Polydisperse dioctyl phthalate (DOP) aerosols are employed for testing filter penetration with loading of Rand P-series particulate filters for National Institute for Occupational Safety and Health (NIOSH) certification. Penetration for filters must not exceed NIOSH allowed maximum levels during the entire loading of 200 mg DOP indicating no filter degradation. Degradation of respirators loaded...

Poly(vinylidene fluoride-hexafluoropropylene) (PVDF-HFP) porous membranes are fabricated via thermally induced phase separation (TIPS) with mixed diluent (dibutyl phthalate (DBP)/dioctyl phthalate (DOP)). The effects of mixed diluent are discussed in detail in term of morphology, mean pore size, selective wettability, etc. The results show that the membrane structure changes from spherulitic to...

Di-2-ethylhexyl phthalate (DEHP), often referred to as dioctyl phthalate or DOP, is the most widely used plasticizer for vinyl plastics, and approximately 350 million pounds were produced in the United States during 1970. Altogether the production of phthalate ester plasticizers was 855 million pounds (1). The cumulative production of DEHP and related phthalate plasticizers in the United States...

Thermooxidative degradation of poly(vinyl chloride) (PVC) is inevitable during processing of PVC. Recycling of this polymer requires reprocessing in most of the cases, and due to the low thermal stability of PVC, it is of paramount importance to reveal the effect of thermooxidation on the thermal stability of this commercially important polymer. However, detailed systematic investigations are l...

A new coated-wire electrode based on PVC membrane plasticized with dioctyl phthalate (DOP) and containing the diltiazem-tetraiodido bismuthate (III) ion association coated a silver wire was constructed used for potentiometric determination of diltiazem hydrochloride. The performance characterized optimized according to following experimental criteria: composition, soaking time, working pH range...

Since that time, new data have become available, and these have been incorporated into the monograph and taken into consideration in the present evaluation. Chem. Abstr. Name: 1,2-Benzenedicarboxylic acid, bis(2-ethylhexyl) ester IUPAC Systematic Names: Bis(2-ethylhexyl) phthalate; phthalic acid, bis(2-ethyl-hexyl) ester Synonyms: Bis(2-ethylhexyl) 1,2-benzenedicarboxylate; bis(2-ethylhexyl) or...

Jude K. Coompson, B.S. Marquette University, 2014 Benzene is a constituent component of crude oil that has been classified as a carcinogen by the EPA with a maximum contamination level (MCL) of 5ppb in drinking water. However, of the aromatic compounds, benzene has one of the lowest polymer-water partition coefficients using commercially available polymers as sensor coatings, resulting in poor ...
