Usage

Uses

Used in Chemical Warfare:
Phosphonic acid, phenyl-, bis(2-chloroethyl) ester is used as a precursor in the production of nerve agents such as Sarin and Soman for their extreme potency and deadliness as chemical weapons.
Used in Pesticide Industry:
Phosphonic acid, phenyl-, bis(2-chloroethyl) ester is also used as an ingredient in the formulation of certain insecticides, contributing to their effectiveness in controlling pests.
Due to its highly regulated and controlled status under international law, the use of bis(2-chloroethyl) phenylphosphonate is limited to specific applications that are strictly monitored to prevent its misuse in chemical warfare.

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.

Transformations of bis(2-chloroethyl) arylphosphonites in the presence of haloacetic acid esters

The reaction of aryl(dichloro)phosphines with (2-chloroethoxy)trimethylsilane in the presence of haloacetic acid esters was studied with the goal of developing a new method for the synthesis of ethyl [(2-chloroethoxy)(4-dimethylaminophenyl)phosphoryl]acet

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.

Reaction of dichlorophosphines with glycidol. New data on the transformations of cyclic phosphonates

Reaction of dichlorophosphines with glycidol yields 2-R-4-chloromethyl-1,3,2-dioxaphospholanes as primary products, which under the reaction conditions or under the action of HC1 surprisingly readily undergo redox transformations yielding 2-R-4-chloromethyl-1,3,2-dioxaphospholane 2-oxides, dichloropropyl R-phosphinates, bis(dichloropropyl) R-phosphonates, and phosphines RPH2.
