2451-62-9 Usage
Industrial Application
1,3,5-triglycidyl isocyanurate (TGIC) is a white powder or granular solid and is normally sold under the trade name ARALDITE PT810R or TEPIC G R. As a tri-functional epoxy monomer, TGIC is used in large scale as curing agent for powder coatings or for cross-linking elastomers. Rosin acids of natural origin may also be cured with TGIC for versatile applications. TGIC has also been used for pharmaceutical purposes, in membranes, for curing intelligent gels or liquid crystal elastomers. Especially, this curing agent has been widely used in dry powder coating for over 40 years.
Health Toxicity
It has been known that TGIC is toxic by inhalation and if swallowed. It is a severe eye irritant, and a mild skin and nasal irritant, although it has the potential to cause skin sensitisation in people which can lead to severe skin rashes. Exposure to TGIC in powder paints may cause not only contact dermatitis, but also occupational asthma. Kidney damage has also been observed in rats repeatedly exposed to TGIC by oral dosing, and damage to the developing sperm cells has been observed in mice repeatedly exposed to TGIC orally and by inhalation. There is an evidence that exposure of males to TGIC produces genetic changes in the sperm which may lead to heritable effects in the offspring. There is cause for concern that these effects could occur in humans, so that TGIC has been classified in the EU as a Category 2 mutagen. Exposures to TGIC during manufacturing procedures have been identified as hazardous to workers.
Description
Occupational contact dermatitis can occur
in people producing this chemical, in those producing
the powder coat paint and in sprayers.
Chemical Properties
White powder or chunks
Uses
Different sources of media describe the Uses of 2451-62-9 differently. You can refer to the following data:
1. 1,3,5-triglycidyl isocyanurate be used for curing agent of polyester and acrylic resin carboxyl-containing powder coating, manufacturing an electrical insulating laminates, adhesives, plastics stabilizers.
2. TGIC is widely used as a cross-linking agent or curing agent in powder coating industry, It is used also in the printed circuit board industry, electrical insulation and as a stabilizer in plastic industry.
Typical applications of polyester TGIC powder coatings are where sharp edges and corners exist such as on automotive wheels, air conditioners, lawn furniture, and air conditioner cabinets.
3. Triglycidyl isocyanurate is used as cross-linker in heat-cured polyester paints, such as laminated sheetings, printed circuits, tools, inks, adhesives, lining materials etc.
General Description
White crystalline solid.
Air & Water Reactions
Insoluble in water.
Reactivity Profile
Epoxides are highly reactive. They polymerize in the presence of catalysts or when heated. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts.
Fire Hazard
Flash point data for 1,3,5-Triglycidyl isocyanurate are not available; however, 1,3,5-Triglycidyl isocyanurate is probably combustible.
Flammability and Explosibility
Nonflammable
Contact allergens
Triglycidyl isocyanurate is a triazine epoxy compound
used as a resin hardener in polyester powder paints, in
the plastics industry, resin molding systems, inks, and
adhesives. Occupational contact dermatitis can occur in people producing this chemical, in those producing
the powder coat paint, and in sprayers. Respiratory
symptoms have been observed.
Check Digit Verification of cas no
The CAS Registry Mumber 2451-62-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,5 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2451-62:
(6*2)+(5*4)+(4*5)+(3*1)+(2*6)+(1*2)=69
69 % 10 = 9
So 2451-62-9 is a valid CAS Registry Number.

-
Paragraph 0038-0051, (2021/02/06)
The invention relates to a preparation method of triglycidyl isocyanurate. The preparation method comprises the steps that cyanuric acid and dichloropropanol are subjected to a heating reaction in thepresence of alkali and a solvent, the molar ratio of cyanuric acid to dichloropropanol is 1: 2 to 8, and the molar ratio of the addition amount of alkali to the addition amount of dichloropropanol is2: 1. The raw material conversion rate of the triglycidyl isocyanurate prepared by the method is high and reaches 95% or above, the product selectivity is good and reaches 95% or above, and the product yield is high and reaches 90% or above and is far higher than the yield of about 80% in the prior art.

The invention provides a method for synthesizing TGIC and coproducing ECH from dichloropropanol. The method comprises the following steps: (1) proportionally adding cyanuric acid, dichloropropanol, aquaternary ammonium salt phase transfer catalyst and water, heating and stirring the mixture and carrying out temperature control reaction in stages, heating and stirring the mixture to a certain temperature, carrying out heat preservation reaction for a period of time, heating the mixture, carrying out heat preservation reaction for a period of time, and cooling a reaction product; (2) in the reaction system in the step (1), adjusting the vacuum degree, dropwise adding liquid caustic soda while carrying out steam stripping with water within a certain period of time, carrying out heat preservation reaction for a period of time after dropwise adding is finished, and then removing solid salt through plate-and-frame filter pressing; (3) carrying out reduced pressure distillation on the filtrate obtained in the step (2) to remove ECH, and collecting a crude product TGIC from the kettle liquid; (4) recrystallizing the crude product TGIC in an organic solvent for a period of time under a low-temperature condition, and then centrifugally separating, washing and drying the product to obtain a TGIC product. According to the treatment method disclosed by the invention, the cost of TGIC can be effectively reduced, an important organic chemical raw material ECH is co-produced, and the method is low-carbon and environment-friendly.
