Di- n -octyl phthalate (often imprecise dioctyl phthalate) is an organic chemical compound from the group of phthalates ( esters of phthalic acid ), which is mainly used as a plasticizer . It is a colorless, odorless, oily liquid and a structural isomer of diethylhexyl phthalate (DEHP).
Extraction and presentation
Di- n -octylphthalate is obtained by reacting phthalic anhydride with octanol in the presence of a catalyst .
properties
Di- n -octyl phthalate is a colorless odorless liquid which is practically insoluble in water.
use
Di- n -octyl phthalate is used as a plasticizer (e.g. for PVC), a component of anti-foaming agents , solvents and as a paint resin and is used for applications in the cosmetics industry, in the medical sector and in the explosives industry. It is also used in the production of test aerosols .
safety instructions
DNOP must not be used as a plasticizer for toys and baby items that children can put in their mouths because the substance is listed in Appendix 1 of the Consumer Goods Ordinance .
