Catalytic production and application of bio-renewable butyl butyrate as jet fuel blend- A review

Microbial cell factory for butyl butyrate production: Knowledges and perspectives

“…This method has been abandoned due to the awful reaction condition (requires high temperature–200°C and concentrated sulfuric acid), environmental pollution and equipment corrosion (Zhang et al., 2017 ). To overcome such issues in butyl butyrate production, mild reactions, such as Tishchenko reaction and Acetylation are employed at room temperature (Kushwaha et al., 2022 ). Nevertheless, these reactions still rely on the petroleum refining industry.…”

Exploring a Streptomyces wax synthase using acyl-SNACs as donor substrates

“…4 Moreover, short chain esters, such as hexyl or ethyl acetate, can be utilised as both food additives and fragrances, while they can also function as drop-in fuels or lubricants. 5–7 Long-chain wax esters are not only exploited as cosmetics or biodiesels, but also as commercial vegetable oils and fats. 8,9 Additionally, both butyl and hexyl benzoate were reported as key esters responsible for the sweet aroma of different fruit species.…”

Upgrading bio-butanol in the presence of copper-hydrotalcite derived mixed oxides: From batch to continuous flow catalytic process highly selective to butyl butyrate

“…BB is a promising candidate for blending with jet fuel [8,9] and with gasoline, being completely miscible with it, thus allowing good engine performances and low pollutants emissions [10]. On the other hand, 2EH is an important intermediate for the production of plasticizers, adhesives and paints and it is also used as petroleum additive to reduce its freezing point [11].…”

“…This single-step approach appears particularly interesting and sustainable when cost-effective heterogeneous catalytic systems not involving noble metals are employed. Differently from the DHC of ethanol to ethyl acetate, DHC of BuOH to BB in the presence of heterogeneous catalysts has been scarcely studied to date (Table 1) [13].…”
