NI, CR, PB IN HYDROMORPHIC SOILS OF THE TEREK-SULAKSKOY SUBPROVINCE OF DAGESTAN

abstract 0761202017 issue 76 pp. 196 – 205 29.02.2012 ru 1653
In the article, we investigated hydromorphic soils of the Tersko-Sulak subprovince of Dagestan. We determined the content of humus, nickel, chromium and lead with genetic horizons of the investigated soils. The small excess of the maximum allowable concentration of nickel and chromium has been found, doze of lead was within norm

THE DIPOLE MOMENTS AND THE STRUCTURE OF THE FOUR-MEMBERED CLOSED-CHAIN ARSENIC COMPOUNDS

abstract 0781204020 issue 78 pp. 234 – 243 30.04.2012 ru 1178
By the method of dipole moments, there has been determined that the tri-coordinated arsenic derivatives (p-XC6H4AsN-R)2 with R= Bu-t in the liquor exist in a cis-form, as for R=С6Н4Х-p the trans-structure is being realized. As for tetra-coordinated derivatives [XC6H4As(S)NBu-t]2 the trans-form is also beeing observed. For ortho-substituted connections, the angles of flat surfaces rotation of benzene rings have been defined

INCREASING ENVIRONMENTAL SAFETY OF PRODUCT RECYCLING OIL SLUDGE

abstract 0781204064 issue 78 pp. 806 – 815 30.04.2012 ru 1793
In this article, the recycling problem of oil sludge on some modern refinery factories is observed. We studied physical and chemical structure of oil sludge and offered a new way of neutralization of oil sludge. It is established, that if we replace a carbon sorbent to sorbent that contains silica for oil sludge neutralization, we will get environmental safe product. As such sorbent, which contains silica we offer to use a burnt rice peeling. For practical realization the way of neutralization is developed and technological scheme which allows to save natural resources (hydrocarbons and water) and return it to production cycle and to recycle the petropolluted sludge is offered

ABOUT COMPARATIVE POLARITY OF As=N AND P=N GROUPS

abstract 0781204019 issue 78 pp. 222 – 233 30.04.2012 ru 1542
By the method of the dipole moments the connections of (p-XC6H4)3As=N-C6H4-Y series have been examined. The method of the vector-statistical analysis of the dipole moments helped to define the ranges and directions of the moments of (Сар)3As=N-Cар, (Сар)3As=N и N-Cар series. There has been shown that the substitution of the para-assistants X and Y in aromatic groups doesn't lead to an additional interaction influencing the electronic properties of the (Сар)3As=N-Cар group. The comparative analysis of the (Сар)3Э=N-Cар (Э=P, As) group moments specifies the essencial shift of the electron density to Сар(N) when replacing atom P to As
