“…For example, trifluoromethylarsine [420-42-8], CH 2 AsF 3 , has been obtained in 98% yield from trifluoromethylarsonous diiodide [353-91-3], CF 3 AsI 2 , by using coppercoated zinc and hydrochloric acid: (23). Electrolytic reduction has also been used to convert arsonic acids to primary arsines (24).…”

Arsenic is the third member of the nitrogen family of elements. In the majority of arsenic compounds the arsenic atom is in the tetrahedral valence state. A variety of inorganic and organic compounds are used in commerce, however, arsenic trioxide is the most consumed of all the compounds. China is the world leader in arsenic trioxide production. This article gives physical properties, preparation, and uses of many inorganic compounds of arsenic, eg, halides, hydrides, oxides, acid, and sulfides, and organic compounds, eg, arsines, haloarsines, diarsines, arsenin, arsonic acid, and arsine oxides. Arsenic compounds must be considered extremely poisonous. Arsenic compounds are used in fertilizers, herbicides, preparation of wood preservative (CCA), fireworks, insecticides, and pharmaceuticals.

“…In organic solvents the product is formed as an amorphous powder or as transparent mica-like flakes [310], depending on the type of solvent. Well-defined, low molecular oligomers -the smallest [326], [327] being a cage of 8 silicon atoms arranged at the corners of a cube with 12 oxygen atoms forming the bridges along the edges -can be prepared by hydrolysis in a two-phase system [328][329][330].…”

Amorphous silica, a three‐dimensional, inorganic polymeric silicon dioxide, SiO 2 , does not have a crystalline structure as defined by the absence of definitive lines in x‐ray diffraction measurements. Amorphous silica can be naturally occurring or synthetic, and either anhydrous or surface‐hydrated with silanol groups. Synthetic amorphous silica can be divided into microamorphous silica and vitreous silica (glass) made by fusing quartz at temperatures greater than approximately 1700°C. A discussion of microamorphous silica is presented, including colloidal silica, ie, sol or stable dispersion of discrete particles; silicas gelled or precipitated from solution; and pyrogenic and fused silica. Amorphous silica is characterized by chemical composition, physical properties, and characteristics of its particles, with exact analytical procedures depending on the type and application. Various methods to prepare and characterize each type of amorphous silica, commercial applications including principal global manufacturers, and health and safety issues are discussed.
