NOVELTY - Preparing an unsaturated alcohol composition, comprises: (a) reacting a metathesis-derived hydrocarbyl carbonyl compound in the presence of a silane compound, an organic solvent, and a catalyst system prepared from a metallic complex and a reducing agent; (b) hydrolyzing the mixture from step (a) with a metallic base, and then adding an organic solvent; and (c) separating, washing, drying and/or purifying, as individual steps or in combinations, the mixture of step (b) to produce the unsaturated alcohol composition.    USE - The process is useful for preparing an unsaturated alcohol composition including 9-decen-1-ol (preferred) or 9-dodecen-1-ol, which is useful for making a derivative, where the derivative is useful in a synthetic base stock (all claimed) for preparing e.g. lubricants, functional fluids, fuels, functional additives for such lubricants, functional fluids and fuels, plasticizers, asphalt additives, friction reducing agents, plastics, and adhesives, and in friction reducing agents, corrosion inhibitors, pigment wetting agents, in cleaning compositions and skin feel agents, an in personal care products (e.g. bar soaps, bubble baths, shampoos, conditioners and body washes), household products (e.g. carpet cleaners, fabric softeners and laundry additives) and industrial and institutional cleaning products, oil field applications, and agricultural formulations.    ADVANTAGE - The process provides unsaturated alcohol composition which enables shipment of more concentrated products, reduces the need for special handling equipment and/or ultimately provides substantial cost savings, when compared to the saturated fatty alcohol derivatives.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a derivative made by polymerization of a metathesis-derived unsaturated alcohol composition with an individual or mixed alpha olefin stream;    (2) a synthetic base stock, comprising the derivative; and    (3) a derivative including (a1) a derivative made by reacting a metathesis-derived unsaturated alcohol composition with one of a sulfurizing reagent, a carboxylic acid or an amine compound, (b1) a saccharide derivative made by acid-catalyzed direct glycosidation of metathesis-derived unsaturated alcohol composition, or by transglycosidation of lower polyglucosides with a metathesis-derived unsaturated alcohol composition, (c1) an alkyl glyceryl ether derivative made by the alkylation of metathesis-derived unsaturated alcohol composition with glycidol, in the presence of an acidic or alkaline catalyst, (d1) an alkyl glyceryl ether derivative made by the alkylation of metathesis-derived unsaturated alcohol composition with glycidol, in the presence of an acidic or alkaline catalyst, or (e1) a phosphoric acid mono-, di-, and tri-ester derivative made by the phosphorylation of metathesis-derived unsaturated alcohol composition using phosphorus pentoxide.
