چکیده

Dorogov’s antiseptic stimulators (fractions 2 and 3) are products of meat bone meal pyrolysis that used to treat farm animals. However, there is a lack detailed information about their chemical composition. We aimed study individual compositions organic substances in the water- oil-soluble condensates these preparations.
 ASD-2F ASD-3F (Agrovetzashchita, Russia) were as samples pyrolysis. Volatile identified by gas chromatography chromatography-mass spectrometry, while amino acids determined high-performance liquid chromatography.
 The initial water-soluble condensate contained ammonium salts, amides carboxylic acids, N-heterocyclic compounds, hydantoins, dipeptides, with total content 8% condensate’s weight. Its dehydrated concentrate had almost no salts but its contents lowvolatile nitrogen-containing heterocycles 10–15 times high those condensate. 13 dipeptides 19 2.5%. According oilsoluble over 30% nitriles; 7–10% higher aromatic hydrocarbons, phenols, (with esters); 1–3% naphthalenes, pyridines, dipeptides. heterocycles, well similar condensate.
 80% pyrolytic Together concentrate, they more than 220 divided into 10 main groups. consisted 350 compounds. full composition preparations can be further three-quadrupole mass spectrometry.

Pyrolysis and gasification of meat-and-bone-meal: energy balance and GHG accounting.

Meat-and-bone-meal (MBM) produced from animal waste has become an increasingly important residual fraction needing management. As biodegradable waste is routed away from landfills, thermo-chemical treatments of MBM are considered promising solution for the future. Pyrolysis and gasification of MBM were assessed based on data from three experimental lab and pilot-scale plants. Energy balances we...

Formation of liquid and solid products from liquid phase pyrolysis.

The aim of the present work was to improve the C:O ratio in biomass by preserving the lignin macrostructure of lignocellulosic feed. The intention of liquid phase pyrolysis is to liquefy biomass and prepare biomass for further upgrading steps like hydrogenation and deoxygenation. Pyrolysis was carried out in a non-aqueous liquid phase heat carrier. The process was carried out in a semi-batch re...

High-Performance Liquid Chromatographic Determination of Oxytetracycline Residue in Cured Meat Products

The development of a sensitive automated method for residue control of oxytetracycline (OTC) in cured meat (soudjouk) is described. The principle steps involve the extraction of OTC from cured meat in the presence of citric acid with nitric acid, methanol and de-ionized water, and then the determination by HPLC. In HPLC, Hypersil BDC C18 column was used and OTC was separated at 24◦C using a mob...
