Plants re-emit a substantial fraction of their assimilated carbon into the atmosphere as biogenic volatile organic compound. According to the presence of relatively high amount of methanol in herbal distillates, finding different concentrations of ethanol in such drinks is expectable, as several studies appeared that produced ethanol by plants emits into the atmosphere as do methanol. In this s...

Narrow temperature range distillates from biologically active solvent refined coal-l and -II heavy-end coal liquids were fraction ated according to chemical class and assayed for initiation of skin carcinogenesis in CD-1 mice. In addition, instrumental chem ical analyses were performed on the distillates and their chemical fractions. Results showed that initiation activity in these complex fuel...

Ultraviolet resonance Raman spectroscopy has been used to characterize the polycyclic aromatic hydrocarbon composition of a series of distillates of coal-derived liquids. The UV Raman spectra easily monitor changes in the polycyclic aromatic hydrocarbon composition as a function of distillation temperature. Specific species, such as pyrene, can be determined by judicious choice of excitation wa...

Abstract The casks that have contained for a certain time Sherry wines are known as Casks ® and their use value increased in recent years, they confer unique organoleptic properties to the distillates beverages aged inside them. During seasoning, these yield compounds from wood into wines, at same time, retain some which, turn, transferred casks, so acts transfer vector between two alcoholic be...

The accurate determination of the preexisting ammonia or of the amide nitrogt.n of tobacco is rendered difficult by the volatility of nicotine which distils over more or less completely when the standard procedures for the estimation of these forms of nitrogen are employed. A number of attempts has been made to devise methods whereby corrections for the nicotine content of such distillates may ...

The aim of this study was to evaluate the antimicrobial activity wood distillates obtained from Scots pine (Pinus sylvestris) sawdust in order explore new alternatives for utilization industry by-products. were produced by slow pyrolysis thermal conversion three process phases with increasing temperatures, namely drying, torrefaction and pyrolysis, cooling units different temperatures condensat...
