Pressurized Liquid Extraction of Hemp Residue and Purification of the Extract with Liquid-Liquid Extraction
نویسندگان
چکیده
The first semi-continuous Pressurized Liquid Extraction (PLE) of hemp threshing residue with ethanol was carried out according to a 32 full factorial experimental design pressure and temperature as independent variables at 8-10-12 MPa 323-333-343 K, respectively. total- cannabidiol (CBD) yield curves were fitted the modified two-parameter Brunner equation. Best results, concerning CBD, can be achieved 12 343 K. Solvent mass-consumption operation time considerably decreased compared previous supercritical fluid extraction study on same material. Furthermore, concentration profiles evaluated mass transfer. winterized dry extracts further studied in methanol-hexane-water ternary system CBD distribution ratio, showing high methanol dependency.

298 Introduction Environmental and biological analyses are especially challenging for the analyst because sample matrices tend to be very complex and the analytes are present at very low levels. Selective and sensitive methods are needed for both sample preparation and analysis. Typically, extraction and clean-up are needed in the sample preparation, and the analyses are performed by chromatogr...

Stagewise forward mixing model considering coalescence and redispersion of drops was used to predict the performance of Rotating Disc Liquid-Liquid Extraction Contactors. Experimental data previously obtained in two RDC columns of 7.62cm diameter, 73.6cm height and 21.9cm diameter, 150cm height were used to evaluate the model predictions. Drop-side mass transfer coefficients were predicted appl...

Recovery of metabolites from fermentation broth by solvent extraction can be used to optimize fermentation processes. End-product reutilization, low product concentration, large volumes of fermentation broth and the requirements for large bioreactors, in addition to the high cost largely contributed to the decline in fermentative 2, 3-butanediol production. Extraction can ...

A new, sensitive and fast dispersive liquid-liquid microextraction (DLLME) coupled with micro-solid phase extraction (μ-SPE) was developed for determination of zearalenone (ZEN) in wheat samples. The DLLME was performed using acetonitrile/water (80:20 v/v) as the disperser solvent and 1-octanol as the extracting solvent. The acetonitrile/water (80:20 v/v) solvent was also used to extract ZEN f...
