The results of parametric tests of a centrifugal bubble singlet-oxygen generator based on the reaction of chlorine with an
alkaline hydrogen peroxide solution have been given. The utilization of chlorine grows with bubble-layer height, whereas the
relative content of O2(1Δ) remains constant. Growth in centrifugal acceleration leads to a more efficient utilization of chlorine. A specific oxygen
output of more than 1 mmole·cm−2·sec−1 from the bubble layer for a degree of chlorine utilization of ∼95% and a singlet-oxygen yield of more than 50% has been attained.
It has been shown that a centrifugal bubble singlet-oxygen generator is an efficient energy source for an oxygen-iodine laser.

The method of daily ration reproduction was used to study the actual nutrition of 25% of male subsampling comprising 674 subjects, during the epidemiological investigation of unorganized male population in a region of Ufa. The results of the study have shown that the caloric value of their nutrition does not exceed the established standards and is diminished with age. Protein consumption meets the physiological requirements, animal proteins prevail in their structure. Carbohydrate consumption is low, mainly at the expense of starch, while the share of sugar is high. Fat consumption exceeds the values recommended, mainly at the expense of saturated fatty acids. Cholesterol consumption is excessive. The established nutrition imbalance of the main food substances has evidenced the atherogenic character of the population nutrition, prevalence of animal food products in its structure, that should be taken into consideration when measures for the prevention of coronary heart disease are elaborated. 相似文献

The chlorine utilization efficiency and singlet oxygen concentration are determined as functions of the chlorine flow rate, the base concentration, and the flow rate and temperature of basic hydrogen peroxide in a singlet oxygen generator based on the reaction of chlorine with filament-guided descending basic hydrogen peroxide jets. The effluent gas, without aerosol entrainment, contains about 10% residual chlorine and more than 60% singlet oxygen. 相似文献

Several aminoimidazolines and their derivatives are produced from di-and polypropylene polyamines and higher isomeric acids.
Varying of the composition and ratio between the components of preparative form enabled us to produce a water-soluble corrosion
inhibitor that effectively protects steel against hydrogenation and corrosion in hydrogen sulfide media.

Power optimization of small-scale chemical oxygen-iodine laser withjet-type singlet oxygen generator

Studies of power optimization of a 5-cm gain length chemical oxygen-iodine laser (COIL) energized by a jet-type singlet oxygen generator (JSOG) are presented. For 10 mmol/s of Cl2 flow rate, output power of 132 W with chemical efficiency of 14.5% was obtained without a water vapor trap, 163 W and 18% were achieved when coholed (173 K). He was introduced downstream of the JSOG; under these conditions, the small-signal gain was estimated to be 0.32% cm-1 . 190 W and 10.5% were obtained for 20 mmol/s of CI2 flow rate. Replacing He by N2 as a buffer gas resulted in a 13% power decrease only. The main key for increasing the chemical efficiency of a COIL without a water vapor trap for a given iodine-oxygen mixing system is found to be high oxygen pressure and low water vapor pressure inside the reaction zone of the JSOG. The last goal was achieved by optimizing the composition and temperature of the basic hydrogen-peroxide solution (BHP). The experimental results are discussed and related to the composition and flow conditions of the gaseous reactants and of the BHP 相似文献
