ここで、Mは、水素イオン、又は、周期表第2族及び第4〜14族の元素からなる群から選ばれる金属または半金属のカチオンであり、Yはハロゲン化物イオン、硫酸イオン、硝酸イオン、炭酸イオン、炭酸水素イオン、硫化物イオン、酸化物イオン、水酸化物イオン、アルコキシドイオン、リン酸イオン、酢酸イオン、及び過塩素酸イオンからなる群から選ばれるアニオンであり、n及びmは、カチオンMの価数×n=アニオンYの価数×mを満たす数である。
その他に、ルイス酸触媒として固体酸を用いてもよい。固体酸としては、活性白土、酸性白土、ゼオライト、ヘテロポリ酸、イオン交換樹脂などが挙げられる。
活性白土は、天然に産出する酸性白土(モンモリロナイト系粘土)を硫酸などの鉱酸で処理したものであり、多孔質構造をもった化合物である。共に一般的な化学成分として、SiO2、Al2O3、Fe2O3、CaO、MgOなどを有する。
ヘテロポリ酸とは、一般的には異なる2種以上の酸化物複合体からなる複合酸化物酸、およびこれらのプロトンの一部もしくはすべてを他のカチオンで置き換えたものである。ヘテロポリ酸は、例えば、リン、ヒ素、スズ、ケイ素、チタン、ジルコニウムなどの元素の酸素酸イオン(例えば、リン酸、ケイ酸)とモリブデン、タングステン、バナジウム、ニオブ、タンタルなどの元素の酸素酸イオン(バナジン酸、モリブデン酸、タングステン酸)とで構成されており、その組み合わせにより種々のヘテロポリ酸が可能である。
ヘテロポリ酸を構成する酸素酸の元素は特に限定されるものではないが、例えば、銅、ベリリウム、ホウ素、アルミニウム、炭素、ケイ素、ゲルマニウム、スズ、チタン、ジルコニウム、セリウム、トリウム、窒素、リン、ヒ素、アンチモン、バナジウム、ニオブ、タンタル、クロム、モリブデン、タングステン、ウラン、セレン、テルル、マンガン、ヨウ素、鉄、コバルト、ニッケル、ロジウム、オスミウム、イリジウム、白金などが挙げられる。
