Sarin gas is a highly toxic gas, belonging to the group of organo-phosphorous, whose molecular formula is C4H10PFO2. It was discovered accidentally in 1936 by Gerhard Scharader, a German chemist, during a synthesis of pesticides. This gas is found in liquid or vapor form, has a sweet odor. Its melting point is -57 ° C, boiling point 147 ° C and density 1.089 g / mL. As it is a dangerous gas, there is no disclosure of its synthesis, because if this happens it can be manufactured and used inappropriately. The phosphoric acid (H3PO4) present in the Sarin gas molecule and the temperature, are factors that accelerate the reaction of the gas, causing it to become fast.
