The rate constants and kinetic coefficients of inhibition (fkin) for olefins oxidized with the transition metal compounds (Mn) were measured by highly sensitive microvolumometry at 323 K in combination with kinetic modeling. The cyclic mechanism of the reactions of hydroxyl radicals with Mn leading to the multiple chain termination was confirmed as indicated by the observed effect of long-term inhibition of the oxidation of the substrates with Mn and obtained values of fkin > 102.

The results are presented of the major activities undertaken by the Geodynamic Research Centre during the final stage of Boguchanskaya hydroproject construction.

It is found that the main wear-prone elements in machines for firing pellets are the coolers; changing these requires stopping the machine every 70–90 days on average, interrupting the normal course of the technological process. Repairs revealed the efficiency of the guniting method for repair of linings of firing machines, in comparison with poured concrete. The lifetimes of gunite concrete linings were 2–3 times greater: 220–240 days.

Reaction of aqueous solutions of salts of acrylic acids with thioepi chlorohydrin affords thietyl acrylates, which on hydrolysis give 3-hydroxythietane, and on oxidation with hydrogen peroxide give 3-hydroxythietane 1,1-dioxide. The diene synthesis was carried out with these acrylates, and also with acryloyl and methacryloyl isothiocyanates.
