Use of microalgae to recycle nutrients in aqueous phase derived from hydrothermal liquefaction process

Hydrothermal liquefaction (HTL) of microalgae biomass generates an aqueous phase (AP) byproduct with limited energy value. Recycling the AP solution as a source of nutrients for microalgae cultivation provides an opportunity for a cost-effective production of HTL based biofuel and algal biomass feedstock for HTL, allowing a closed-loop biofuel production in microalgae HTL biofuel system. This paper aims to provide a comprehensive overview of characteristics of AP and its nutrients recycling for algae production. Inhibitory effects resulted from the toxic compounds in AP and alleviation strategies are discussed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C9H8O, you can also check out more blogs about4265-25-2

Effect of sodium perborate monohydrate concentrations on product distributions from the hydrothermal liquefaction of Scotch pine wood

The hydrothermal liquefaction of biomass was carried out using sodium perborate monohydrate (NaBO3¡ÁH2O) at 250, 300 and 350 C. The effects of temperature and additive concentrations on the product distributions were investigated. NaBO3¡ÁH2O was found to be very effective for the hydrothermal liquefaction of biomass at 300 and 350 C. The use of NaBO3¡ÁH2O in the liquefaction of woody biomass increased the yields of bio-oils and decreased the solid residue yields at 300 and 350 C. All concentrations of NaBO3¡ÁH 2O showed high catalytic performance at 300 and 350 C. The identified compounds in bio-oils (light bio-oils and heavy bio-oils) were mostly oxygenated hydrocarbons for both the thermal and NaBO3¡ÁH 2O runs. Furfural, 5-methyl furfural, and 5-(hydroxymethyl)furfural were only observed in the thermal run. Most of the identified compounds in the light bio-oils obtained from the thermal and NaBO3¡ÁH 2O runs were phenolic compounds. The highest heating value of the resultant heavy bio-oils was approximately 32 MJ/kg, which was obtained from the hydrothermal liquefaction of biomass at 350 C with NaBO3¡Á H2O.

Development of a simultaneous multiple solid-phase microextraction-single shot-gas chromatography/mass spectrometry method and application to aroma profile analysis of commercial coffee

A simultaneous multiple solid-phase microextraction-single shot-gas chromatography mass spectrometry (smSPME-ss-GC/MS) method has been developed for headspace analysis. Up to four fibers (50/30mum DVB/CAR/PDMS) were used simultaneously for the extraction of aroma components from the headspace of a single sample chamber in order to increase sensitivity of aroma extraction. To avoid peak broadening and to maximize resolution, a simple cryofocusing technique was adopted during sequential thermal desorption of multiple SPME fibers prior to a ‘single shot’ chromatographic run. The method was developed and validated on a model flavor mixture, containing 81 known pure components. With the conditions of 10min of incubation and 30min of extraction at 50C, single, dual, triple and quadruple SPME extractions were compared. The increase in total peak area with increase in the number of fibers showed good linearity (R2=0.9917) and the mean precision was 12.0% (RSD) for the total peak sum, with quadruple simultaneous SPME extraction. Using a real sample such as commercial coffee granules, aroma profile analysis was conducted using single, dual, triple and quadruple SPME fibers. The increase in total peak intensity again showed good linearity with increase in the number of SPME fibers used (R2=0.9992) and the precision of quadruple SPME extraction was 9.9% (RSD) for the total peak sum.

142. Thermal rearrangements of halogen substituted aryl propargyl ethers

7-Chloro-2-chloromethyl-benzofuran (13) and 3, 8-dichloro-2H-1-benzopyran (12) are the main products from the thermal rearrangement (230-260) of 2, 6-dichlorophenyl propargyl ether (7). Compounds 17, 18 and 19 are also formed, but in much smaller amounts (scheme 2 and table 1). However, in the case of the bromo-compounds 8 and 9 the rearrangement products are the benzofuran derivatives 21 and 22, containing one bromine atom less per molecule (scheme 4). The corresponding naphthyl propargyl ethers 10 and 11 can be rearranged much more easily (180) to the halogeno-naphthofurans 24 and 26 respectively. In the case of the bromo-ether 11, 2-methyl-naphtho[2,1-b] furan (25) is also formed (scheme 5). If the propargylic hydrogen atoms in 7 and 11 are replaced by deuterium atoms, then after rearrangement the deuterium atoms in the products d-13 and d-26 are found in the beta-positions to the oxygen atom of the furan ring (schemes 3 and 5). It is suggested that initially a [3s, 3s]-sigmatropic rearrangement of the aryl propargyl ethers to the 6-allenyl-6-halogeno- cyclohexa-2, 4-dien-1-ones (e.g. a) occurs and that from these the isolated products are formed via radical pathways (scheme 6). Under neutral conditions aryl propargyl ethers containing a free ortho-position give on heating benzopyran derivatives [2]. When this thermal reaction is carried out in sulfolane in the presence of powdered potassium carbonate, 2-methyl-benzofuran derivatives are formed (table 2). This leads to the possibility of preparing, depending on the conditions, either benzopyran or benzofuran derivatives by the Claisen rearrangement of aryl propargyl ethers. The mechanism for the formation of the benzofurans is given in scheme 9.

Connected nucleophilic substitution-Claisen rearrangement in flow – Analysis for kilo-lab process solutions with orthogonality

The two-step synthesis of phenol to 2-allylphenol in micro flow is investigated. This synthesis involves a nucleophilic substitution (SN2) reaction of phenol with allyl bromide towards allyl phenyl ether and the thermal Claisen rearrangement of allyl phenyl ether to 2-allylphenol. This carbon-carbon bond forming reaction route would provide a valuable path towards complex molecules. Flow cascades have turned into a powerful approach to provide chemical diversity (process-design intensification). This is enabled by chemical intensification of the Claisen rearrangement in micro flow, by reducing the reaction time to minutes without the need of a catalyst. While both individual reaction steps have been optimized separately in earlier research, an initial directly connected two-step synthesis gave low selectivity.Accordingly, the main topic investigated is how to achieve orthogonality in case of reagent mismatch between the two reactions. First, four flow process protocols using three different kinds of in-flow separation and one kinetic approach, are developed at laboratory scale. From there, process design sheets for kilolab processing set-ups of the suited approaches are developed which shed first light on their industrial practicality. In particular, it has been found that the main causes for the drop in selectivity are the presence of the base DBU and the reactant allyl bromide during the Claisen rearrangement. Three of the four investigated separation approaches demonstrated the ability to improve the overall yield – acid-base extraction, acid absorption by using ion exchange resin, using heterogeneous base, and dilution as kinetic approach. Finally, for every option, the proposed respective production set-up, anticipated advantages and drawbacks are given to facilitate a decision.

Identification of specific organic contaminants for estimating the contribution of the Elbe river to the pollution of the German Bight

GC/MS analyses have been applied to sediment samples of the German Bight in order to document the state of organic contamination as well as to identify specific molecular markers that are appropriate to estimate the discharge of anthropogenic compounds derived from the Elbe river. Detailed screening analyses revealed a wide variety of organic lipophilic compounds of biogenic, petrogenic as well as anthropogenic origin. Potential marker compounds indicating the contribution of the Elbe river could be attributed mainly to the chlorinated aromatic contaminants. Specifically, these include tetra- to hexachlorobenzenes, mono- to dichloronaphthalenes, hexachlorobutadiene, tetrabutyl tin, alkylsulfonic acid phenylesters, 1,2,3,6,7,8-hexahydro-1,1,6,6-tetramethyl-4-isopropyl-as-indacene and 4,4?dichlorodiphenylsulfide. These compounds are suitable to indicate the spatial distribution of Elbe river derived organic matter.

Lead optimization studies of cinnamic amide EP2 antagonists

Prostanoid receptor EP2 can play a proinflammatory role, exacerbating disease pathology in a variety of central nervous system and peripheral diseases. A highly selective EP2 antagonist could be useful as a drug to mitigate the inflammatory consequences of EP2 activation. We recently identified a cinnamic amide class of EP2 antagonists. The lead compound in this class (5d) displays anti-inflammatory and neuroprotective actions. However, this compound exhibited moderate selectivity to EP2 over the DP1 prostanoid receptor (?10-fold) and low aqueous solubility. We now report compounds that display up to 180-fold selectivity against DP1 and up to 9-fold higher aqueous solubility than our previous lead. The newly developed compounds also display higher selectivity against EP4 and IP receptors and a comparable plasma pharmacokinetics. Thus, these compounds are useful for proof of concept studies in a variety of models where EP2 activation is playing a deleterious role.
