LIQUID CHELATING AGENT

Neocrys Chelate as Liquid Chelating Agent

Metal ions have a powerful influence on chemical processes as well as on the performance of many products. A wide range of problems associated with metal ions can be solved using Neocrys Chelate.

Chelates seize a metal ion and control it, making it very difficult for another substance to liberate it. NEOCRYS chelates form strong, water-soluble complexes that prevent undesirable precipitation, dissolve scale deposits and optimize oxidation processes. Our NEOCRYS chelate product range includes chelating agents that bind and control metal ions, as well as metal chelates.

• building applications
• polymer production
• pulp and paper production

3. Preventing precipitation and controlling metal catalyzed reactions

DIRECTIONS FOR USE :
The following recommendation may serve as a guide 0.5 ~ 1 G/Lt.
The quantity of chelating agent needed depends on the concentration of metal ion to be chelated and the type of NEOCRYS chelating agent used. NEOCRYS® chelating agents form a complex with a metal ion generally on an equimolecular basis (which means the higher the molecular weight of the chelating agent, the higher the quantity of chelating agent required to chelate the metal ion).

APPLICATIONS USED :
Cleaning and Detergents
NEOCRYS chelating agents are powerful builders. They enhance the cleaning power of a cleaner/ detergent by catching the hardwater ions ( Ca and Mg) and removing Ca and Mg based residues which bind most dirt to surfaces.
They also prevent the deactivation of anionic surfactants from hard water metal ions, so less surfactant can be used.
Besides this, what’s more, NEOCRYS chelating agents deactivate the unwanted transition metal ions that are often introduced through raw materials in the manufacture of soap and of detergents that contain peroxides like hydrogenperoxide, percarbonates and perborates.
In biocidal detergents chelates greatly enhances the effectiveness of biocides so the amount needed to be effective can be reduced. They also boost the performance of preservatives in liquid detergents, again less can be used and cost savings can be made.

Industrial Cleaning 
Metal salts can cause scaling problems in boilers, heat exchangers and other water circulation systems found in the power, brewing, sugar and dairy industries. NEOCRYST® chelating agents form stable, water-soluble metal complexes with all potentially harmful metal ions, dissolving existing scale formations and preventing new scales from forming.

Printing ink 
Metal ions can cause the formation of insoluble resin soaps in water thinned inks. For example, in offset printing, the formation of polyvalent metal soaps may cause unwanted discoloration. NEOCRYS® chelating agents are used to overcome these problems, resulting in clear and color-stable inks.

Pulp and paper 
Some transition metal ions catalyze the decomposition of bleaching agents (e.g. peroxide, ozone and hydrosulfite) and can lead to brightness reversion of pulp and paper. Traces of heavy metals, which occur naturally in wood fibers and processing water, work against the best efforts of pulp and paper mills to produce brighter, whiter papers. Uncontrolled, these metal ions reduce the effectiveness of hydrosulfite and hydrogen peroxide bleaches used to brighten pulps. As a result, it takes more bleach to achieve and maintain the desired level of brightness. Because bleach chemicals are relatively expensive, pulp and paper mills have long worked to control metal ions through chelation chemistry.
NEOCRYS® chelating agents are used to remove and deactivate metal ions.

Textiles 
During the scouring and bleaching of textile fibers, NEOCRYS® chelating agents remove and deactivate metal ions that would otherwise catalyze the decomposition of the peroxide bleaching agent. They also improve the performance of dye baths, where metal ions like Ca and Mg inhibit dye penetrating the fiber.

EDTA as Chelating Agent

Chelation is a chemical combination with a metal in complexes in which the metal is part of a ring. Organic ligand is called chelator or chelating agent, the chelate is a metal complex. The larger number of ring closures to a metal atom is the more stable the compound. 

This phenomenon is called the chelate effect; it is generally attributed to an increase in the thermodynamic quantity called entropy that accompanies chelation. The stability of a chelate is also related to the number of atoms in the chelate ring. 

Monodentate ligands which have one coordinating atom like H2O or NH3 are easily broken apart by other chemical processes, whereas polydentate chelators, donating multiple binds to metal ion, provide more stable complexes. Chlorophyll, green plant pigment, is a chelate that consists of a central magnesium atom joined with four complex chelating agent (pyrrole ring). The molecular structure of the chlorophyll is similar to that of the heme bound to proteins to form hemoglobin, except that the latter contains iron(II) ion in the center of the porphyrin. Heme is an iron chelate. 

 Chelation is applied in metal complex chemistry, organic and inorganic chemistry, biochemistry, and environment protection. It is used in chemotherapeutic treatments for metal poisoning. Chelating agents offers a wide range of sequestrants to control metal ions in aqueous systems. By forming stable water soluble complexes with multivalent metal ions, chelating agents prevent undesired interaction by blocking normal reactivity of metal ions. EDTA (ethylenediamine tetraacetate) is a good example of common chelating agent which have nitrogen atoms and short chain carboxylic groups. The sodium salt of EDTA is used as an antidote for metal poisoning, an anticoagulant, and an ingredient in a variety of detergents. 

 Chelating agents are important in the field of soap, detergents, textile dyeing, water softening, metal finishing and plating, pulp and paper, enzyme deactivation, photo chemistry, and bacteriocides.

APPLICATIONS
Photography, Detergent, Chemical plating, Electroplating without cyanide, cleaning agent, plastic additives, printing of cotton and chemical fiber, industrial desulfation, inhibitor for plant growth, printing ink, medicine, paper and food industry. Water treatment chemical, Agriculture
