The present application relates to compounds and methods for reducing the severity of convulsant activity or epileptic seizures, or for the treatment of chronic or acute pain.

The present application relates to compounds and methods for reducing the severity of convulsant activity or epileptic seizures, or for the treatment of chronic or acute pain.

The present invention relates to a novel synthetic pathway for alpha-tocopherol. The invention discloses different reactions yielding some new intermediates in a very high yield and stereoselectivity.

Disclosed are processes for making cyclohexanone from a feed mixture comprising cyclohexylbenzene, cyclohexanone, phenol, 3-cylclohexenone and optionally 2-cyclohexenone, comprising feeding the feed mixture to a first distillation column and hydrogenating a fraction from the first distillation column in a hydrogenation reactor separate from the first distillation in the presence of a hydrogenation catalyst under hydrogenation conditions. A cyclohexanone-rich upper effluent comprising 3-cyclohexenone and 2-cyclohexenone at low concentrations can be obtained from the first distillation column.

Provided herein are methods for producing cyclic and acyclic ketones from trimerization and dimerization of alkyl ketones, including for example methyl ketones. Such cyclic and acyclic ketones may be suitable for use as fuel and lubricant precursors, and may be hydrodeoxygenated to form their corresponding cycloalkanes and alkanes. Such cycloalkanes and alkanes may be suitable for use as fuels, including jet fuels, and lubricants.
