|Section2= |Section3= |Section4= }} γ-Valerolactone (GVL) is an organic compound with the formula C5H8O2. This colourless liquid is one of the more common lactones. GVL is chiral but is usually used as the racemate. It is readily obtained from cellulosic biomass and is a potential fuel and green solvent. GVL behaves as a prodrug to γ-hydroxyvaleric acid (GHV), a drug with similar effects to those of γ-hydroxybutyric acid (GHB), albeit with less potentcy in comparison. Because GHB is controlled in many parts of the world, while GVL is not, GVL has gained popularity as a legal substitute for GHB.〔 ==Synthesis== GVL is produced from levulinic acid, which is obtained from hexoses. In a typical process, cellulosic biomasses, such as corn stover, sawgrass, or wood, is hydrolysed into glucose and other sugars using acid catalysts. The resulting glucose can then be dehydrated via hydroxymethylfurfural to yield formic acid and levulinic acid, which can then be hydrogenated to gamma-hydroxypentanoic acid, which readily cyclises to ''gamma''-valerolactone, which has potential applications as a liquid fuel. :File:Cyclization of levulinic acid.svg 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gamma-Valerolactone」の詳細全文を読む スポンサード リンク
