[en] The mechanism and kinetics of pickling of metal films of vanadium and chromium subgroup in halogen-containing discharge are considered. It has been found out that for metals of chromium subgroup oxygen additions increase their pickling rate both in chlorine and fluorine-containing discharge. On the contrary, for metals of vanadium subgroup the increase of pickling rate with oxygen additions is observed only in fluorine-containing discharge, in chlorine-containing discharge the rate of the process decreases

[en] The irreducible cyclic representations of the monodromy matrices algebra, corresponding to the R-matrix of the six-apical model, are considered. The Baxter Q-operator in the roots from the Baxter operators unit may be represented as the trace of the tensor product of the L-operators, meeting one of such representations. The TQ equation is equitable for it. The new algebraic structure, formed by these L-operators and consequently by the Q-operators, is found

Рассмотрены неприводимые циклические представления алгебры матриц монодромии, соответствующие R-матрице шестивершинной модели. В корнях из единицы Q-оператор Бакстера может быть представлен как след тензорного произведения L-операторов, отвечающих одному из таких представлений. Для него справедливо TQ-уравнение. Найдена новая алгебраическая структура, образуемая этими L-операторами и, как следствие, Q-операторамиJournal

[en] The results of the rapeseed and palm oils transesterification with supercritical methanol and ethanol were presented. The studies were performed using the experimental setups which are working in batch and continuous regimes. The effect of reaction conditions (temperature, pressure, oil to alcohol ratio, reaction time) on the biodiesel production (conversion yield) was studied. Also the effect of preliminary ultrasonic treatment (ultrasonic irradiation, emulsification of immiscible oil and alcohol mixture) of the initial reagents (emulsion preparation) on the stage before transesterification reaction conduction on the conversion yield was studied. We found that the preliminary ultrasonic treatment of the initial reagents increases considerably the conversion yield. Optimal technological conditions were determined to be as follows: pressure within 20-30 MPa, temperature within 573-623 K. The optimal values of the oil to alcohol ratio strongly depend on preliminary treatment of the reaction mixture. The study showed that the conversion yield at the same temperature with 96 wt.% of ethanol is higher than with 100 wt.% of methanol. -- Highlights: → The results of the rapeseed and palm oils transesterification with supercritical methanol and ethanol were presented. → The effect of reaction conditions (temperature, pressure, oil to alcohol ratio, reaction time) on the biodiesel production (conversion yield) was studied. → Transesterification of vegetable oil with supercritical alcohols. → Effect of temperature and pressure on conversion yield. → Preliminary ultrasonic treatment of the vegetable oil+methanol mixture.
