- Synthesis and study of mutagenic properties of lupane triterpenoids containing 1,2,3-triazole fragments in the C-30 position
-
New derivatives of betulin, betulinic acid methyl ester, and their acetate analogs containing 1,2,3-triazole fragments in the C-30 position were synthesized. It was shown using the Ames test that 30-azidolup-20(29)-enes and 3β,28-diacetoxy-30-(4-R-1,2,3-t

- Reverse Kleiner method for manufacturing nitrogen dioxide, nitric oxide, nitric acid, metallic ascorbates and alkyl ascorbates of vitamin C
-
In this invention new chemical reactions, new chemical processes are established, and these chemical reactions and chemical processes can be used with the system designed to produce nitrogen dioxide, nitric oxide, nitric acid as well as metallic ascorbates or alkyl ascorbates, either as main or as secondary products. Ascorbic acid solution is reacted at room temperature or at elevated temperature with either sodium nitrite or potassium nitrite or calcium nitrite or alkyl nitrite such as isobutyl nitrite or barium nitrite or silver nitrite solution. All the second reactants except alkyl nitrites such as isoamyl nitrite or isopropyl nitrite or isobutyl nitrite, as well as the first reactant, ascorbic acid, are in aqueous solutions. The reaction vessel contains the ascorbic acid solution; into this solution, under, certain pressure, is delivered the choosen aqueous nitrite solution. Gas mixture of nitrogen dioxide and nitric oxide is produced by addition of the choosen nitrite solution. The generated and collected gas mixture is then mixed with oxygen, thus the nitric oxide in the gas mixture converts—by reacting with oxygen—into nitrogen dioxide, then this homogeneous gas is dissolved in water, thus giving us nitric acid. In this chemical reaction system two sets of chemical reactions take place; one on the surface of the solution(s) that produces the main part of the gas mixture, and this is the major part of the chemical reaction system. In the liquid phase of the reaction processes form the metallic ascorbates as well as the alkyl ascorbates. All the same can be done with isoascorbic acid; the chemical reactions will go somewhat slower.

- Process for preparing ascorbic acid
-
Process for preparing pure ascorbic acid from 2-keto-L-gulonic acid or its sodium salt, by carrying out the following successive steps: esterification of 2-keto-L-gulonic acid or its sodium salt lactonization to sodium ascorbate optional separation of the sodium ascorbate displacement of the ascorbic acid from its salt separation of the sodium sulphate separation and purification of the ascorbic acid from its methanolic or aqueous-methanolic solution.

- Process for the production of sodium or potassium L-ascorbate
-
In the process described for the production of sodium or potassium L-ascorbate, 2-keto-L-gulonic acid monhydrate is esterified with methanol. The esterification is only partial, that is, is not carried out until the esterification equilibrium is reached.
