6683-19-8 Usage
Characterization
Antioxidant 1010– a sterically hindered phenolic antioxidant – is a highly effective, non discoloring stabilizer for organic substrates such as plastics, synthetic fibers, elastomers, adhesives, waxes, oils and fats. It protects these substrates against thermo-oxidative degradation.
Application
Antioxidant 1010 can be applied in polyolefins, such as polyethylene, polypropylene, polybutene and olefin copolymers such as ethylene-vinylacetate copolymers. Also, its use is recommended for the processing of polymers such as polyacetals, polyamides and polyurethanes, polyesters, PVC, styrene homo- and copolymers, ABS, elastomers such as butyl rubber (IIR), SBS, SEBS, EPM and EPDM as well as other synthetic rubbers, adhesives, natural and synthetic tackifier resins, and other organic substrates.
Features/benefits
Antioxidant 1010 has good compatibility, high resistance to extraction and low volatility. It is odorless and tasteless. The product can be used in combination with other additives such as costabilizers (e. g. thioethers, phosphites, phosphonites), light stabilizers and other functional stabilizers.
Health & Safety
Antioxidant 1010 exhibits a very low order of oral toxicity and does not present any abnormal problems in its handling or general use.

Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 6683-19-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,8 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6683-19:
(6*6)+(5*6)+(4*8)+(3*3)+(2*1)+(1*9)=118
118 % 10 = 8
So 6683-19-8 is a valid CAS Registry Number.

The transesterification of methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propanoate with tetrakis(hydroxymethyl)methane depends on the equilibrium constants of the reversible reactions; for the final step, the equilibrium constant is K 1. The molecular geometries and the enthalpies and entropies of the equilibrium reactions were calculated by the semiempirical PM6 quantum chemical method. The thermodynamic equilibrium constants of the reversible reactions were calculated by the Boltzmann equation from the Gibbs energies G f ○. For tris-[3-(3,5-di-tert-butyl-4-hydroxyphenyl) propanoyloxymethyl](hydroxymethyl)methane, the dipole moment is μ = 0.97 D and the energy of the O-H homolysis is D OH = 347.3 kJ mol -1. For tetrakis[3-(3,5-di-tert-butyl-4-hydroxyphenyl) propanoyloxymethyl]methane, μ is 5.6 D and D OH is 321 kJ mol -1. The geometry of the structure affects the H-O homolysis energy and the chain termination coefficient under the conditions of inhibited cumene oxidation.
