“…Os acetais formados na reação com butiraldeído podem ser utilizados como aditivos ao diesel, diminuindo em cerca de 20% a emissão de particulados. 21 A polaridade e aplicabilidade dos acetais e cetais do glicerol podem ser modificadas pela funcionalização da hidroxila remanescente. Reações com agentes alquilantes ou acilantes levam à formação de compostos multifuncionalizados com aplicações diversas.…”

“…They induce reduction in particulate emissions and/or improvement in cetane index of the fuel [8][9][10]. Among the chemical structures having this potential [11], we will quote mainly ethers, acetals and carbonates. Starting from glycerol, which is intrinsically insoluble in Diesel fuel, we propose to develop chemical modifications intended to make it soluble and to introduce oxygenated functions potentially interesting for the required properties.…”

“…This cyclic acetal has shown interesting results when applied as a green fuel additive [32][33][34] and, at the same time, represents a sustainable alternative for the valorisation of the excess glycerol, obtained as a byproduct of the increasing biodiesel production [35]. The acetalization of glycerol with acetaldehyde is the most common pathway for the synthesis of GEA, obtained as an isomeric mixture containing cis-5-hydroxy-2-methyl-1,3-dioxane, trans-5-hydroxy-2-methyl-1,3-dioxane, cis-4-hydroxymethyl-2-methyl-1, Nomenclature C 0;i molar concentration of compound i in the bulk phase at the beginning of a breakthrough experiment mol L À1 C b;i molar concentration of compound i in the bulk phase mol L À1 C in;i molar concentration of compound i fed to the fixed bed reactor during a breakthrough experiment mol L À1 C p;i molar concentration of compound i in the intraparticle fluid mol L À1 C p;i average molar concentration of compound i in the intraparticle fluid mol L À1 C out;i molar concentration of compound i at the fixed bed reactor outlet during a breakthrough experiment mol L À1 D ax axial dispersion coefficient cm 2 min [36][37][38].…”
