The present invention relates to a method for preparing saturated C.sub.n- and C.sub.2n-alcohols, wherein the ratio of C.sub.n- to C.sub.2n-alcohols is controlled by a distillative separation of the aldehydes used.

The present invention relates to a method for preparing saturated C.sub.n- and C.sub.2n-alcohols, wherein the separation of the C.sub.n-alcohols and the C.sub.2n-alcohols is effected by means of at least one two-column system or by means of at least one dividing wall 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.

The present invention is directed to inhibitors of tyrosinase, pharmaceutical compositions comprising such tyrosinase inhibitors, and methods of making and using the same. Specifically, included in the present invention are compositions of matter comprised of at least one 2,4-dihydroxybenzene analog, which inhibit the activity of tyrosinase and which inhibit the overproduction of melanin.
