Abstract:
The present invention relates to a crystalline form of antioxidant 1035 and a method for producing the same, which are defined by the diffraction angle 2 & theta;° of the X-ray powder diffraction pattern and the characteristic peak of DSC. The antioxidant 1035 solid is added to the organic solvent to prepare a suspension of 0.3~0.6g/mL, the solid is completely dissolved at 45~60 ℃, and the temperature is reduced to 30~40 ℃, seed crystals were added to the solution, and then the temperature was cooled to 5-15 ° C., and the resulting suspension was suction filtered to obtain a wet product, which was dried to constant weight under normal pressure. Dry the antioxidant 1035 wet crystalline product to constant weight to give the final antioxidant 1035 New crystalline product. The new crystalline product has lower melting and melting point, higher solubility, higher bulk density and better flowability, so it is easier to implement on a commercial scale.
Abstract:
Antioxidant 2,2 '-thiodiethyl BIS [3-(3, 5-di-tert-butyl-4-hydroxyphenyl) propionate] (abbreviation: antioxidant 1035), it is a kind of thiophenol compound, which belongs to the intramolecular compound antioxidant. It has the function of capturing the peroxide free radicals in the polymer, and can decompose the hydroperoxide. With the hindered phenolic main antioxidant, phosphite auxiliary antioxidant, has good synergistic effect; Β-(3, 5-di-tert-butyl-4-hydroxyphenyl) propionic acid isooctyl alcohol ester (abbreviation: antioxidant 1135), is a kind of weight... see all
