Product Name:Dilauryl thiodipropionate
English Name:Dilauryl thiodipropionate
CAS No.:123-28-4
Aliases:DLT, DLTP, DLTDP, Dilauryl 3,3'-thiodipropionate
Molecular Formula:C30H58O4S
Physical Properties:White flaky crystals with a molecular weight of 514.9 and a crystallization point of 39.5-41.5°C. Insoluble in water, soluble in organic solvents such as acetone, carbon tetrachloride, benzene, and petroleum ether. At 20°C, the solubility is 20 g/100 g solvent in acetone, 100 g/100 g in carbon tetrachloride, 133 g/100 g in benzene, and 40 g/100 g in petroleum ether.
Uses:This product is an excellent auxiliary antioxidant, widely used in synthetic materials such as polypropylene, polyethylene, ABS, and PBT, as well as in rubber processing and lubricating greases. It is often combined with phenolic primary antioxidants to produce a synergistic effect, significantly enhancing the antioxidant performance and improving the processing properties and service life of products. Due to its extremely low toxicity, it can also be used in food packaging films and as an antioxidant for fatty foods, edible oils, and a freshness preservative for fruits and vegetables, with a maximum usage level of 0.2 g/kg.
