degradation of dimethyl phthalate using persulfate activated,dimethyl phthalate ester (dmpe) is one of the phthalates widely used for producing polyvenil chloride resin, adhesive material and colour. they are commenly used in home furnishings, aeterial structures, food pockets and polyvinylchloride (pvc) resins [3, 4]. phthalate esters are classified as recalcitrant, hazardous and emeging contaminants [5.
introduction. dimethyl phthalate (dmp) is commonly used as a plasticizer to impart flexibility to rigid polyvinylchloride (pvc) resins (boonnorat et al. 2014).as one of the phthalate esters (paes), dmp is the most extensively used compound for manufacturing various consumer products, and the consumption of it is increasing continually (fang et al. 2009; prasad and suresh, 2015) every year.

dimethyl phthalate plasticizer 131-11-3 chemical,dimethyl phthalate (dmp) is a short-chained ester known as a phthalate acid ester. it is majorly used as a plasticizer for the production of polyvinyl chloride (pvc) and in the coating of cellulose films.
- 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).
- 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 DMP purified?
- As with other phthalates, the unreacted alcohols are recovered and reused, and the DMP mixture is purified byvacuum distillation or activated charcoal. The purity of DMP can achieve 99% or greater using current manufacturing processes (BASF, 2008).
- Do polyvinyl chloride microplastics release phthalate and non-phthalate plasticizers into sediment?
- This study investigated the leaching of phthalate and non-phthalate plasticizers from polyvinyl chloride microplastics (MPs) into sediment and their degradation over a 30-d period via abiotic and biotic processes. The results showed that 3579% of plasticizers were released into the sediment from the MPs and > 99.9% degradation was achieved.
- Are DEHT and DINP phthalate plasticizers present in PVC chromatograms?
- Note that we monitored the DEHT (non-phthalate) and DINP (phthalate) plasticizers in both MPs; however, two additional peaks in the GC-MS chromatogram from each PVC sample remained unknown and were not considered in this study.
- 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.
