nematicidal activity of plant essential oils and components from coriander coriandrum sativum oriental sweetgum liquidambar orientalis and valerian valeriana wallichii essential oils against pine wood nematode bursaphelenchus xylophilus
Journal of Agricultural and Food Chemistry, 2008Co-Authors: Sangchul Shin, Ilkwon ParkAbstract:Commercial essential oils from 28 plant species were tested for their nematicidal activities against the pine wood nematode, Bursaphelenchus xylophilus. Good nematicidal activity against B. xylophilus was achieved with essential oils of coriander (Coriandrum sativum), Oriental sweetgum (Liquidambar orientalis), and valerian (Valeriana wallichii). Analysis by gas chromatography−mass spectrometry led to the identification of 26, 11, and 4 major compounds from coriander (Coriandrum sativum), Oriental sweetgum (Liquidambar orientalis), and valerian (Valeriana wallichii) oils, respectively. Compounds from each plant essential oil were tested individually for their nematicidal activities against the pine wood nematode. Among the compounds, benzaldehyde, trans-cinnamyl alcohol, cis-asarone, octanal, nonanal, decanal, trans-2-decenal, undecanal, dodecanal, Decanol, and trans-2-decen-1-ol showed strong nematicidal activity. The essential oils described herein merit further study as potential nematicides against th...

measurement and modelling of high pressure bubble and dew point data for the co2 1 Decanol 3 7 dimethyl 1 octanol system
Fluid Phase Equilibria, 2019Co-Authors: Carla Latsky, C E SchwarzAbstract:Abstract This work aims to characterise the solute-solute interaction which occurs in a ternary system containing CO2 with solutes, 1-Decanol and 3,7-dimethyl-1-octanol and to compare the ability of the RK-ASPEN and CPA models, available within the Aspen Plus® software, to predict solubility data for this system. Bubble- and dew-point data were therefore measured for three 1-Decanol + 3,7-dimethyl-1-octanol mixtures in CO2, at temperatures between 308 K and 358 K, with pressures up to 27.5 MPa and with total solute mass fractions ranging from 0.605 to 0.015. The data were measured using the static, synthetic visual phase detection method. The measured data revealed that significant solute-solute interactions exist in the ternary system. Furthermore, in mixtures where 1-Decanol dominated the mixture composition, these interactions resulted in the occurrence of a temperature inversion. The bubble- and dew-point data for the system were predicted using the RK-ASPEN and CPA models. The models were fitted using literature and experimental data. Comparison of the prediction obtained using the RK-ASPEN and CPA models indicated that the solubility data of the ternary system can better be described using the polar-based RK-ASPEN equation of state model.

high pressure phase behaviour of the co2 1 Decanol n dodecane system
Fluid Phase Equilibria, 2015Co-Authors: Sonja A M Smith, C E SchwarzAbstract:Abstract The phase behaviour of three (1-Decanol + n-dodecane)-mixtures in the presence of supercritical CO2 was investigated. Phase equilibrium measurements were conducted at temperatures ranging between 308 K and 348 K, with solute mass fractions ranging between 0.017 and 0.621. The experimental data emphasize the dominant influence of n-dodecane in the solute mixture. It has been proposed that the presence of n-dodecane interrupts the formation of alcohol multimers and thus significantly improves the solubility of 1-Decanol in supercritical CO2. The ternary system also displays a slight cosolvency effect. The experimental data was used to determine solute–solute binary interaction parameters for the RK-Aspen model in Aspen Plus®. Addition of these interaction parameters improved the correlative capability of the equation of state allowing for future improved process modelling of systems involving these components.

experimental measurement and modelling with aspen plus of the phase behaviour of supercritical co2 n dodecane 1 Decanol 3 7 dimethyl 1 octanol
Journal of Supercritical Fluids, 2013Co-Authors: M Zamudio, C E Schwarz, J H KnoetzeAbstract:Abstract Experimental phase equilibrium data for the systems CO2 + n-dodecane, CO2 + 1-Decanol and CO2 + 3,7-dimethyl-1-octanol were used to determine values for binary interaction parameters for use in the RK-ASPEN thermodynamic model in Aspen Plus®. Bubble and dew point data of the mixtures CO2 + (n-dodecane + 1-Decanol), CO2 + (n-dodecane + 3,7-dimethyl-1-octanol), CO2 + (1-Decanol + 3,7-dimethyl-1-octanol) and CO2 + (n-dodecane + 1-Decanol + 3,7-dimethyl-1-octanol) were measured experimentally in a static synthetic view cell, and compared to the data predicted by the RK-ASPEN model. The model predicted the phase equilibrium data reasonably well in the low solute concentration region; significant deviation of model predictions from experimental data occurred in the mixture critical and high solute concentration regions due to the exclusion of solute–solute interaction parameters in the model. Distribution coefficients and separation factors were determined for the multi-component mixture and separation of the alkane from the alcohol mixture with a supercritical fluid extraction process was found to be possible.

influence of the diluent on the extraction of acetic acid from the prehydrolysis liquor of kraft based dissolving pulp production process by tertiary amine
Separation and Purification Technology, 2013Co-Authors: Guihua Yang, Sarwar M Jahan, Laboni Ahsan, Yonghao NiAbstract:Abstract Different diluents including 1-Decanol, 1-octanol and 2-ethyl-1-hexanol and kerosene have been evaluated in extracting acetic acid from the treated prehydrolysis liquor (TPHL) by triisooctylamine (TIOA) or trioctylamine (TOA). Diluent played an important role in recovering acetic acid from the TPHL, thus affecting the extraction equilibrium and extraction efficiency. Polar diluent like 1-Decanol, 1-octanol and 2-ethyl-1-hexanol showed better performance than the nonpolar diluent kerosene. The maximum extraction efficiency was 68.79%, which was from 2-ethyl-1-hexanol. The organic solvent was regenerated and extracted HAc was recovered by aqueous sodium hydroxide. The regeneration efficiency can be improved by increasing molar ratio of sodium hydroxide to HAc.

recovery of acetic acid from pre hydrolysis liquor of hardwood kraft based dissolving pulp production process by reactive extraction with triisooctylamine
Bioresource Technology, 2013Co-Authors: Guihua Yang, Sarwar M Jahan, Laboni Ahsan, Linqiang ZhengAbstract:Acetic acid was one of the main compositions of the pre-hydrolysis liquor (PHL), which was recovered by reactive extraction with triisooctylamine (TIOA) diluted with Decanol. Dilution of TIOA played an important role in extracting acetic acid from the PHL. The recovery of acetic acid from the PHL by TIOA was increased from 10.34% to 66.60% with the dilution of TIOA to 20% by Decanol at the HAc to TIOA molar ratio of 1, consequently, the equilibrium distribution coefficient KD increased. The effects of time, temperature and pH on the extraction process were also studied. The extraction process was very fast. The acetic acid extraction decreased from 65.13% to 57.34% with the rise of temperature to 50°C from 20°C. A higher pH increased the dissociation of acetic acid, as a result, decreased acetic acid extraction. The hemicelluloses in the PHL were unaffected on the extraction process of acetic acid.
