Oxidative degradation/mineralization of dimethyl phthalate (DMP)
A novel ferrate(VI)/titanium dioxide/ultraviolet [Fe(VI)/TiO2/UV] system was successfully established for the photocatalytic oxidation of dimethyl phthalate (DMP). This system demonstrated a higher removal efficiency of DMP (95.2%) than the conventional TiO2/UV and Fe(VI) alone systems (51.8% and 23.5%, respectively) and produced obvious synergistic effects. Response surface methodology (RSM
Process optimization and kinetic study of biodegradation of dimethyl
Dimethyl phthalate (DMP) is the low molecular weight phthalate ester used in plastic products to increase their flexibility, pellucidity, resilience, and longevity 3,4.
Ecotoxicological and genotoxic effects of dimethyl phthalate (DMP) on
Molecules with one, two or three carbon-atoms in their hydrocarbon chain, namely dimethyl phthalate (DMP), diethyl phthalate (DEP) and diallyl phthalate (DAP), are generally used in cosmetics, personal care products, solvents and adhesives (Schettler, 2006).
Anthropogenic Occurrence of Phthalate Esters in Beach
Five beaches in Ulsan and Busan, South Korea, were investigated for the anthropogenic occurrence of four PEs (dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate (DnBP), and
Comparative Analysis of Neurotoxicity of Six Phthalates in
The effects and underlying mechanisms of phthalates on neurotoxicity remain unclear as compared with the potentials of these substances as endocrine disruptors. The locomotor activities of zebrafish embryos were investigated upon exposure to six phthalates: dimethyl phthalate (DMP), diethyl phthalat
- Is DMP a phthalate?
- Levels of DMP, and otherphthalates including diethyl phthalate, DBP, and DEHP, in semen of a group of proven fertile men (i.e., who had offspring within 1 year of the study) were lower than levels in a group of infertile men (who had regular unprotected intercourse within 1 year without their partners achieving pregnancy) (Pant et al., 2008).
- How many phthalates are there in Korea?
- In Korea, three phthalates such as DMP, BBP, and DnOP have been measured recently in four major rivers ( Cho et al., 2014 ). However, there is still insufficient data on phthalate levels in the environment in Korea. Up to now, no comprehensive measurements of fourteen PEs in various environmental media have been reported in Korea.
- Is DMP a health hazard?
- Results from studies of animals exposed repeatedly to DMP (mostly by the oral route) provide evidence, however, thatDMP has less potential to induce health hazards than some other phthalates, such as DEHP and butylbenzyl phthalate.
- How is phthalic anhydride (DMP) made?
- In general, DMP is manufactured commercially in a closed system bycatalytically esterifying phthalic anhydride with methanol (HSDB 2009). As with other phthalates, the unreacted alcohols are recovered and reused, and the DMP mixture is purified by vacuum distillation or activated charcoal.
- Is DMP a benzene-dicarboxylic acid ring?
- DMP is comprised of a pair of 1-carbon esters linked to a benzene-dicarboxylic acid ring. The branched ester side chains are in an ortho configuration, in contrast to those found in isophthalates (meta) or terephthalates (para). DMP is currently considered to belong to the Low Molecular Weight Phthalate Esters (LMWPE) group.
- Is dimethyl phthalate a potent male rat reproductive tract toxicant?
- The results provide supportive evidence that gestational exposure to dimethyl phthalate isnot a potent male rat reproductive tract toxicant like other phthalate esters, such as DBP and DEHP.
