Abstract:
OxFA-processing of inedible cellulose is considered as a perspective way for the production of biogenic formic
acid (FA) which appeared to be a promising source for sustainable energy. In our work, the one-pot hydrolysisoxidation
of cellulose to FA was studied in the presence of the micellar acidic catalysts based on Mo–V–P heteropoly
acids [Cn-MIM]y/H3+x-yPMo12-xVx (n = 6, 10 and 16; x = 1, 2 and 4; y = 2–6). The influence of amount of
V, substitution of H+ by [Cn-MIM] and the length of alkyl group Cn of the cation was revealed. The optimization
of the reaction conditions was also performed. To our knowledge, heterogeneous catalysts of such a composition
were applied in cellulose hydrolysis-oxidation to FA for the first time. In the presence of C10-MIM/HPMo11V
catalyst, the optimal reaction conditions were determined: 10 g/L of cellulose, 1.25–10 g/L of catalyst, 5 MPa of
gas mixture (O2/N2 - 20/80 vol/vol) and 170–180 ◦C. Decreasing the alkyl group length of Cn-MIM+ cation or V
content into framework of heteropoly anion were revealed to rise up the yield of the target product. These
correlations were caused by the following factors. First, the decreasing acidity of micellar catalysts. Senond, the
change in distribution of electron density in heteropoly anion due to the interaction between hydrogen atoms of
alkyl group of Cn-MIM cation and oxygen atom of heteropoly anion. Third, blocking of V active sites for reagents.
Influence of acidity on catalytic properties of micellar catalysts was also revealed in the course of screening
samples with the different degree of protons substitution by C16-MIM+. The reaction rate was demonstrated to
rise with increasing degree of protons substitution by C16-MIM + cation in C16-MIM/HyPMo11V and C16-MIM/
HyPMo8V4 samples. The yield of FA up to 45 mol% can be reached over micellar HPA catalysts studied.
