Jonesova oksidacija

Jonesova oksidacija, je hemijska reakcija opisana kao oksidacija hromnom kiselinom primarnih i sekundarnih alkohola u karboksilne kiseline i ketone, respektivno.^[1]^[2]^[3]^[4]^[5]^[6]^[7] Jonesov reagens - rastvor hrom trioksida u koncentrovanoj sumpornoj kiselini – se koristi kao oksidaciono sredstvo.

Jonesov reagens takođe kompletno oksiduje aldehide u karboksilne kiseline.

Rastvarač aceton ima primetnog uticaja na osobine hromne kiseline. Oksidacija je veoma brza, egzotermna, i prinosi su tipično visoki. Ovaj reagens retko oksiduje nezasićene veze.

Hromijum ostatak je veoma toksičan, i mora se obratiti pažnja da je uklonjen na korektan način.
