It is a white, odorless solid. Succinate plays a role in the citric acid cycle, an energy-yielding process. The name derives from Latin ''succinum'', meaning amber, from which the acid may be obtained. ==Production and reactions== Spirit of amber was originally obtained from amber by pulverising and distilling it using a sand bath. Succinic acid is produced by several methods. Common industrial routes include hydrogenation of maleic acid, oxidation of 1,4-butanediol, and carbonylation of ethylene glycol. More recently, succinic acid has been produced through the fermentation of glucose from renewable feedstock and purification of raw bio-based succinic acid.〔(【引用サイトリンク】title=Life Cycle Analysis (LCA) )〕 Succinic acid can be converted into fumaric acid by oxidation. The diethyl ester is a substrate in the Stobbe condensation. Dehydration of succinic acid gives succinic anhydride.〔.〕 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「succinic acid」の詳細全文を読む スポンサード リンク
