Abstract

Abstract: In this paper, we introduce a very rapid preparation method to produce water soluble C₆₀ derivatives——fullerols by the reaction of C₆₀ with aqueous NaOH and H₂O₂ in the presence of tetrabutylammonium hydroxide(TBAH) as the catalyst, and the reaction is accelerated very much and the reaction time is shortened from 1～3 d to 1～3 h by adding H₂O₂ to replace O₂ in the air as the oxidant. FTIR, ¹H NMR and MALDI-TOF-MS proved the multi hydroxy and C₆₀ cage structure of the products. The hydroxylated fullerere epoxide——the intermediate which is very easy to hydrolyze to become fullerols was obtained, and the formation mechanism of fulleols was put forward.

Key words: C₆₀, Fullerols, Rapid preparation, Hydroxylated fullerene epoxides, Mechanism
