Phosphorylated ordered mesoporous carbon as a novel solid acid catalyst for the esterification of oleic acid

• Phosphorylated ordered mesoporous carbon solid acid catalyst was obtained.
• POMCs have high amounts of acid and well-ordered mesoporous structures.
• The COP and CPO3 species existed on the surface of POMC.
• POMCs have good catalytic activity for the esterification of oleic acids.
• POMC showed good reusability.

A novel phosphorylated ordered mesoporous carbon (POMC) solid acid catalyst has been prepared by modifying mesoporous carbon with phosphoric acid, and was employed to catalyze the esterification oleic acid with methanol. The effects of the carbonization temperature on the type of phosphorus species formed, the phosphorus content and the amount of acid in the POMC were investigated. A mechanism for the phosphorylation of the ordered mesoporous carbon is proposed. The POMCs have good catalytic activity for the esterification of oleic acid and showed good reusability.
