However, the number of long-chain hydrocarbons in the aldehydes may be limited due to substrate solubility if the reaction is carried out solely in an aqueous environment because the long-chain hydrocarbon would protrude out of the hydrophobic cleft toward the water milieu in the direction similar...
Aromatic hydrocarbons are one of the most abundant classes of organic compounds in nature. They are primarily produced by plants as soluble secondary metabolic products or as components of the structural polymer lignin1. Moreover, considerable amounts of toxic aromatic hydrocarbons, in particular, of...
Because of its different sources, which are characterized by heterogeneous composition, various contaminants are present in composts, including heavy metals, antimicrobials, phenols, phthalates, pesticides, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, perfluorinated compounds, personal care products...
The alkali metals, such as Li and Na, can react with some aromatic hydrocarbons in ether solvents to form a dark green alkali solution at room temperature. Such solutions have been known as radical anions and widely used as reducing agents in chemical synthesis since the 1930s20,21,22,23,24...
aliphatic hydrocarbons, both saturated and unsaturated, such as methane, ethane, propane, butane, pentane, hexane, ethylene, acetylene and propylene; oxygenated hydrocarbons such as acetone, and methanol; aromatic hydrocarbons such as benzene, toluene, and naphthalene; and mixtures of the above, for ...
(b). Laser Raman spectra of liquid-phase and gas-phase hydrocarbons in type 3 fluid inclusions. The peaks at 2800 to 3000 cm−1 and approximately 3066 cm−1 and 1610 cm−1 are the characteristic peaks of alkanes and polycyclic aromatic hydrocarbons (PAHs), respectively, and the peaks ...
Unfortunately, the NHPI derivatives proposed in the literature for industrial use have been synthetized to be dissolved in liquid hydrocarbons, eventually using a co-solvent to increase their solubility [24,25]. Therefore, they are not suitable to be tested for the envisaged biological application. ...
This article is devoted to a study of the question of existence (in time) of weak solutions and the derivation of qualitative properties of such solutions for the nonlinear viscoelastic wave equation with variable exponents and minor damping terms. By using the energy method combined with the Faed...
Carbon in the elemental composition comes from both organic hydrocarbons related to XSBR and inorganic carbonate in calcium carbonate. For unmodified composites (top), an aggressive pozzolanic activity of FCSs is visible. The hard and water-impermeable aluminosilicate shell of FCSs suffered from ...
Benzene was the main product for all the under-study catalysts, along with cyclohexene, cyclohexane, cyclohexanone, and C5-C6 hydrocarbons. Figure 9. Reaction pathway for HDO of phenol over various supported TMP catalysts. Adapted from Ref. [118]. Inocencio attempted to correlate the measured ...
