• ether
  • A colorless liquid, slightly soluble in water; used as a reagent, intermediate, anesthetic, and solvent.
Abstract from DBPedia
    In organic chemistry, ethers are a class of compounds that contain an ether group—an oxygen atom connected to two alkyl or aryl groups. They have the general formula R−O−R′, where R and R′ represent the alkyl or aryl groups. Ethers can again be classified into two varieties: if the alkyl or aryl groups are the same on both sides of the oxygen atom, then it is a simple or symmetrical ether, whereas if they are different, the ethers are called mixed or unsymmetrical ethers. A typical example of the first group is the solvent and anaesthetic diethyl ether, commonly referred to simply as "ether" (CH3−CH2−O−CH2−CH3). Ethers are common in organic chemistry and even more prevalent in biochemistry, as they are common linkages in carbohydrates and lignin.

    エーテル(オランダ語: ether)は、有機化合物の分類のひとつで、構造式を R−O−R'(R, R' はアルキル基、アリール基などの有機基、O は酸素原子)の形で表される化合物を指す。また、エーテルに含まれる −O− の部分をエーテル結合という。また、溶媒としてのジエチルエーテルを単にエーテルということも多い。
