The commonly used plasticizers accounted for the largest proportion of phthalic acid esters, and their yield accounted for about 80% of the total plasticizer production. In this paper, some

Sep 1, 2009Phthalic acid esters (PAEs), commonly known as phthalates, are a group of organic and synthetic chemical compounds with a wide spectrum of industrial applications. They are dialkyl or alkyl aryl esters of 1,2-benzenedicarboxylic acid, called phthalic acid, produced by the chemical reaction of phthalic anhydride with an alcohol.

Which phthalate molecule is used as a plasticizer?
Higher phthalate molecules, such as di (2-ethylhexyl) phthalate, diisononyl phthalate, and butyl benzyl phthalate, have a wide range of applications as plasticizers in the polymer industry to improve flexibility, workability, and general handling properties, and about 80% of PAEs are used for this purpose [20, 25].
Where are phthalic acid esters located?
Phthalic acid esters (PAEs) (otherwise known as phthalates, phthalate esters, or dialkyl phthalate esters) are composed of one benzene ring and two ester groups (Sablayrolles et al., 2005) which are located in the ortho position (F. Chen et al., 2021; Erythropel et al., 2014; Przybylińska & Wyszkowski, 2016; Xiong & Pei, 2021).
Which plasticizer has the highest concentration of phthalate?
We detected eight ortho-phthalates and three alternatives ( (1,2-cyclohexane dicarboxylic acid diisononyl ester (DINCH), diethylhexyl terephthalate (DEHT), and diisobutyl adipate (DIBA). Diethylhexyl phthalate (DEHP) was measured in all 71 products. DEHT had the highest concentration of any plasticizer (>10,000 ng/g in three oils).
Are phthalate acid esters a good treatment for microbial degradation?
Phthalate acid esters (PAEs), a group of xenobiotic compounds used extensively as plasticizers, have attracted increasing concern for adverse effects to human health and the environment. Microbial degradation relying on PAE hydrolases is a promising treatment. However, only a limited number of PAE hydrolases were characterized to date.
Which phthalate is found in plastic packaging?
We analyzed plastic packaging composition using FTIR spectroscopy. We detected eight ortho-phthalates and three alternatives ( (1,2-cyclohexane dicarboxylic acid diisononyl ester (DINCH), diethylhexyl terephthalate (DEHT), and diisobutyl adipate (DIBA). Diethylhexyl phthalate (DEHP) was measured in all 71 products.
Which enzyme converts di-alkyl phthalate into phthalic acid?
In the first reaction, the enzyme di-alkyl phthalate hydrolase converts the di-alkyl phthalates to their monoalkyl ester forms (hydrolyzation step I) which is then converted into phthalic acid (PA) by the activity of the enzyme monoalkyl phthalate hydrolase (hydrolyzation step II) (Fan et al., 2018; Tang et al., 2016; Wu et al., 2010a).
