Chelation Resource Center Chelation. Chelation is a concept from ancient times meaning “crab claw”, and in modern chemistry relates to “ligand chemistry.” Ligands are, in this application, substances that bind up toxic metals with opposite charges and carry them out of the body.

Production of a high value ceramic material: Silicon carbide The chemical reaction for the manufacture of SiC from silica (SiO 2) and carbon is written as: Beta-SiC is synthesized through the gaseous intermediate SiO(g) with the following reactions being most important: SiO(g) is initially formed at the contact points of the carbon and the silica, according to the reaction (2).owever, the earliest use of shapes was in the form of a silicon-SiC composite made by the reaction-sintering or reaction-bonding process (RBSC). Typically the SiC grains are mixed with carbon in various forms and the mixture heated in contact with molten silicon.

Ablation The term is often used in the context of laser ablation, a process in which a laser dissolves a material's molecular bonds. For a laser to ablate tissues, the power density or fluence must be high, otherwise thermocoagulation occurs, which is simply thermal vaporization of the tissues.

unimolecular reaction a reaction involving a single molecule (for example, decomposition, intramolecular rearrangement, intramolecular oxidation or reduction), even if a catalytic agent, such as acid or alkali, is present in large excess, on a molecular basis, or is not rate-determining; such reactions are usually first-order reactions.

Silica (SiO2) The Total Silica content of a water is composed of Reactive Silica and  Unreactive Silica . Reactive silica (e.g. silicates SiO4) is dissolved silica that is slightly ionized and has not been polymerized into a long chain. Reactive silica is the form that RO and ion exchange chemists hope for.Reactive silica is the form of silica to be used in RO projection programs. Reactive silica, though it has anionic characteristics, is not counted as an anion in terms of balancing a water analysis but it is counted as a part of total TDS.eactive silica (e.g. silicates SiO4) is dissolved silica that is slightly ionized and has not been polymerized into a long chain. Reactive silica is the form that RO and ion exchange chemists hope for. Reactive silica is the form of silica to be used in RO projection programs.

Definitions &Translations Alkylation. Alkylation is the transfer of an alkyl group from one molecule to another. The alkyl group may be transferred as an alkyl carbocation, a free radical, a carbanion or a carbene. Alkylating agents are widely used in chemistry because the alkyl group is probably the most common group encountered in organic molecules.

- An enzymatic process using isomerase fixated on a resin facilitates the conversion of glucose to fructose. By using more resin columns in parallel the enzyme activity is completely exhausted before a refill. The isomerase catalyses the formation of 42% fructose in equilibrium with glucose.ntermediate and higher conversion products for special purposes can also be made by substituting acid with enzymes-typically in a two step process. For the first step, the liquefaction, termostable a-amylase or acid is used. After cooling and pH adjustment a saccharification enzyme like amyloglucosidase is applied.

Alkylation In an oil refinery it is referred to as a sulfuric acid alkylation unit (SAAU) or a hydrofluoric alkylation unit, (HFAU). Refinery workers may simply refer to it as the alky or alky unit. The catalyst protonates the alkenes (propene, butene) to produce reactive carbocations, which alkylate isobutane.

Laser ablation Preparation of nanoparticles by Laser in Solution. Laser ablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser flux, the material is typically converted to a plasma.
