off-white crystalline solid | [Uses]
vitamin E | [General Description]
Odorless off-white crystals. Darkens at 401° F. | [Reactivity Profile]
An ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. | [Air & Water Reactions]
This chemical may be sensitive to prolonged exposure to light and air. . Insoluble in water. | [Fire Hazard]
Flash point data for this chemical are not available. D-ALPHA-TOCOPHERYL ACETATE is probably combustible. | [Definition]
ChEBI: Alpha-Tocopherol acetate is a tocol. | [Biochem/physiol Actions]
α-Tocopherol acetate or vitamin E-acetate has antioxidant properties and reduces lipid peroxidation. However, vitamin E acetate on pyrolysis leads to the generation of carcinogens like alkenes and benzenes. | [Synthesis]
A method of preparing vitamin E acetate, characterized in that it comprises the steps of:
(1) add 2,3,5-trimethylhydroquinone and catalyst composed of concentrated sulfuric acid, copper sulfate, tin chloride to the reaction solvent, stir until |
