Увеличение объемов производства этилового спирта в России возможно только путем расширения рынка его сбыта. Основным критерием вхождения в новые рынки - топливный биоэтанол, органические растворители - является конкурентная цена на стадии получения спирта. An increase in the production of ethyl alcohol in Russia is possible only by expanding the market for its sales. The main criterion for entering new markets: fuel bioethanol, organic solvents, is a competitive price at the stage of alcohol production.

The main quantity of the produced ethyl alcohol is consumed by the food industry as a basis for the manufacture of alcoholic beverages, pharmaceuticals and other alcohol-containing products. In addition to food production, ethyl alcohol is widely used in medicine, perfumery, and other industries. The actual problem of alcohol production is finding ways to reduce the cost of raw materials and energy resources but still getting the world quality standard of alcohol. The best solution to the problem is to improve the technological schemes of rectification plants. For this, information was updated on modern schemes and methods for obtaining rectified alcohol. During the research, and information search was carried out in Russian and English language literary sources. A comparative analysis of books, manuals and articles on this topic was carried out, as well as the GOSTs requirements for rectification columns over the past few years were studied. The main components of rectification units were considered: contact devices (types of plate and packed devices) and rectification columns (applied pressure: atmospheric, vacuum, under a certain pressure; and their total number).Progressive schemes used in modern alcohol production in Russia and abroad (Ukraine, USA, France, Finland) were considered. Based on the received data, the following conclusions were formulated: the most effective types of contact devices are sieve and valve trays, among the packing there are Raschig rings, a promising type of columns is disc-type, the most popular scheme for the operation of a rectification plant is a combination of work under pressure and vacuum.

ObjectivesThere is sufficient evidence for a causal association of sinonasal epithelial cancers (SNEC) only for exposure to wood and leather dusts, nickel compounds and employment in isopropyl alcohol production. The aim of this study was to assess whether other occupational hazards are associated with the risk of SNEC for the main histologic types, namely adenocarcinoma (AD) and squamous cell carcinoma (SCC).MethodsThe study population included 375 incident SNEC cases collected from 1996 to 2014 (79% of all diagnosed SNEC) throughout the Piedmont region by the regional Sinonasal Cancer Registry, and 408 hospital controls. Exposure to 17 occupational agents was assigned through expert assessment based on interviews to the subjects on jobs held throughout their working life. The relationship of SNEC with ever and cumulative exposure to the hazards was assessed through unconditional logistic regression models adjusted for age, sex, area of residence, smoking habit, year of enrolment and coexposures.ResultsAD was associated with both ever and cumulative exposure to wood dust, leather dust and organic solvents, and with cumulative exposure to textiles dusts. SCC risk was significantly increased by ever exposure to nickel, chromium and welding fumes, as well as by cumulative exposure to welding fumes, arsenic and organic solvents. A mixed group of other histological types was associated with both ever and cumulative exposure to wood dust and textile dusts.ConclusionsThe associations of SNEC with wood dust, leather dust and nickel were confirmed, while some new associations were observed for other hazards, which merit further investigation.

1. At the imaginal ecdysis of Calliphora erythrocephala (Meigen) the initiation of normal hardening and darkening is brought about by the release into the blood of an active factor (Cottrell, 1962b). 2. The darkening factor can be detected in fly blood by injecting it into flies decapitated at the moment of emergence. Blood taken from flies at the moment of emergence or 24 hr. after expansion produces little or no reaction, although blood taken between 3 min. and 10 hr. after emergence shows darkening activity. However, extracts of other tissues and many chemicals will also induce darkening though probably unspecifically through damage effects. The assay can therefore be used certainly only for detecting activity in fly blood. 3. The blood-borne darkening factor of blowflies will withstand boiling for 10 min. or drying at 120° C. for 20 min., but it does not retain its activity when kept in solution at room temperature for more than 24 hr. It is non-dialysable, relatively insoluble in organic solvents and is inactivated by ethyl alcohol and the bacterial protease subtilisin. It is probably proteinaceous and is certainly not tyrosine or any of the phenolic compounds at present thought to act as the precursors of the tanning agent. 4. The blood-borne factor of different blowflies (Calliphora, Sarcophaga and Lucilia) is not species-specific and there is some inconclusive evidence that a similar factor is present at the ecdysis of Schistocerca.

Triticale accounts for the biggest share in gross processing and state procurement of grain in Belarussian production of alcohol. The main difficulty in its processing is the formation of viscous technological fluids due to the presence of non-starch polysaccharides in its chemical composition. All measures taken to solve the problem come down to the selection of the efficient enzyme preparations, hydrolyzing grain polymers into low molecular weight compounds, which have the ability to be disposed by the yeast cells and form the ethyl alcohol. But grain own enzymes are not involved. It is possible to solve the problem by means of biological activation, which will activate grain enzyme systems and partially hydrolyze grain polymers into low molecular weight compounds. The article considers general and special technological parameters of six cultivars of triticale selected in the Republic of Belarus: Antos, Kastus, Dubrava, Run, Prometheus, Impulse. The authors determined that the most promising cultivars for bioactivation and food grade ethyl alcohol production are Antos and Dubrava. The authors explored the possibility of using hot soaking of triticale grain for the biological activation. They also showed the advantages of introduction of amaranth green mass in the amount of 8% during hot soaking for the reduction of grain microbiological contamination. They studied the changes in the technological properties of triticale cultivars Antos and Dubrava after the bioactivation with the green mass of amaranth. The authors determined that grain microbiological characteristics improved, the activity of grain enzymes increased, proportion of low molecular weight compounds in the chemical composition increased. They studied the processes taking place during wort and mash production from the bioactivated triticale grain. The authors showed that the processing of bioactivated triticale grain resulted in the production of wort with higher concentration of dry matter which allowed to increase the ethanol content in the mature mash produced from triticale cultivar Antos by 19.5% and from the triticale cultivar Dubrava by 29.3% and reduce the total quantity of the main impurities in distillates.
