Understanding the enhanced production of poly-aromatic hydrocarbons during the pyrolysis of lignocellulosic biomass components under pressurized entrained-flow conditions

The entrained-flow pressurized pyrolysis of lignin, cellulose, and xylan was investigated to determine the composition of pyrolysis products and the reaction mechanisms. The influence of biomass components (lignin, cellulose, and xylan) and pyrolysis conditions was investigated. The results showed that under atmospheric pressure, the decomposition of lignin formed saturated aliphatic hydrocarbons (SAHCs), phenolics, and PAHs, while cellulose and xylan mainly generated phenolics, sugars, carbonyls, alcohols, and PAHs. Increasing the pyrolysis pressure and temperature was found to drastically promote the generation of PAHs, accompanied by a decrease in phenolics, SAHCs, sugars, carbonyls, and SRAHCs. The ring growth via Diels-Alder cycloaddition reaction pathways in combination with hydrogen abstraction/C2H2 addition (HACA) was postulated to be the mechanism of the formation of PAHs. The 4-ring PAHs (pyrene, fluoranthene) and 3-ring PAHs (phenanthrene, fluorene) were found to dominate the lignin bio-oil, while the bio-oil from cellulose and xylan mainly contained 2-ring PAHs (naphthalene). Elevated pressures and temperatures were also found to significantly increase the selectivity of H-2 in the bio-gas.

General Procedure for Carbamate FormationThe desired alcohol (1.0 equiv.) was dissolved in DCM (0.3 M) in a flame-dried round- bottom flask under a nitrogen atmosphere at 00C. Pyridine (1.0 equiv.) was added followed by 2,2,2- trifluoroethylisocyanate solution (1.0 equiv., stored at -200C) added dropwise. The resulting solution was warmed to ambient temperature and stirred for two hours or until TLC showed complete consumption of the alcohol. The crude reaction was concentrated in vacuo. Flash chromatography (silica gel, DCM) provided the corresponding carbamate .; Compound 1 : Yield: 0.533 g, 97%Physical State: white solid mp: 42-43 0C Rf: 0.65 (silica gel, DCM)IR (film) Vmax: 3462, 3016, 2970, 2359, 1739, 1522, 1366, 1229, 1156 cm”11H mm (500 MHz, CDCl3) : delta 5.11-5.09 (m, 1 H) , 4.96- 4.93 (m, 1 H) , 3.79-3.74 (m, 2 H) , 1.62-1.58 (m, 2 H) , 1.48-1.46 (m, 2 H) , 1.29-1.25 (m, 2 H) , 0.90-0.88 (m, 12 H)13C NMR (125 MHz, CDCl3) : delta 156.4, 127.7-121.0 (q, J = 277 Hz) , 73.3, 44.3, 43.1-42.3 (q, J = 34 Hz) , 24.8, 23.2, 22.4HRMS (ESI) : calcd. for Ci2H22F3NO2Na [M + Na+] 292.1495, found 292.1498

108-82-7, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 108-82-7, name is 2,6-Dimethylheptan-4-ol. This compound has unique chemical properties. The synthetic route is as follows.

General procedure: NaOCl¡¤5H2O crystals (2.0 g, 12.2 mmol) were added in oneportion to a mixture of Bu4NHSO4 (0.17 g, 0.50 mmol),TEMPO (21 mg, 0.13 mmol), and 1 (1.30 g, 10.0 mmol) inCH2Cl2 (10 mL) at 5 C. After 15 min, GC monitoringshowed that 1 had been consumed. The reaction was stoppedafter 0.5 h by quenching with aq sat. Na2SO3 solution (20mL). The organic layer was separated, and the aqueous layerwas extracted with CH2Cl2 (30 mL). The combined organiclayers were washed with H2O (30 mL), dried over Na2SO4,and concentrated to give 2 as colorless oil (1.27 g, crudeyield of 99.2%, GC analysis showed the product to be 96.8%pure). A 0.42 g portion of the crude 2 was purified by bulbto-bulb distillation (6 kPa, 120-130 C) to afford pure 2(0.40 g, 95%). GC-MS analysis gave identical results tothose of an authentic sample.

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 108-82-7, 2,6-Dimethylheptan-4-ol.
