Abstract

Heteropoly acids H3PW12O40 and H4SiW12O40 have been found to be efficient catalysts for condensation of isophytol with 2, 3, 5-trimethylhydroquinone and 1-acetoxy-4-hydroxy-2-methyl-naphthalene in the syntheses of vitamins E and K1, respectively.

Abstract

Установлено, что гетерополикислоты H3PW12O40 и H4SiW12O40 являются эффективными катализаторами конденсации изофитола с 2,3,5-триметилгидрохиноном и 1-ацетокси-4-гидрокси-2-метилнафталином в синтезе витаминов E и K1, соответственно.
