amine
アミン
解説 Definition
amine は、化学でアミンという種類の化合物を指します。日本語のカタカナ語「アミン」とほぼ同じ意味で、窒素を含む有機化合物について使われます。
An amine is an organic nitrogen-containing compound formally derived from ammonia by replacing one or more hydrogen atoms with carbon-containing groups. Amines commonly act as bases and can react with acids to form salts.
覚え方のコツ Memory Tip
amine は ammonia「アンモニア」と語形・化学的概念がつながる窒素化合物です。アンモニア NH₃ の水素が有機基に置き換わった構造を思い浮かべると、アミンの核が定着します。an amine、primary amine、amine salt のように使い、似た綴りの amide「アミド」とは窒素の結合状態や性質が異なる点に注意しましょう。
Connect amine with ammonia both in spelling and chemical structure. Picture ammonia, NH₃, and replace one or more of its hydrogen atoms with organic groups; the resulting class of compounds is amines. This structural image explains why chemists discuss primary, secondary, and tertiary amines and why an amine can react with an acid to form a salt. Keep amine separate from amide: the spellings are close, but an amide has nitrogen attached to a carbonyl group and usually behaves differently. Typical phrases such as identify an amine and amine salt reinforce its use as a countable chemistry term.
例文

This amine reacts quickly with the acid.
このアミンは酸とすばやく反応します。
Students learned how an amine can form a salt.
学生たちは、アミンがどのように塩を作るかを学びました。

amine の語源・成り立ち Etymology
ammonia（アンモニア）の語幹 am- に化学接尾辞 -ine を付けた造語。アンモニアはエジプトの神アモン（Ammon）の神殿付近で採れた塩に由来する。関連語: amino acid（アミノ酸）、ammonia。アンモニアから水素を置換した有機化合物群の総称である。
Amine was coined in nineteenth-century chemical terminology from ammonia with the chemical suffix -ine. Ammonia ultimately takes its name from sal ammoniac, “salt of Ammon,” associated historically with the region of a temple of the Egyptian god Ammon. The term amine came to designate organic derivatives formally related to ammonia, in which one or more hydrogen atoms are replaced by carbon-containing groups.
