  • Which phthalates are classified as priority organic pollutants?
  • From the group of phthalates, six compounds are classified as priority organic pollutants: dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate (DBP), benzyl butyl phthalate (BBP), di-2-ethyl hexyl phthalate (DEHP), and di-n-octyl phthalate (DOP) [ 6, 7 ].
  • Which phthalates are used to produce a phthalate CRM?
  • In order to produce a phthalate CRM, pure organic substances (POS) of the following phthalates were purchased: DMP, DEP, DBP, BBP, DEHP, and DOP (Sigma-Aldrich, Germany) with the declared purity from 98.4% to 99.8% (Table 3 ). The POS were studied using the analytical equipment included in the GET 208–2019. 1
  • What is the mass fraction of VOCs and RSCS in phthalates?
  • As a result of the studies performed, it was found that the mass fraction of the sum of VOCs and RSCs in phthalates ranged from 0.17% to 1.12%. The mass fraction of water was measured according to a conventional procedure using coulometric Karl Fischer titration.
  • What are phthalates used for?
  • Phthalates are most widely used as plasticisers in polyvinyl chloride (PVC) products obtained during the production of various polymeric materials for industrial, household, food, and medical purposes.
  • What is the content of water impurities in phthalates?
  • The content of water impurities in the investigated phthalates ranged from 0.027% to 0.105%. To measure the content of non-volatile impurities, the gravimetric method was used, which consisted in measuring the mass of a sample before and after the evaporation of the major component (MC) and other volatile organic and inorganic substances.
