An object of the present invention is to provide a dialkyl sulfide which can effectively form a metal sulfide film on a metal surface even in a low-temperature environment, has excellent storage stability, and is suitable as an extreme-pressure additive. The present invention provides a dialkyl sulfide represented by general formula (1) below (in the formula, R1 and R2 each independently represent an alkyl group, and n is an integer), wherein the content of a compound having an n value of 1 in the general formula (1) is 10.0% by mass or less relative to the total amount of compounds represented by the general formula (1)
A dialkyl sulfide represented by general formula (1) below
A method for producing a dialkyl sulfide, the method comprising a first step of reacting a monosubstituted 1-olefin compound (a) with sulfur (b) in the presence of hydrogen sulfide (c) at a molar ratio [(a)/(b)] within a range of 0.6 to 2 in a reaction system of 60° C. to 130° C.;
