Title: Process for producing ª‡-tocopherol having a high vitamin e activity
IPC: C07D311/72
Filed: 1964-09-28
Abstract: a -Tocopherol is obtained from non-a -tocopherols having at least one hydrogen atom in the benzene nucleus by hydroxymethylating said hydrogen atom or atoms with formaldehyde in the presence of boric acid, and then reducing the hydroxymethyl group, or groups to a methyl group or groups.  The hydroxymethylation may be carried out in a solvent using paraformaldehyde or aqueous formaldehyde solution. The hydroxymethyl radicals may be reduced to methyl radicals with zinc and hydrochloric acid, with a zinc-mercury amalgam and an inorganic acid, or by catalytic hydrogenation with a nickel or palladium catalyst.  In an example, the source of non-a -tocopherols is soybean oil.
