Abstract: 본발명에따른연료복합첨가제는높은습도, 낮은온도, 장기간방치등의열악한환경조건에서도상분리현상을현저히지연시킬수 있는효과가있고, 보다낮은어는점을가져겨울철결빙을방지하는효과가있을뿐만아니라, 엔진내에고착화된불순물들에대한세정효과가우수한장점이있다. 또한연료외의용도에사용되어치명적인문제를일으키지않도록, 예컨대음료로사용될수 없도록하는효과가있다.

Abstract: PURPOSE: A composition for sulfur free odorant is provided to prevent metal corrosion of the odorant with chemical stability, and to produce the composition having small exhaust gas such as sulfurous acid gas etc. CONSTITUTION: A composition for sulfur free odorant includes one or more selected from (C1~C5)alkyl isovalerate in a chemical formula 1, one or more selected from an acrylate-based compound in a chemical formula 2, and one or more selected from a nitrogenous compound in a chemical formula 3. One or more selected form the compound of the chemical formula 2 is used in a weight ratio of 3~7 : 7~3 with one or more selected from the (C1~C5)alkyl isovalerate. One or more selected from the nitrogenous compound is used in the weight ratio of 1 : 0.01 ~ 0.5 with the one or more selected from the (C1~C5)alkyl isovalerate.
