WebSynthesis of Arsine. Arsine is formed whenever nascent hydrogen is released in the presence of arsenic or by action of water on a metallic arsenide. The formation of arsine can be described with the help of the following reaction (Anthonis et al., 1968; Coles et al., 1969): WebThe synthesis of GaInAs, like that of GaAs, most often involves the use of arsine (AsH 3), an extremely toxic gas. Synthesis of InP likewise most often involves phosphine (PH 3). Inhalation of these gases neutralizes oxygen absorption by the bloodstream and can be fatal within a few minutes if toxic dose levels are exceeded.
