Synthesis of jet fuel range high-density dicycloalkanes with methyl benzaldehyde and acetone

Abstract

In this work, jet fuel range high-density dicycloalkanes were manufactured from methyl benzaldehyde and acetone, two platform compounds which may be obtained from lignocellulose. Protonated titanate nanotube (PTNT), a cheap...

One-dimensional titanate nanotube materials: heterogeneous solid catalysts for sustainable synthesis of biofuel precursors/value-added chemicals—a review

“…Recent advances in nanoscience and nanotechnology have paved the way for more operational, “green,” and long-lasting nanostructured catalytic systems. Due to their unique physicochemical properties, for instance, a high surface-to-volume ratio, strong dispersibility, and increased accessibility of surface hydroxyl groups, Lewis acid sites (LAS) and Bronsted acid sites (BAS), 1D HTNT has been established as attractive catalysts and supports [ 8 , 11 – 13 ]. Given that nanomaterials are a type of material whose dimensions are described by the nanometer scale (typically ranging from 1 to 100 nm) in the field of nanoscience and nanotechnology [ 28 – 31 ], the term “nanostructure” is commonly used to designate the geometrical structure of nanomaterials.…”

“…Herein, we report a series of published works of a new kind of efficient sodium/protonated titanate nanotubes hydrothermally obtained via nanotechnology applications. The current method holds a lot of promise for the future development of new families of cost-effective and reliable solid catalysts on eco-friendly precursors, scalable and sustainable protocols [ 1 , 8 , 9 , 12 , 13 ]. The benefits of solid acid catalysts as heterogeneous over homogeneous in chemical industrial transformation processes have been previously reported Hideshi Hattori et al[ 41 ]…”

“…In another study conducted on the synthesis of biofuel precursor’s biomass-based platform, molecules were used. Methyl benzaldehyde (2-and-4 methyl benzaldehyde) and acetone obtainable from lignocellulose were transformed to biofuels precursors over solid acid protonated titanate nanotube (PTNT) through aldol condensation [ 8 ]. The authors first manufactured series of protonated titanate nanotubes from commercial P25 TiO 2 and aqueous sodium hydroxide via a hydrothermal method, as earlier reported by Kasuga et al .…”

“…Technically and economically, with the abundance of biomass on earth, world energy consumptions can adequately be addressed [ 1 , 6 , 7 ]. Thermal, biochemical, and chemical routes are three major pathways to actualize the conversions of renewable feedstocks to fuel intermediates, fuels, and value-added chemicals (VACs) [ 8 , 9 ]. However, the catalytic conversion pathway is the most effective route for synthesizing biofuels like bioethanol and biogas and value-added chemicals (VACs).…”

“…According to Alwin Mittasch’s statement, “Chemistry without catalysis would be a sword without a handle, a light without brilliance, a bell without sound” [ 10 ]. According to the above statement, the active role of sustainable catalytic systems cannot be restrained to successfully attain the quality and value of the final product in biomass transformation [ 1 , 8 , 9 ].…”
