Methanesulfonates of saturated and unsaturated long-chain alcohols are conveniently obtained in good purity and high yields. They can be converted, quantitatively, to hydrocarbons by reduction with lithium aluminum hydride. The procedure is applicable to the preparation of alkanes and alkenes, cis,
## The use of lower-order models in obtaining approximate solutions in optimal control problems has been of much interest during the past few years. Two new procedures for order reduction, based on interpreting the system impulse response (or transfer function) as an input-output map, are presented.
