The present invention primarily relates to a process for producing methyldichlorophosphane (MDP) by reaction of methane with PCl.sub.3 (phosphorus trichloride) in the presence of a catalytically active amount of a compound of formula SO.sub.xCl.sub.2, wherein the index x may take the value 1 (SOCl.sub.2, thionyl chloride) or 2 (SO.sub.2Cl.sub.2, sulphuryl chloride). The present invention further relates to particular mixtures that are particularly suitable for producing methyldichlorophosphane (MDP) in the context of the process according to the invention/that are formed when carrying out a process according to the invention.

An object of this invention is to provide a simple method for producing sulfur tetrafluoride. The object is achieved by a method for producing sulfur tetrafluoride, comprising step A of reacting a fluorinated halogen compound with sulfur chloride, the fluorinated halogen compound being represented by formula: XF.sub.n, wherein X is chlorine, bromine, or iodine; and n is a natural number of 1 to 5.

Diffusion and infusion resistant implantable devices and methods for reducing pulsatile pressure are provided. The implantable device includes a balloon implantable within a blood vessel of a patient, e.g., the pulmonary artery. The balloon is injected with a fluid mixture comprising a constituent fluid(s) and a diffusion-resistant gas to provide optimal balloon volume and limit fluid diffusion throughout multiple cardiac cycles. The fluid mixture may be pressurized such that the balloon is transitionable between an expanded state and a collapsed state responsive to pressure fluctuations in the blood vessel.
