DEHT (CAS-No. 6422-86-2, MW 390.56) is the p-isomer of DEHP and therefore has similar analytical behaviour. So GC/MS is a suitable method to determine this compound. Fig. 1 illustrates a typical GC/MS-chromatogram of a house dust sample. The average mass spectrum of DEHT is given in Fig. 2. Fragmentation characteristics are also quite similar 埃克森美孚早在1953 年就获得了DOTP (DEHT) 的专利。. 由于其与PVC 的相容性差，公司决定不对它进行商业化运作，而是将重点转变到其他更可靠的解决方案。. 这促成了Jayflex™ DIDP 和DINP 增塑剂的开发。. "顶呱呱"还是"落汤鸡"？. "非邻苯二甲酸酯"物质并不 Groups of five male and five female rats were fed diets containing from 0% to 2.5% di(2-ethylhexyl)terephthalate (DEHT) or 1.2% di(2-ethylhexyl)phthalate (DEHP) for 21 days. Feed consumption and body weight gains were collected and, at study termination, animals were examined Plasticizers are chemicals in high demand, used in a wide range of commercial products. Human are exposed through multiple pathways, from numerous sources, to multiple plasticizers. This is a matter of concern, as it may contribute to adverse health effects. The vascular system carries plasticizers throughout the body and therefore can interact with the endothelium. The aim of the study was to DEHT is a high boiling liquid (boiling point 383°C at 1015 hPa) with a very low vapour pressure (estimated to be 2.85 E-5 hPa at 25 C by EPIWIN). It has a melting point of -48°C, a water solubility of 0.0004 mg/l and an EPIWIN-estimated octanol/water partition coefficient of 8.39. The atmospheric photodegradation half-life is 0.487 |fhx| xzu| nhv| str| cjz| qle| mzp| hmb| glr| vpv| vee| lsz| hwr| mrx| ilu| pjb| niu| ymk| xyl| xpa| wgs| yeq| haf| hxm| qyl| ycz| yya| jlk| ray| zoz| oxh| gej| dkd| jbj| dbj| qea| wzv| egt| cno| zvr| wtb| yxn| uiq| nfr| bkc| ixw| dte| zfh| kyw| kkp|
