Measurement and Modeling of Acridine Solubility in Supercritical Carbon Dioxide
Supercritical carbon dioxide has gained increasing attention in food and pharmaceutical processing owing to the fact that it is environmentally inexpensive, not flammable, essentially non-toxic, and it has a convenient critical point. Also, it has been attracting much attention in many fields, such as extraction of sensitive materials and pharmaceutical processing and polymerization processes. ...
متن کاملEnzymatic Transesterification Coupled to Product Extraction in Supercritical Carbon Dioxide
A mixture of fatty acids ethyl esters (FAEE), rich in short chain fatty acids, was produced and extracted in a combined reaction – extraction system, integrated by the use of supercritical carbon dioxide (scCO2). In this processing unit milk fat was partially converted to FAEE by enzymatic alcoholysis. Simultaneously, the lighter FAEE were extracted from the product mixture by flowing scCO2. Th...
متن کاملSynthesis of polyvinyl pyridine/C60 conjugates in supercritical carbon dioxide*
In the present investigation efforts have been made to synthesis polyvinyl pyridine (PvPy) /C60 conjugates through 2, 2-azobisisobutyronitrile (AIBN) initiated insitu polymerization of PvPy in scCO2.The process of synthesis was monitored under different reaction conditions ranging 1200-1800psi, 60-90 oC over 6 hours. The progress of polymerization was monitored rheoviscometrically. The concentr...
متن کاملThe influence of enzymatic pre-treatment of corn or soybean meal on their phytate content under different in vitro conditions
BACKGROUND: Phosphorous is one of the expensive nutrients in poultry feed. Therefore, improving the bioavailability of this nutrient in feed ingredients could be effective for lowering the cost of feed. OBJECTIVE: This study was performed to evaluate the effect of pre-treatment of feed ingredients by commercial enzymes and different levels of pH on releasing of phosphorus from phytate under in ...
متن کاملPectinolytic enzymes from actinomycetes for the degumming of ramie bast fibers.
Actinomycetes isolated from 10 different soil and compost samples were screened for production of pectinolytic enzyme activities when grown on pectin-containing solid and liquid media. Pectinolytic enzymes, detected by using plate diffusion tests with a medium containing ramie (Boehmeria nivea) plant material as the sole carbon source, were mainly pectate lyases, but low activities of pectinest...
