摘要： 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.
