Ethanol production by extractive fermentation
Biotechnology and Bioengineering, 1982AbstractThe ideal method to produce a terminal metabolite inhibitor of cell growth and production is to remove and recover it from the fermenting broth as it formed. Extractive fermentation is achieved in the case of ethanol production by coupling both fermentation and liquid‐liquid extraction, The solvent of extraction is 1‐dodecanol (or a mixture 1 ...

Effects of the ethanol extract of Cichorium intybus on the immunotoxicity by ethanol in mice
International Immunopharmacology, 2002Effects of the ethanol extract of Cichorium intybus (CIEE) on the immunotoxicity of ethanol (EtOH) were investigated in ICR mice. Mice were divided into four groups, and CIEE at dose of 300 mg/kg was orally administered to mice daily for 28 consecutive days, and normal mice were given vehicle.

Nutritional Evaluation of Ethanol-Extracted Lentil Flours
Journal of Agricultural and Food Chemistry, 2001Lentil flours were extracted with 80% ethanol at 25 and 50 degrees C for 1, 2, or 3 h. The various nitrogen fractions, soluble carbohydrates, three amino acids (Lys, His, and Tyr), available lysine, protein digestibility, and vitamins B(1) and B(2) were analyzed to evaluate the effect of extraction.

Ethanol extraction of soybean oil
Journal of the American Oil Chemists' Society, 1962AbstractExtraction of soybean flakes with 90, 95, 98 and 100% ethanol resulted in more rapid lipid and less rapid non‐lipid removal with the increasing ethanol concentrations. There was little difference in the quality of the oil produced by the different solvents. Protein content of the residual meal averaged 52.1%.

Journal of Heat Recovery Systems, 1986
A process for the separation of ethanol from water using solvent extraction at elevated pressures is disclosed. Separation is effected by contacting aqueous ethanol with either propylene (propene), allene (propadiene), methyl acetylene (propyne), or methyl allene (1,2-butadiene).

Acidic ethanol extraction of cottonseed
Journal of the American Oil Chemists' Society, 1992Ethanol (EtOH) is being evaluated as an alternate solvent to hexane for the extraction of glanded cottonseed. Hot EtOH, needed for efficient oil and aflatoxin extraction, binds gossypol to protein. However, this binding can be minimized by acidifying aqueous EtOH with a tribasic acid, such as phosphoric or citric.

Ethanol dehydration by extractive distillation
Journal of Chemical Technology & Biotechnology, 1992AbstractExperiments and process simulation enable favourable operating conditions to be determined for the extractive distillation of ethanol—water, with ethylene glycol as a solvent. The solvent molar rate to feed molar rate ratio S/F = 0·6 and the reflux ratio R = 0·5 were determined in order to achieve at least 99·5 mole % purity of ethanol.

Reaktive-Membran-Extraction of Ethanol
Chemical Engineering & Technology, 1999In this work a model system consisting of membrane extraction and consecutive enzymatic conversion is tested for the possible technical recovery of ethanol. This method could be especially useful if not ethanol but the ester is the desired product. Ethanol should be extracted from the aqueous phase in a hollow fiber module and converted in the octane ...

Uniform design-comprehensive scoring method was used to investigate the effects of ethanol dosage, ethanol concentration and extraction time, based on the evaluation index from transfer rates of epimedin A, epimedin B, epimedin C, icariin and baohuoside Ⅰ, which are the main active components in Epimedii Folium.
