Abstract:

Bagasse alkali lignin is the primary constituent of pulping black liquor. The phenolic products such as phenol, 2,6-dimethoxy-phenol and 2-methoxy-phenol were obtained by catalytic liquefaction from bagasse alkali lignin, with the aim of enhancing its use value. In the investigation, under optimal conditions, using SiO2-Al2O3 or FeS as catalyst, the phenols yield reached 54.10% and 55.18%, respectively. HPLC spectrum showed that the phenolic products of them were different. FT-IR and H-NMR spectrums showed that, using SiO2-Al2O3 as the catalyst, the α-O-4 and β-O-4 ether bonds and C-Cα bonds o

The mode for ligand coordination has been determined by IR and EPR spectra. The carboxyl and amino group of dyes coordinates to the Cu(II) atom as a unidentate or as a chelating ligand.

Abstract:

Methoxy-(2-trimethylsilyl)ethoxycarbene reacts with two equivalents of dimethyl acetylene dicarboxylate, methyl propiolate, phenyl acetylene, or phenyl isocyanate without rearrangement of the carbene group. N-Phenylmaleimide captures the carbene with 1:1 -stoichiometry. The structure of the product implies that a migration of the trimethylsilylethyl group from oxygen to carbon accompanies that reaction. A mechanism for that complex rearrangement is proposed. Phenol and tert-butyl alcohol afford the orthoformates expected from overall insertion of the carbene into the OH bond. Key words: dialko

In this study, the Box-Behnken Design (BBD) was employed to investigate the effects of wood particle size, pyrolysis temperature, and pyrolysis time on the production of wood vinegar from Indonesia “bengkirai” wood (Shorea laevis Ridl). Characterization of wood vinegar was conducted by gas chromatography-mass spectrometry (GC-MS). Three variable designs consisting of wood particle size (2.00, 2.38, and 3.36 mm), pyrolysis temperature (350, 400, and 450 °C), and pyrolysis time (105, 120, and 135 min) were employed in a BBD response surface methodology (RSM-BBD).

This study aims to investigate the production and characterization of the chemical composition of various quality classifications of liquid smoke that is derived from lontar Shells. Liquid smoke is generated from dried lontar shell raw material that takes on pyrolysis at approximately 400 ℃. A vertical column-model pyrolyzer equipped with a 6-meter-long spiral-shaped condenser supports the productivity of the pyrolysis process. After being collected, the liquid smoke is allowed to settle for a duration of seven days. The process involves distillation at 130℃, followed by purification through a

Abstract:

Generally, wood vinegar (WV) is produced from one-step carbonization for all purposes, i.e., antibacterial, food preservative, and agriculture. This carbonization process will result in WV with high phenol content. High phenol is beneficial for antimicrobials but can cause damage to plants if the WV concentration is not suitable. This research aimed to examine the effects of pyrolysis temperature stratification on three other biomass pyrolysis. This study uses hardwood, softwood, and nonwood waste, which are pyrolyzed with temperature stratification, namely 200, 300, 400, and 500 oC. Proximate

Abstract:

Three novel Ni complexes with the Schiff base ligand 2-methoxy-6-(E-2-pyridyliminomethyl)-phenol (L1) are described. In comparison with the similar 2-(pyridine-2-ylimino-methyl)phenol (pymp), the mode of coordination of L1 is altered due to the presence of methoxy substituent introducing the sterical hindrance. During the synthesis of the complexes, partial hydrolysis of the ligand was observed. Since such immediate hydrolysis of L1 was not detected during the reactions of Zn(II) and Cu(II) salts with L1, the DFT calculated structures of a series of similar Zn, Cu, Ni, and Co complexes with L1

These derivatives are synthesized from the 5-{(E)-[4-(chloromethyl)phenyl]diazenyl}-2-hydroxybenzaldehyde and 4-substituted aniline, such as 4-methyl aniline, 4-chloro aniline,and4-methoxy aniline.
