General Description

Phosphonic acid, phenyl-, bis(2-chloroethyl) ester is a chemical compound commonly known as bis(2-chloroethyl) phenylphosphonate. It is an organophosphate compound used in the production of nerve agents and insecticides. This colorless or slightly yellow liquid is a highly toxic and reactive compound that can cause severe health effects upon exposure, including irritation to the skin, eyes, and respiratory system, as well as damage to the nervous system. It is classified as a Schedule 2 compound under the Chemical Weapons Convention due to its potential use as a chemical warfare agent. The compound is primarily used in the production of nerve agents such as Sarin and Soman, which are extremely potent and deadly chemical weapons. Due to its use in the production of nerve agents, bis(2-chloroethyl) phenylphosphonate is highly regulated and controlled under international law.

Phenyl phosphonic acid dihalogen ethyl ester compound and preparation method thereof

The invention relates to a phenyl phosphonic acid dihalogen ethyl ester compound and a preparation method thereof. The formula of the phenyl phosphonic acid dihalogen ethyl ester compound is shown as follows, wherein X is Cl or Br. The preparation method includes: allowing phenyl phosphonic acid dimethyl ester and halohydrin to react under the presence of catalyst or allowing phenylphosphonic dihalogen to react with ethylene oxide in organic solvent, and purifying to obtain yellowish sticky liquid phenyl phosphonic acid polyester. The fire retardant contains phosphorus and halogen which are fire-retardant elements, a good synergic fire-retardant effect is achieved, a good plasticizing effect is achieved, and the fire retardant is suitable for being used as the fire-retardant plasticizer of materials such as PVC (polyvinyl chloride), polyurethane, epoxy resin and unsaturated resin. The preparation method is simple in process, high in yield, free of hydrogen chloride pollution, low in equipment investment and easy in large-scale production.

Conversions of 2-phenyl-1,3,2-dioxaphospholane under the action of hydrogen chloride

The reaction of 2-phenyl-1,3,2-dioxaphospholane with HCl gives a mixture of phenylphosphinic acid, bis(2-chloroethyl) phenylphosphonate, and phenylphosphine; therewith, intermediate oligomeric phosphonites, hydrophosphoryl compounds, and phosphoranes were detected. Thermal treatment of the reaction mixture results in formation of ethylene phenylphosphonate and (2-chloroethyl)phenylphosphinate.
