryl chloride (SO 2 Cl 2), phosgene, or thionyl chloride (SOCl 2).
Flammability diagrams show the control of flammability in mixtures of fuel, oxygen and an inert gas, typically nitrogen. Mixtures of the three gasses are usually depicted in a triangular diagram, known as a ternary plot. Such diagrams are available in the speciality literature. [ 1][ 2][ 3] The same information can be depicted in a normal ...
Combustibility and flammability. A combustible material is a material that can burn (i.e., sustain a flame) in air under certain conditions. A material is flammable if it ignites easily at ambient temperatures. In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame.
Thionyl chloride is an inorganic compound with the chemical formula SOCl 2.It is a moderately volatile, colourless liquid with an unpleasant acrid odour.Thionyl chloride is primarily used as a chlorinating reagent, with approximately 45,000 tonnes (50,000 short tons) per year being produced during the early 1990s, [5] but is occasionally also used as a solvent.
Acrylonitrile butadiene styrene. Acrylonitrile butadiene styrene ( ABS) ( chemical formula (C 8 H 8) x · (C 4 H 6) y · (C 3 H 3 N) z ) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F). [ 4] ABS is amorphous and therefore has no true melting point. ABS is a terpolymer made by polymerizing ...
Malonic acid ( IUPAC systematic name: propanedioic acid) is a dicarboxylic acid with structure CH 2 (COOH) 2. The ionized form of malonic acid, as well as its esters and salts, are known as malonates. For example, diethyl malonate is malonic acid's diethyl ester. The name originates from the Greek word μᾶλον ( malon) meaning 'apple'.
The FCC features more than 1,250 monographs, including food-grade chemicals, processing aids, foods (such as vegetable oils, fructose, whey, and amino acids ), flavoring agents, vitamins, and functional food ingredients (such as lycopene, olestra, and short chain fructooligosaccharides ). The FCC also contains ingredients, such as sucrose and ...
3O−. 2. The neutral molecules formed by the combination of the acetate ion and a positive ion (called a cation) are also commonly called "acetates" (hence, acetate of lead, acetate of aluminium, etc.). The simplest of these is hydrogen acetate (called acetic acid) with corresponding salts, esters, and the polyatomic anion CH.
