Abstract:
PP-171 Новый механизм каталитического окисления лигнина в ванилин
The new mechanism of oxidative destruction of lignins is proposed. It begins from the well-known step of removing electron from the phenolate oxygen atom followed by the steps of oxidation of the side-chain y-carbon atom producing quinone methide and then the substituted coniferyl aldehyde. The latter cleaves into vanillin by the known mechanism of retroaldol destruction. Experimental facts supported the mechanism are obtained and discussed.
