複素環(huán)式化合物

複素環(huán)式化合物は分子中で環(huán)狀構(gòu)造を有する有機化合物の一種であり，環(huán)を構(gòu)成する炭素原子に加えて，一つ又は複數(shù)の窒素原子、硫黃原子、酸素原子等の他の原子を含有する。一つの環(huán)のみを含有すれば，単環(huán)式化合物と呼ばされ，例えばフラン、チアゾール、ピリジン；二つ又は二つ以上の環(huán)を含有すれば，多環(huán)式化合物と呼ばされ，例えばキノリン、プリン等。その中で性質(zhì)が最も穏やかでかつ最も一般的なのは5員又は6員複素環(huán)である。簡単な複素環(huán)はベンゼン又は他の複素環(huán)と結(jié)合して二環(huán)、三環(huán)又はより複雑な環(huán)系を形成することができる。ある複素環(huán)は芳香族化合物の特性を有し，例えば置換反応を起こしやすく，付加反応を起こしにくく，酸化剤と合わせて使用する時にその化學(xué)的性質(zhì)が穏やかである。複素環(huán)式化合物は自然界に広く存在し，例えば核酸、ほとんどのビタミン、クロロフィル、ヘモグロビン、ほとんどのアルカロイド、色素等。一部の複素環(huán)式化合物は芳香族性を有し，例えば植物中のクマロン、シスジャスモン，動物中のシベトン等?；瘜W(xué)合成農(nóng)薬中でこの種類の化合物は多く，例えば除草剤のアトラジン、アミトロール、イソメチオジン，殺蟲剤のプロパルギット、キナルホス，殺菌剤のトリクロロイソシアヌル酸、チオキノックス等。簡単な複素環(huán)式化合物は有機化學(xué)工業(yè)の重要な原料である。環(huán)系を構(gòu)成する炭素原子に加えてO，S，N等のヘテロ原子を含有する環(huán)狀化合物は複素環(huán)式化合物と総稱される。この定義に従って，厳密には環(huán)形無水コハク酸、環(huán)形イミド、ラクトン、ラクチド、環(huán)形無水物、ラクタム、環(huán)狀エーテル等も複素環(huán)式化合物に屬し，しかしこれらの化合物は性質(zhì)が脂肪族と類似し，かつ鎖式化合物を縮合して取得しやすいとともに，開環(huán)から鎖狀化合物に変換しやすいため，一般的に脂肪族とともに検討する。そのため複素環(huán)式化合物は特に環(huán)系が穏やかでかつ異なる芳香族性を有する複素環(huán)式化合物を指し，即ち芳香族複素環(huán)化合物である。有機複素環(huán)式化合物は開鎖、炭素環(huán)、複素環(huán)という三種類の有機化合物の一種であり，その種類が膨大で，その數(shù)量が多く，すべての既知の有機化合物の約1/3を占め，かつ生物界に広く存在し，生物の成長、発育、生殖、及び遺伝、変異等と密接な関係がある。通常の複素環(huán)式化合物はフラン、チオフェン、ピロール、キノリン、カルバゾール等を含む。これらの複素環(huán)式化合物は有機合成又は醫(yī)薬、農(nóng)薬、溶剤等に広く用いられる。無色でかつ特別な臭いを有する液體又は結(jié)晶であり，その比重が水より小さく又はそれに近く，毒性があり，いくつかの有機溶剤に溶解でき，水にわずかに溶解する?；鸱N、高熱、酸化剤及び強酸と接觸すると燃焼又は爆発を引き起こすことができ，それに毒性のある硫黃酸化物や窒素酸化物のガス狀物質(zhì)を析出する。フランは空気で過酸化物を形成し，蒸留すると爆発を引き起こすことができる。危険物の管理過程において，火災(zāi)、爆発、毒性の危険性の大きさによって，それぞれ可燃性液體、可燃性固體、有機有毒物質(zhì)に分類される；貯蔵と使用時に，その前の二種はA火災(zāi)、B火災(zāi)を引き起こす危険物として，後者はC火災(zāi)を引き起こす危険物として火災(zāi)管理を行う。発火時に，泡消火剤、粉末消火剤、水ミスト、1211、炭酸ガス消火剤等の消火剤を利用して消火を行うことができる。
