123-28-4 Usage

Appearance

White to Almost white powder to crystal

Uses

Different sources of media describe the Uses of 123-28-4 differently. You can refer to the following data:
1. Dilauryl Thiodipropionate (DLTDP) is an antioxidant that exists as white crystalline flakes of sweetish ester-like odor. It is insoluble in water but soluble in inorganic solvents. It is used in fats and oils to prevent rancidity. It is used in food when the total antioxidant content is not over 0.02% of the fat or oil content.
2. Didodecyl 3,3'-Thiodipropionate is an antioxidant used as a modifier to stabilize acrylonitrile-butadiene-styrene (ABS) graft copolymers due to a strong synergistic effect. This substance is used by consumers, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites and in manufacturing.
3. Didodecyl 3,3''-Thiodipropionate is an antioxidant used as a modifier to stabilize acrylonitrile-?butadiene-?styrene (ABS) graft copolymers due to a strong synergistic effect.

Flammability and Explosibility

Nonflammable

Safety Profile

An eye irritant. When heated to decomposition it emits toxic fumes of SOx.

Check Digit Verification of cas no

The CAS Registry Mumber 123-28-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123-28:
(5*1)+(4*2)+(3*3)+(2*2)+(1*8)=34
34 % 10 = 4
So 123-28-4 is a valid CAS Registry Number.

Dialkyl 3,3′-thiodipropionate and dialkyl 2,2′-thiodiacetate antioxidants by lipase-catalyzed esterification and transesterification

Weber, Nikolaus,Klein, Erika,Vosmann, Klaus

, p. 2957 - 2963 (2007/10/03)

Medium- and long-chain dialkyl 3,3′-thiodipropionate antioxidants such as dioctyl 3,3′-thiodipropionate, didodecyl 3,3′- thiodipropionate, dihexadecyl 3,3′-thiodipropionate, and di-(cis-9-octadecenyl) 3,3′-thiodipropionate were prepared in high yield by lipase-catalyzed esterification and transesterification of 3,3′-thiodipropionic acid and its dimethyl ester, respectively, with the corresponding medium- or long-chain 1-alkanols, i.e., 1-octanol, 1-dodecanol, 1-hexadecanol, and cis-9-octadecen-1-ol, in vacuo (80 kPa) at moderate temperatures (60-80°C) without solvents. Immobilized lipase B from Candida antarctica (Novozym 435) was the most active biocatalyst for the preparation of medium- and long-chain dialkyl 3,3′-thiodipropionates showing enzyme activities up to 1489 units/g, whereas the immobilized lipases from Rhizomucor miehei (Lipozyme RM IM) and Thermomyces lanuginosus (Lipozyme TL IM) were by far less active (~10 enzyme units/g). Maximum conversions to dialkyl 3,3′-thiodipropionates were as high as 92-98% after 4 h of reaction time. Similarly, dihexadecyl 2,2′-thiodiacetate was prepared in high yield using 2,2′-thiodiacetic acid or diethyl 2,2′-thiodiacetate and 1-hexadecanol as the starting materials and Novozym 435 as the biocatalyst.

Stabilizer for synthetic resins

-

, (2008/06/13)

Synthetic resins, particularly polyolefins, are markedly improved in their resistances to heat and oxidation by the incorporation of a 2-methyl-4-t-butyl-5-hydroxyphenylalkanoic acid ester alone or in combination with a thioether-type antioxidant represented by the general formula STR1 wherein R represents an alkyl group of 12 to 20 carbon atoms, or by the general formula STR2 wherein R represents an alkyl group of 4 to 20 carbon atoms.
