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.
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
Similarly, it also reacts quickly with alcohols and carboxylic acids, although less vigorously than with water. With simple Lewis bases (L), Al 2 Br 6 forms adducts , such as AlBr 3 L. Aluminium tribromide reacts with carbon tetrachloride at 100 °C to form carbon tetrabromide :
The main use for phosphorus tribromide is for conversion of primary or secondary alcohols to alkyl bromides, [9] as described above.PBr 3 usually gives higher yields than hydrobromic acid, and it avoids problems of carbocation rearrangement- for example even neopentyl bromide can be made from the alcohol in 60% yield.
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 ...
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
PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.
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.
