Arsenic Catalysts

Arsenic and phosphine have very similar physicochemical properties, and arsenic catalysts have unique applications in catalyzing some organic chemical reactions. For example, an arsenic heterocycle is used as a homogeneous catalyst to catalyze the hydroboration of an aldehyde. In addition, arsenic catalysts can also catalyze the synthesis of polyester in polymer chemistry.

Alfa Chemistry can provide you the arsenic catalyst. Alfa Chemistry scientists have the expertise to support the catalysts you need. At the same time, our laboratory has advanced equipment to ensure timely and efficient synthesis of arsenic catalysts. We work closely with universities and private companies to meet the needs they need.

  • Arsenic catalyst is used for hydroboration: The hydroboration of unsaturated systems has widespread applications in in synthetic laboratories and in the chemical industry. Arsenic catalysts are one of the few non-metallic catalysts that can catalyze such reactions. Compared with traditional metal catalysts, arsenic heterocyclic catalysts have mild reaction conditions and shorter reaction time.

  • Arsenic catalyst is used for polymerization: The polymerization step in the preparation of fiber forming polyesters is conducted in the presence of catalytic amounts of a novel polycondensation catalyst comprising arsenic ethylene glycoloxide. Many catalysts have been proposed to accelerate the reaction between dibasic acids and glycols. A disadvantage of these catalysts is that they can contaminate the diol used and cause problems with diol recovery and recycle in commercial operations. The arsenic catalyst can reduce the reaction time in producing a synthetic linear polyester from a dibasic acid and a glycol with satisfactory physical properties directly and readily. In addition, the use of an arsenic catalyst can reduce the glycol contamination in the reaction and increase the ease of recycling the glycol if desired.
