|Section2= |Section4= }} 3-Hydroxypropionic acid is a carboxylic acid, specifically a beta hydroxy acid. It is an acidic viscous liquid with a pKa of 4.5.〔 It is very soluble in water, soluble in ethanol, and miscible with diethyl ether. Upon distillation, it dehydrates to form acrylic acid. 3-Hydroxypropionic acid is used in the industrial production of various chemicals such as acrylates. It can be produced by engineered microbes.〔()〕 ==Applications in producing a biodegradable polymer== A method has been developed by the University of Minnesota to produce a biodegradable polymer polyester known as poly(3-hydroxypropionic acid).〔(【引用サイトリンク】url=http://www.license.umn.edu/Products/Biodegradable-Polyester-Produced-From-Non-toxic--Renewable-Monomer__Z05135.aspx )〕 The method combines the high-molecular weight and control aspects of ring-opening polymerization with the commercial availability of the beta hydroxy acid, 3-hydroxypropionic acid which is abbreviated as 3-HP. Since 3-HP can be derived from biological sources, the resulting material, poly(3-hydroxypropionic acid) or P(3-HP), is biorenewable. The new method allows direct synthesis of the bio-based polymer P(3-HP) from 3-HP, a commercial monomer that is derived from corn. The method uses a single vessel reactor for simple synthesis and rapid scale up. The method results in a higher molecular weight which makes the polymer more structurally sound using a process with lower toxicity than competing technologies. 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「3-Hydroxypropionic acid」の詳細全文を読む スポンサード リンク
