|Section2= |Section3= |Section4= |Section5= }} 2-Ethylhexanoic acid is the organic compound with the formula CH3(CH2)3CH(C2H5)CO2H. This carboxylic acid is widely used to prepare metal derivatives that are soluble in nonpolar organic solvents. These lipophilic metal-containing derivatives are used as catalysts in polymerizations. For example, tin 2-ethylhexanoate is used in the production of poly(lactic-co-glycolic acid). The high solubility of these metal complexes is attributable to the long hydrocarbon chain and the presence of a chiral center which leads to mixtures of enantiomeric complexes. These metal complexes are often described as salts, when in fact they are not ionic but charge-neutral coordination complexes akin to the better defined, more crystalline acetates. ==Examples of metal ethylhexanoates== * Hydroxyl aluminium bis(2-ethylhexanoate), used as a thickener * Tin(II) ethylhexanoate (CAS# 301-10-0), a catalyst for polylactide polymerization * Cobalt(II) ethylhexanoate (CAS# 136-52-7), a drier for alkyd resins * Nickel(II) ethylhexanoate (CAS# 4454-16-4) 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「2-Ethylhexanoic acid」の詳細全文を読む スポンサード リンク
