PROBLEM TO BE SOLVED: To provide a non-chlorine type having an appropriate viscosity and solubility in a base oil, a high sulfur content, excellent load bearing performance and oxidation stability when used as an extreme pressure additive, and excellent non-ferrous metal low corrosion resistance A non-chlorinated sulfurized olefin having good load bearing performance and oxidation stability and excellent non-corrosive corrosion resistance, and a method for producing the sulfurized olefin. a process for producing a sulfurized olefin (A) by reacting a1), sulfur (a2), hydrogen sulfide (a3) and amines (a4) to obtain a sulfurized olefin (A), a mixture of two or more dienes (a1) The sulfur atom number in the molecule is 1 to 3 and the sulfur content in the molecule is 40 to 40, obtained by reacting sulfur, sulfur (a2) and hydrogen sulfide (a3). 55 weight In it, sulfurized olefin containing no chlorine substantially.
