Pure phosphine is odourless. We develop produce and distribute high quality pharmaceuticals, intermediates, special chemicals and OLED intermediates and other fine chemicals. The reaction that caused the fumigant aluminum phosphide to turn into deadly phosphine is one of the most elementary in chemistry—the acid-base reaction, also known as neutralization. 104.1.1 Physical Properties. Reaction with strong acids leads to $\ce{PH4+}$ which has similar structure to the ammonium ion. Results and discussion Influence of primary phosphine structure on the phosphane­ ene reaction Air-stable primary phosphines 1 and 5 were synthesized according to literature procedures,15,26 and 2­3 were synthesized to further examine the reactivity of phosphines possessing the H2P(C3H6)SR functionality (see Experimental for details).
