One of the plasticizers, i.e. substances that reduce intermolecular interactions and increase the mobility of polymer chains. Plasticizers cause reducing the vitrification temperature, hardness and increase flexibility. Di-2-ethylhexyl phthalate, called dioctyl phthalate, is obtained by esterifying phthalic anhydride with 2-ethylhexyl alcohol, otherwise octanol. Dioctyl phthalate is widely used as a polyvinyl chloride plasticizer. Used mainly in the processing of plastics as a plasticizer, and in the paint and varnish industry.
