| titleOfInvention | Method for producing d, 1-α-tocopherol |
| abstract | (57) [Summary] A method for producing d, l-α-tocopherol by catalytic condensation of trimethylhydroquinone with isophytol is described by using bis- (trifluoromethylsulfonyl) amine [HN (SO 2 CF 3 ) 2 ] as a catalyst. Or the formula: Met [N (SO 2 CF 3 ) 2 ] n (I) wherein Met is lithium, boron, magnesium, aluminum, silicon, scandium, titanium, vanadium, manganese, iron, cobalt, nickel, Represents a metal atom selected from the group of copper, zinc, yttrium, zirconium, rhodium, palladium, silver, tin, lanthanum, cerium, neodymium, praseodymium, europium, dysprosium, ytterbium, hafnium, platinum, and gold, and n is Which represents the corresponding valence (1, 2, 3 or 4) of the metal atom Met] Presence of Shokushio, or the presence of a combination of metal salt and a strong Bronsted acid of the formula (I) as the catalyst system, perform the condensation in an organic solvent. The products of this method are the most active members of the vitamin E group. |
