A new bio-based norbornene polymer was prepared starting from β-angelica lactone, prepared in a sustainable and scalable manner from the platform chemical levulinic acid. The new material displays transparency comparable to petrochemical-derived polynorbornene.

Levulinic acid has been identified as a promising green, biomass derived platform chemical. Since the availability of fossil resources diminishes, the conversion of carbohydrates to Levulinic acid has become increasingly important. ZSM-5 supported SO42-/ZrO2 solid acid catalyst have been applied for the dehydration of glucose to Levulinic acid. With ZSM-5 supported SO42-/ZrO2 solid acid as the catalyst, an optimized Levulinic acid yield was obtained at 180 °C for 2.5 h with 3 g ZSM-5 supported SO42-/ZrO2 catalyst solid acid catalys and the highest Levulinic acid yield was 55.035%.

В данном исследовании была разработана методика синтеза катализаторов на основе цеолитов типа ZSM-5 с различным соотношением Si/Al и количеством кислотных центров, модифицированных оксидом вольфрама (VI). Синтезированные катализаторы были охарактеризованы и протестированы в реакции превращения моносахаридов (фруктозы и глюкозы) в 5-гидроксиметилфурфурол и левулиновую кислоту. Было показано, что введение в состав цеолитов ZSM-5 частиц оксида вольфрама приводит к заметному увеличению количества активных кислотных центров на поверхности катализатора, играющих важную роль в реакции дегидратации моносахаридов. В результате модификации заметно возросла каталитическая активность цеолитов. Результаты исследования показывают перспективность использования цеолитов типа ZSM-5, модифицированных оксидом вольфрама (VI), для конверсии биомассы в платформенные химические соединения. In this study, a method was developed for the synthesis of catalysts based on zeolites of the ZSM-5 type with different Si/Al ratios and the number of acid sites modified with tungsten (VI) oxide. The synthesized catalysts were characterized and tested in the reaction of converting monosaccharides (fructose and glucose) into 5-hydroxymethylfurfural and levulinic acid. It was shown that the introduction of tungsten oxide particles into the composition of ZSM-5 zeolites leads to a noticeable increase in the number of active acid sites on the catalyst surface, which play an important role in the dehydration reaction of monosaccharides. As a result of the modification, the catalytic activity of zeolites has noticeably increased. The results of the study show that the use of zeolites of the ZSM-5 type, modified with tungsten (VI) oxide, is promising for the conversion of biomass into platform chemical compounds.
