What is Methylphosphonyl difluoride used for?
It is used for production of sarin and soman as a component of binary chemical weapons; an example is the M687 artillery shell, where it is used together with a mixture of isopropyl alcohol and isopropyl amine, producing sarin….Methylphosphonyl difluoride.

What is DF sarin?
DF, a clear, non-flammable liquid, has a strong acid-like odor. The compound can be combined with a second component to form the nerve agent sarin (GB). To destroy DF, operators add water to react with DF.

How is oxygen difluoride used?
Oxygen Difluoride is a colorless gas or a yellowish-brown liquid with a foul odor. It is used as an oxidizer in rocket fuel systems. * Oxygen Difluoride is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT and NIOSH.
How is dioxygen difluoride made?
Dioxygen difluoride, O2F2, is a yellow-orange solid melting at −163 °C. It is prepared by the reaction of O2 and F2 mixtures under glow discharge at −180 to −190 °C.
Is methylphosphonyl difluoride a chemical?
Methylphosphonyl difluoride is listed in the CWC Annex on Chemicals under Schedule 1 (1). (1) Organization for the Prohibition of Chemical Weapons; Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and Their Destruction.
What is the half life of methylphosphonyl difluoride in air?
If released to air, a vapor pressure of 36 mm Hg at 25 °C indicates methylphosphonyl difluoride will exist solely as a vapor in the atmosphere. Vapor-phase methylphosphonyl difluoride will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 236 days.
Does methylphosphonyl difluoride absorb sunlight?
Methylphosphonyl difluoride does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight. If released to soil, methylphosphonyl difluoride is expected to have very high mobility based upon an estimated Koc of 1.
How is difluoro deposited in the respiratory system?
The deposition of inhaled difluoro was mainly in the maxillo- and ethmoturbinates, and clearance was mainly by mucociliary clearance and swallowing. Constants were calculated for relating doses of difluoro to various respiratory tract tissues as a function of total deposited vapor.
