    Abstract: A lower hydrocarbon having from one to eight carbon atoms is passed through an electric arc, heated therein above about 1,000* F., and immediately mixed with nitrogen or a nitrogencontaining compound, which mixture immediately reacts to form acetylene, hydrogen cyanide and other products, which products are quenched below about 1,000* F. If desired, the resulting products are further reacted to form acrylonitrile from the further reaction of the acetylene with the hydrogen cyanide present. By not passing the nitrogen-containing compound through the arc during the process, severe errosion of the electrodes is avoided. By passing only the lower hydrocarbon through the arc during the process, it is not necessary to employ any inert arc gas, which would increase the cost of operation and the difficulty of separation of products. Because of lower cost and availability, methane and ammonia are preferred as the two reactants. Nitrogen and other nitrogen-containing compounds are disclosed as suitable nitrogen sources to replace the ammonia. Apparatus features are the combination of a rotating arc heater with a fluidized bed arc effluent quench and feed preheater and, if desired, fluidized bed acrylonitrile from hydrogen and acetylene reactor followed, if desired, by a suitable series of fractionators.

    Abstract translation: 具有1至8个碳原子的低级烃通过电弧，在其上加热约1000°F，并立即与氮气或含氮化合物混合，该混合物立即反应形成乙炔，氰化氢等 产物，其在大约1000°F下淬火。如果需要，所得产物进一步反应以从乙炔与存在的氰化氢的进一步反应形成丙烯腈。 在该过程中，通过不通过含氮化合物通过电弧，避免了电极严重的侵蚀。 在该过程中，仅通过电弧通过低级碳氢化合物，不需要使用任何惰性电弧气体，这将增加操作成本和产品分离的困难。 由于成本和可用性较低，因此甲烷和氨作为两种反应物是优选的。 公开了氮和其它含氮化合物作为适当的氮源来代替氨。
