1. A method for producing a product comprising a fluoroethane, wherein the fluoroethane is 1,1,2-trifluoroethane,
the method comprising obtaining the product comprising the fluoroethane from a fluoroethylene comprising chlorotrifluoroethylene, wherein the fluoroethylene is represented by the following formula (3) by a reaction in the presence of catalysts:
CX9F═CX10X11 (3),
wherein X9, X10, and X11 are the same or different and each represents a hydrogen atom, a fluorine atom, or a chlorine atom,
wherein each catalyst is formed by supporting a noble metal on a carrier;
a reactor for performing the reaction is filled with a catalyst having a noble metal concentration of C1 mass % based on the entire catalyst, and a catalyst having a noble metal concentration of C2 mass % based on the entire catalyst to form an upstream portion and a downstream portion, respectively, C1<C2, 0.01≤C1≤10, and 1≤C2≤15;
the reaction is performed by bringing the fluoroethylene represented by formula (3) and hydrogen gas into contact with the upstream portion and the downstream portion in this order, and
the product comprising trifluoroethylene in an amount of 40 mol % or less based on the total amount of the product.
