The infrared spectroscopy results indicate identical chemical functional groups between the bio-oil and the petroleum asphalt binder though acid, ether, ester and alcohol compounds were also observed within the bio-oil.
For example, as seen in Reactions 9 11, the cleavage of -OH was an important source for H2O formation, while other groups such as ether, ester, and anhydride that underwent pyrolysis at high temperature would produce oxygen free radicals to generate H2O eventually as well.
In this work, COSMO-SAC model was employed to screen the most promising extractant from 40 organic solvents, including alkanes, arenes, ethers, esters and ketones.
Moreover, the continuous formation of ethers, esters and LixPOyFz compounds on the surface of the electrodes is found for all coating materials.
In this work, the ASOG model for the activity coefficient is used to predict LLE data for 15 binary and 09 ternary systems at 101.3 kPa and several temperatures; all the systems are formed by ionic liquids including the tetrafluoroborate anion plus alkanes, alkanols, water, ethers, esters and aromatics.
In cluster 8, there are 15 VOCs belonging to this cluster, which consist of epoxide, ethers, esters, and alcohols.
Various chemicals contained in the ladderane lipids, such as fatty acids, glycerol diethers, glycerol ether-esters, and sn-2 glycerol monoether, would be analyzed through these procedures (Sinninghe Damste et al. 2002, 2005).
Esters, ketones and ether esters are suitable solvents for clear and pigmented PU coating systems.
A variety of substituents, such as hydroxyl, ether, ester, carboxyl, and alkyl groups are attached to the discrete/condensed aromatic rings in coal to form the main structure of coal macromolecules (Poutsma 1990; Ndaji et al. 1997).
iii) Although alkyl, ether, ester, alkene and C−F functional groups were tolerated in various degrees, some aryl bromide-containing substrates (e.g. 8-bromo-3-nitro-2 H-chromene) and benzylic (E -BnCH−CHNO2 wE -BnCH−CHNO2ated and led only to decomposition.
(110) The most commonly used hydroxyl protecting groups are ethers (benzyl ethers), esters (acetates, benzoates), and acetals (benzylidene and isopropylidine acetals).
