PURPOSE:A phthalic acid-type plasticizer capable of improving cold and heat resistance of non-rigid vinyl chloride products, obtained by reacting a specific alcohol derived from an 8C alcohol according to the oxo process with phthalic acid. CONSTITUTION:An olefin mixture comprising (a) 3 wt.% or more, preferably 7-20 wt.% of an olefin having one isobutane skeleton in the molecular chain and (b) 3 wt.% or less of, preferably no olefin having a quaternary carbon atom is subjected to the oxo reaction to form an alcohol. The resulting alcohol is reacted with phthalic acid to give a phthalic acid-type plasticizer. EFFECT:The plasticizer can impart improved cold and heat resistance to automobile or high-class leather while maintaining the plasticizing effect and electrical resistance equal to those of dioctyl phthalate. |
