  • High temperature, catalytic Friedel-Crafts synthesis of benzene phosphorus dichloride
    Patent number: 5698736
    Abstract: Benzene phosphorus dichloride can be prepared by the reaction of benzene and phosphorus trichloride in the presence of a catalytically effective amount of a Friedel-Crafts catalyst, such as aluminum trichloride or ferric trichloride, at elevated temperature, such as from about 200.degree. C. to about 250.degree. C., and superatmospheric pressure, such as no less than the vapor pressure of the components at the chosen reaction temperature, to insure a liquid reaction medium.

  • Manufacturing method for alkyldihalogenophosphines
    Patent number: 4857238
    Abstract: A manufacturing method for an alkyldihalogenophosphine uses an alkyl halide and a trihalide of phosphorus as starting materials. A reaction product which is formed by an FC reaction is reduced by yellow phosphorus in the presence of iodine, whereby an alkyldihalogenophosphine is manufactured. A high-purity alkyldihalogenophosphine can be manufactured with a high yield by using an excess amount of a trihalide of phosphorus, which can act as a reaction solvent.
