Latest Patents
Kupper's latest patents include a method of manufacturing ortho-substituted alkylphenols. This method employs a catalyst of increased activity, allowing for the reaction of phenol or 2-alkylphenols with 2-alkyl-1-alkenes and/or 2-aryl-1-alkenes in the liquid phase. The process can be conducted in the presence of inert diluents and/or an excess of the alkene. The reaction utilizes modified aluminum-containing catalysts, which are enhanced by adding small amounts of polyhalophenols. These cocatalysts contain at least three halogen substituents from the elements fluorine, chlorine, and bromine. The molar ratio between the cocatalysts and the aluminum compound ranges from 0.5:1 to 8:1. Another significant patent involves a method for the cyclooligomerization of 3-hydroxy-1-alkynes, particularly focusing on the cyclooligomerization of 3-methyl-1-butyne-3-ol to yield 1,3,5-tris(.alpha.-hydroxyisopropyl)-benzene. This method utilizes nickel-containing catalysts formed from a nickel compound, a phosphite of an ortho-substituted phenol, and an organoaluminum compound.
