Aludels, in ancient chemistry, are subliming pots. The term refers to a range of earthen tubes, or pots without bottoms, fitted one over another, and diminishing as they advance towards the top. The lowest is adapted to a pot, placed in a furnace, wherein the matter to be sublimed is lodged. At the top is a head to retain the flowers, or condensation, which ascends. ...more on Wikipedia about "Aludel"
Amide hydrolysis involves the C-N bond being broken in reaction with water ( hydrolysis). The reaction is catalysed by either acid or alkali. ...more on Wikipedia about "Amide hydrolysis"
(Anodising) Anodising, or anodizing, is a process used to protect aluminum from abrasion and corrosion and to allow it to be dyed in a wide range of colors. The process derives its name from the fact that the part to be treated forms the anode portion of an electrical circuit in this electrolytic process. ...more on Wikipedia about "Anodising"
Atom economy describes the conversion efficiency of a chemical process in terms of all atoms involved. In an ideal chemical process the amount of starting materials or reactants equals the amount of all products generated (see stoichiometry) and no atom is wasted. Recent developments like the advent of Green chemistry and high raw material ( oil) prices increasingly demand high atom economy. ...more on Wikipedia about "Atom economy"
A single chemical reaction is said to have undergone autocatalysis, or be autocatalytic, if the reaction product is itself the catalyst for that reaction. ...more on Wikipedia about "Autocatalysis" Must see shortopedia Chemical_processes
AVLIS Is an acronym which stands for atomic vapor laser isotope separation and is a method by which specially tuned lasers are used to separate isotopes of uranium using selective ionization of hyperfine transitions. ...more on Wikipedia about "AVLIS"
The Bayer process is the principal industrial means of producing alumina, itself important in the Hall-Héroult process for producing aluminum. ...more on Wikipedia about "Bayer process"
Bog iron refers to impure iron deposits that develop in bogs or swamps by the chemical or biochemical oxidation of iron carried in the solutions. ...more on Wikipedia about "Bog iron"
Bubble wash is a method of final washing of home-made biodiesel through air agitation. Biodiesel floats above a quantity of water. Bubbles from an aquarium air pump and air stone are injected into the water causing the bubbles to rise. At the water/biodiesel interface, the air bubbles carry water up through the biodiesel by surface tension. Diffusion causes water soluble impurities in the biodiesel to be extracted into the water. As the bubble reaches the surface and breaks, the water is freed and percolates back down through the biodiesel again. ...more on Wikipedia about "Bubble wash"
The Burton process is a thermal cracking process invented by William M. Burton; the oil industry first used it to double the production of gasoline in 1913. This thermal cracking process was patented on January 7 1913 (Patent No. 1,049,667). In 1937 it was superseded by catalytic cracking. ...more on Wikipedia about "Burton process"
Calcination is the process of heating a substance to a high temperature, but below its melting or fusing point, to bring about thermal decomposition or a phase transition in its physical or chemical constitution. The process, which usually takes place in long cylindrical kilns, often has the effect of making a substance friable. ...more on Wikipedia about "Calcination"
Carbonation occurs when carbon dioxide is dissolved in water or an aqueous solution. This process is generally represented by the following reaction, where water and gaseous carbon dioxide react to form a dilute solution of carbonic acid. ...more on Wikipedia about "Carbonation" You are visiting www.shortopedia.com
Carbonization is the term for the conversion of an organic substance into carbon or a carbon-containing residue. It is often used in organic chemistry with reference to the generation of coal gas and coal tar from raw coal. Fossil fuels in general are the products of the carbonization of vegetable matter. ...more on Wikipedia about "Carbonization"
Cathodic protection (CP) is a technique to control the corrosion of a metal surface by making that surface the cathode of an electrochemical cell. ...more on Wikipedia about "Cathodic protection"
Charring is a process of incomplete combustion that often occurs when biological tissue (living or dead) is subjected to heat. The resulting matter is sometimes called char. Coal and charcoal are produced this way. ...more on Wikipedia about "Charring"
In chemistry a chemical transformation shows the conversion of a substrate to a product omitting the reagents and catalysts or underlying reaction mechanism as opposed to a chemical reaction. The phrase Chemical transformation is used in a more general sense when reaction specifics are not relevant or not available. ...more on Wikipedia about "Chemical transformation"
Chemical vapor deposition (CVD) is a chemical process for depositing thin films of various materials. In a typical CVD process the substrate is exposed to one or more volatile precursors, which react and/or decompose on the substrate surface to produce the desired deposit. Frequently, volatile byproducts are also produced, which are removed by gas flow through the reaction chamber. ...more on Wikipedia about "Chemical vapor deposition"
Chemical-mechanical planarization or Chemical-mechanical polishing, commonly abbreviated CMP, is a technique used in semiconductor fabrication for planarizing the top surface of an in-process semiconductor wafer or other substrate. ...more on Wikipedia about "Chemical-mechanical planarization"
The chloralkali process is a redox reaction, an electrolysis of an aqueous solution of sodium chloride (salt): ...more on Wikipedia about "Chloralkali process"
Chrome plating is a finishing treatment utilizing the electrolytic deposition of chromium. The most common form of chrome plating is the thin, decorative bright chrome, which is typically a 10 µm layer over an underlying nickel plate. It imparts a mirror-like finish to items such as metal furniture frames and automotive trim. Thicker deposits, up to 1000 µm, are called hard chrome and are used in industrial equipment to reduce friction and wear and to restore the dimensions of equipment that has experienced wear. ...more on Wikipedia about "Chrome plating"
A coating is a covering that is applied to an object to protect it or change its appearance. They may be applied as liquids, gases or solids. ...more on Wikipedia about "Coating"
Combustion or burning is a chemical process, an exothermic reaction between a substance (the fuel) and a gas (the oxidizer), usually O2, to release heat. In a complete combustion reaction, a compound reacts with an oxidizing element, and the products are compounds of each element in the fuel with the oxidizing element. For example: ...more on Wikipedia about "Combustion"
The contact process is the current method of producing sulfuric acid in the high concentrations needed for industrial processes. Vanadium(V) oxide is the catalyst employed. ...more on Wikipedia about "Contact process"
