Triallyl Cyanurate [CAS: 101-37-1]

1.Specifiaction （ Viscosity[Cp(30℃)] 12.5 ）

Product Name Triallyl cyanurate (TAC)

CAS No 101-37-1

Appearance Transparent liquid or Solid

Assay ≥99.0%

Melting Point ≥ ℃ 25 ℃

Color( Garde Liquid color standard) ≤ 5%

Moisture ≤ 0.4%

Toluene ≤ 0.2%

2. Properties

TAC is a trifunctional monomer which can easily polymerize especially in the presence of peroxide

catalysts. It is hydrolyzed by mineral acids under formation of allyl alcohol and cyanuric acid. Also

in strong alkaline medium it is decomposed easily.

3. Application

TAC is used as coagent in peroxide crosslinking of elastomers like HNBR, EPM, EPDM, EVA, CR,

TPE´s and of thermoplastics like PE and PVC. It can also be employed as coagent for electron

beam crosslinking of PE and TPE´s. TAC reduces cure times, it increases the crosslinking density,

leads to a lower compression set and improved aging properties. Typical products are:

- pipes and hoses

- sealings and gaskets

- damping materials

- cable coatings

- electronical components

- foams and shoe soles

- EVA encapsulating films for solar panels

4. Handling and Storage

TAC has a low acute toxicity. For handling regular personal protection equipment is

recommended (for details see our MSDS). If the material has to be remelted we recommend a

water bath with a maximum temperature of 50°C. Also drying chambers can be used, if the

temperature is controlled carefully. Store under cool (<40°C) and dry conditions. Although the

product is stabilized, we recommend the use TAC within 18 months. After longer storage times

turbidity by oligomeric material can be obtained.

5. Packaging: 200kg/Drum, 4 drums/Pallet

Buchwald Hatwig Amination Reaction and The Phosphine Ligands

The Buchwald–Hartwig amination is a chemical reaction used in organic chemistry for the synthesis of carbon–nitrogen bondsvia the Palladium-catalyzed coupling reactions of amines with aryl halides. Although Pd-catalyzed C-N couplings were reported as early as 1983, Stephen L. Buchwald and John F. Hartwig have been credited, whose publications between 1994 and the late 2000s established the scope of the transformation. The reaction's synthetic utility stems primarily from the shortcomings of typical methods (nucleophilic substitution, reductive amination, etc.) for the synthesis of aromatic C–N bonds, with most methods suffering from limited substrate scope and functional group tolerance. The development of the Buchwald–Hartwig reaction allowed for the facile synthesis of aryl amines, replacing to an extent harsher methods (the Goldberg reaction, nucleophilic aromatic substitution, etc.) while significantly expanding the repertoire of possible C–N bond formation.

Enantioselective catalysis

In general, enantioselective catalysis (known traditionally as asymmetric catalysis) are chiral coordination complexes. Catalysis is effective for a broader range of transformations than any other method of enantioselective synthesis. The catalysts are almost invariably rendered chiral by using chiral ligands (it is also possible to generate chiral-at-metal complexes using simpler achiral ligands, but such species have rarely proven to be useful synthetically). Most enantioselective catalysts are effective at low substrate/catalyst ratios. Given their high efficiencies, they are often suitable for industrial scale synthesis, even with expensive catalysts. A versatile example of enantioselective synthesis is asymmetric hydrogenation, which is used to reduce a wide variety of functional groups.

The design of new catalysts is very much dominated by the development of new classes of ligands. Certain ligands, often referred to as 'privileged ligands', have been found to be effective in a wide range of reactions; examples include BINOL, Salen, and BOX. In general however few catalysts are effective at more than one type of asymmetric reaction. For example, Noyori asymmetric hydrogenation with BINAP/Ru requires a β-ketone, although another catalyst, BINAP/diamine-Ru, widens the scope to α,β-alkenes and aromatic chemicals.
