DEHT is an ortho-phthalate alternative. DEHT is not considered to be a part of the common "phthalate ester" class, as it is not ortho-substituted. DEHT is compatible with use in cellulose acetate-butyrate, cellulose nitrate, polymethyl methacrylate, polystyrene, polyvinyl butyral, and PVC resins (CPSC 2010). DEHT is manufactured by combining terephthalic acid with 2-ethylhexanol followed by purification via distillation (UNEP 2003).
