Uses
Different sources of media describe the Uses of 2082-79-3 differently. You can refer to the following data:
1. 1076 is a nonpolluting nontoxic antioxidant with good heat-resisting and water-extracting performance. It can be applied in polyolefins, such as polyeth-ylene, polypropylene, polybutene-1 and other polymers such as engineering plastics ,styrenes, polyurethanes, saturated and unsaturated elastomers, styrenics, rubber modified styrenics, segmented block copolymers, and PVC. Also often used with DLTDP for promoting the antioxidative effect.
2. Octadecyl 3-?(3,?5-?Di-?tert-?butyl-?4-?hydroxyphenyl)?propionate is a 4 chain-breaking antioxidant. A study shows that Octadecyl 3-?(3,?5-?Di-?tert-?butyl-?4-?hydroxyphenyl)?propionate can protect the oxidation of soybean phosphatidylcholine liposomes in water dispersion, but cannot protect the oxidation of dimyristoyl phosphatidylcholine liposomes.
Application
Antioxidant 1076 finds application in plastics, rubber, latex, varnishes, adhesives, TPR's and Hot
Melts. In plastics, antioxidant 1076 provides excellent antioxidant performance in Polyethylene,
Polystyrene, Polyacetal, PVC, AS resin, Methacrylic resin, Polycarbonate, Polyester, and Polymethyl-
pentene as well as many others. In rubbers, Antioxidant 1076 can be used in SBR, EPR, EPDM,

Check Digit Verification of cas no
The CAS Registry Mumber 2082-79-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,8 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2082-79:
(6*2)+(5*0)+(4*8)+(3*2)+(2*7)+(1*9)=73
73 % 10 = 3
So 2082-79-3 is a valid CAS Registry Number.

Page/Page column 3-4, (2010/08/22)
A method for making a hindered phenolic antioxidant based on Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate uses a methanol solution containing alkali metal methoxide as a catalyst solution, wherein the catalyst solution is filtered with a filter device with a filter pore diameter of less than 50 μm to remove insoluble matters therefrom before used in a transesterification process where methyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate and 1-Octadecanol are taken as reactants to obtain a crude product of Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate having high conversion rate and low color, and the crude product further undergoes a purification process for crystallization, filtering and drying to obtain a product of Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate having high purity and low color.
