Dioctylphthalate

Air filter A device that removes particulate matter from a gas flowing through it. These are classified as Absolute A high-efficiency particulate air filter that is at least 99.79% efficient in the removal of thermally generated mOnodisperse dioctylphthalate smoke particles with a diameter of 0.3 pm, also known as a HEPA filter. 

Cold-generated DOP A cold-generated aerosol dioctylphthalate (DOP) test, used to measure the efficiencies of high-efficiency filters. A hot DOP test may also be used.

The flexibility of some plastics can be improved by the addition of small molecules called plasticizers. For example, pure PVC turns brittle and cracks too easily to make useful flexible plastic products. With an added plasticizer, however, PVC can be used to make seat covers for automobiles, raincoats, garden hoses, and other flexible plastic objects. Plasticizers must be liquids that mix readily with the pol Tner. In addition, they must have low volatility so that they do not escape rapidly from the plastic. Dioctylphthalate is a liquid plasticizer that is formed by condensing two alcohol molecules with one molecule of phthalic acid, as illustrated in Figure 13-10.

SEC has sometimes been used with off-line IR spectroscopy for the detection of polymer additives, such as dioctylphthalate, as well as on-line [39]. Dissolutions of PVC/DEHP and of PC/pentaerythritoltetrastearate (release agent) were analysed by SEC-FTIR using the thermospray/moving belt/DRIFT interface [40]. The detection limits of the method were in the 100 ng range, depending on the IR sensitivity and volatility of the solutes. This is not extremely sensitive. 

Abbreviation for dioctylphthalate, a plasticiser for natural and synthetic rubbers. 

The current annual production of di-ra-octylphthalate is difficult to estimate because of confusion in nomenclature regarding the octylphthalate isomers and reported data describing only the entire group of dioctyl orthophthalates. A total of 122,384 metric tons of total dioctylphthalates were produced in 1992 (USITC 1994). The amount of di-w-octylphthalate included in this group was not reported because of the possible revelation of confidential business information. 

Flexible PVC resins and other dioctylphthalate-containing plastics and resins are used in a variety of industrial and domestic products plastisols for carpetback coating (EPA 1987b), film, wire, cables, and adhesives (HSDB 1995). Additional end-use products are automobile and furniture upholstery, wall coverings, window shades, garden hoses, shower curtains, tablecloths, rainwear, shoes, dolls, and toys (Mannsville Chemical Products Corporation 1989).
