The addition of 1000–4000 wpm (weight parts per million) of a low molecular weight hydrocarbon (methane or ethane) has been suggested as a corrosion inhibitor to the hydrogen propellant in nuclear rockets. For this purpose it would be convenient if a storable and/or flowable suspension of such a hydrocarbon in liquid hydrogen could be produced. Because several observers [1,2] have seen liquid hydrogen made “milky” with an unwanted hydrocarbon impurity in the receiver of a Joule-Thomson liquefier, it was proposed to operate a liquefier using a feed gas containing the required amount of methane or ethane and to study the product. Other methods of producing the suspension were also tried, but were neither sufficiently promising nor of sufficient interest to warrant reporting here. These included injecting the condensable gas above and below the surface of liquid hydrogen in a dewar and into flowing liquid hydrogen.
