| titleOfInvention | Especially pure arsenic acid production process |
| abstract | FIELD: industrial inorganic synthesis. n SUBSTANCE: invention relates to producing arsenic acid, which serves as starting material for obtaining pure arsenic-containing substances usable as chemical power sources as well as additive in optical glass manufacturing processes. Process of invention envisages oxidation and simultaneously hydrolysis of tri-lower alkyl arsenites of general formula (RO) 3 As (R = Me, Et, Pr) with aqueous hydrogen peroxide solution at 10 to 50°C and (RO) 3 As/H 2 O 2 molar ratio 1:(1-3). Resulting reaction mass is distilled to remove alcohol water. Commercial especially pure arsenic acid is obtained after evaporation of its solution. n EFFECT: increased yield of especially pure arsenic acid, simplified production process, and increased reliability thereof. n 3 cl, 5 ex |
