In a search for natural products that could be used to control schistosomiasis, nineteen extracts of eleven medicinal plants from eastern China have been tested for molluscicidal activity against snail Oncomelania hupensis. The n-butanol fraction of the fresh leaf from Buddleja lindleyana Fortune, Buddlejaceae, showed significant activity against the snails. Statistical analysis revealed that t...

In this experimental study, the performance of diesel engine was analyzed for biodiesel derived from Calophyllum inophyllum. The impact addition additives such as N-octanol and N-butanol with inophyllum has been assessed. Impact application hybrid on emission profile used also demonstrated. Response surface analysis alcohol additives-biodiesel blend performed separately in study efficiency prof...

Esterification of lauric acid with n-butanol, catalyzed by immobilized Candida antarctica lipase (CAL) in aqueous-organic biphasic solvent system was studied. Effects of various reaction parameters on esterification were investigated, such as type and amount of solvent, amount of buffer, pH, temperature, speed of agitation, amount of enzyme, butanol and lauric acid. The most suitable reaction c...

gallium extraction from jajarm bayer process liquor (jajarm, iran) was investigated using microemulsions. also the behavior of aluminum was studied as an impurity. kelex100 (4-ethyl, 1-methyl, 7-octyl, 8-hydroxyquinoleine), iso-decanol and n-butanol, and kerosene were used as the surfactant, co-surfactant, and oil phase, respectively. ternary phase diagrams were produced using various co-surfac...

We present differential, integral, and momentum-transfer cross sections for elastic scattering of low-energy electrons by three butanol isomers, isobutanol, t-butanol, and 2-butanol. Our results were calculated with the Schwinger multichannel method in the static-exchange plus polarization approximation for collision energies from 1 to 50 eV. The present results are compared with previous calcu...

We utilize ion mobility mass spectrometry with an atmospheric pressure differential mobility analyzer coupled to a time-of-flight mass spectrometer (DMA-MS) to examine the formation of ion-vapor molecule complexes with seed ions of K+ , Rb+ , Cs+ , Br- , and I- exposed to n-butanol and n-nonane vapor under subsaturated conditions. Ion-vapor molecule complex formation is indicated by a shift in ...

AIM This study was designed to investigate the bioactive compounds in Costus afer Ker Gawl, an indigenous African medicinal plant whose leaf and stem extracts are used in the treatment of chronic inflammatory diseases, especially rheumatism and arthritis. MATERIALS AND METHODS The bioactive compounds present in the n-butanol fractions of C. afer leaf and stem were identified using qualitative...

In this work, we developed an approach of one-pot complete catalytic conversion woody biomass into two value product streams: lignin-derived aromatics (monomer yield 68.54% and oligomer 29.65% based on lignin mass) (semi-)cellulose-derived small molecular alcohols (about 59.60% mass). These could be afforded by conducting lignocellulose depolymerization over metal-alkaline catalysts in a mixed ...

A clostridial strain has been isolated that produced n-butanol, ethanol, butyrate, and acetate as major fermentation products from glucose but no acetone. At a pH of 6.6, n-butanol was formed by this microorganism only during growth. On the basis of its physiological characteristics and DNA-DNA homology data, the strain was assigned to the "Clostridium tetanomorphum" group (S. Nakamura, I. Okad...
