|Section2= |Section7= }} Quinaldine or 2-methylquinoline is a simple derivative of a heterocyclic compound quinoline. Quinaldine has critical point at 787 K and 4.9 MPa and its refractive index is 1.8116. It can be prepared from aniline and paraldehyde via Skraup synthesis or from aniline and crotonaldehyde via Doebner-von Miller variation of the Skraup reaction〔(Classical methods of synthesizing quinolines )〕 or extracted from coal tar. ==Uses== Quinaldine is used in anti-malaria drugs, in manufacturing dyes, food colorants (e.g. Quinoline Yellow WS), pharmaceuticals, pH indicators. Quinaldine sulfate is an anaesthetic used in fish transportation. In some Caribbean islands it is used to facilitate the collection of tropical fish from reefs. 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「Quinaldine」の詳細全文を読む スポンサード リンク
