Arsenic tribromide is a highly water soluble crystalline arsenic source for uses compatible with bromides and lower (acidic) pH. Most metal bromide compounds are water soluble for uses in water treatment, chemical analysis and in ultra high purity for certain crystal growth applications.
IUPAC Nomenclature ensures that each compound (and its various isomers) have only one formally accepted name known as the systematic IUPAC name. However, some compounds may have alternative names that are also accepted, known as the preferred IUPAC name which is generally taken from the common name of that compound.
Preferred IUPAC name. Bromoethene. Other names Vinyl bromide 1-Bromoethene ... Solubility in water. Insoluble log P: 1.57 Vapor pressure: 206.8 kPa at 37.8 °C
This colourless liquid is prepared by treatment of arsenic(III) oxide with hydrogen chloride followed by distillation: As 2 O 3 + 6 HCl → 2 AsCl 3 + 3 H 2 O. It can also be prepared by chlorination of arsenic at 80–85 °C, but this method requires elemental arsenic. [4] 2 As + 3 Cl 2 → 2 AsCl 3
Preferred IUPAC name. 1-Bromopyrrolidine-2,5-dione. Other names N ... It can be purified by recrystallization from 90 to 95 °C water (10 g of NBS for 100 mL of water
Activated sludge tank at Beckton sewage treatment plant, UK.The white bubbles are due to the diffused air aeration system. The activated sludge process is a type of biological wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa.
Arsenic trioxide is indicated in combination with tretinoin for treatment of adults with newly-diagnosed low-risk acute promyelocytic leukemia whose acute promyelocytic leukemia is characterized by the presence of the t(15;17) translocation or PML/RAR-alpha gene expression; and for induction of remission and consolidation in patients with acute promyelocytic leukemia who are refractory to, or ...
The reaction of boron trichloride with alcohols was reported in 1931, and was used to prepare dimethoxyboron chloride, B(OCH 3) 2 Cl. [3] Egon Wiberg and Wilhelm Ruschmann used it to prepare tetrahydroxydiboron by first introducing the boron–boron bond by reduction with sodium and then hydrolysing the resulting tetramethoxydiboron, B 2 (OCH 3) 4, to produce what they termed sub-boric acid.
