The article presents the results of electromagnetic activation petroleum feed in vortex layer apparatus. It is shown that under influence, there a significant increase proportion straight-run gasoline fraction distillate, as well change physicochemical parameters light fractions obtained result cavitation effect and low-temperature cracking. has been established processes wave action on oil occ...

The use of oak barrel alternatives, including chips, staves and powder, is quite common in the production spirits obtained from distillation vegetal fermented products such as grape pomace. This work explored unconventional wood formats peeled sliced wood. poplar was also evaluated to verify its technological uses produce aged spirits. To this aim, GC-MS analyses were carried out obtain an arom...

The paper describes a simple gas chromatographic method for quantification of ethanol in distillates of chocolate shell pralines and fillings. The samples were prepared in two steps. The first step consisted of ethanol distillation from the product and the second involved capillary gas chromatography of 10% v/v distillate with expected ethanol content between 0.06% and 2.5% w/w. Quantification ...
