Standard Guide for Purity of Monomeric Plasticizers by Gas
Scope. 1.1 This gas chromatographic guide covers a procedure for extending the range of purity determination of monomeric plasticizers beyond that now determined by other methods. Due to the need to volatilize the plasticizer, only monomeric plasticizers having definitive boiling points and a molecular weight less than 1000 Daltons, such as
Plasticizer - an overview | ScienceDirect Topics
A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer. The amount of plasticizer needed to obtain a certain hardness or elongation is a measure of its efficiency.
Pembuatan dan Karakterisasi Bioplastik Berbahan Dasar
The making of bioplastics is carried out for two variations of mixture, namely cassava starch as the material-based, glycerol + water as plasticizer, acetic acid (vinegar) as a catalyst and the...

Influence of Weather and Purity of Plasticizer on Degradation
1. Introduction. Petroleum-based plastic is tough, light, flexible, versatile, moisture resistant and relatively inexpensive. These qualities have seen both its production and use rise to meet diverse human needs, ranging from packaging to electronic device components [1].
- Are primary plasticizers good for Environmental Protection?
- Currently, the performance of primary plasticizers produced in China cannot fully satisfy the requirements for environmental protection, especially poor cleanliness and high toxicity. DOP and dioctyl adipate (DOA), especially the former, are the plasticizers widely used in PVC-based food wrap and packaging.
- Which plasticizers are environmentally friendly?
- Currently, commercial environmentally friendly plasticizers include aliphatic acid esters, citrates, epoxy, terephthalates, high-carbon phthalate esters, cyclohexane dicarboxylates (or tetrahydrophthalates), polyesters, phenyl polycarboxylates, etc.
- What is the most widely used plasticizer in China?
- DOP is currently the most widely used plasticizer, ~70% of the total consumption of plasticizers. In China, the annual consumption is close to 1 million tons. In recent years, the medicine, food packaging, daily supplies, and toys industries have raised more stringent requirements to plasticizers.
- Why is dehch a good plasticizer?
- DEHCH is an exceptional low-toxicity, environmentally friendly plasticizer. China is the major producer of DOP. Production of DEHCH via hydrogenation of DOP is of important significance to the upgrading of plasticizers in China. High-performance catalyst is a key factor for the hydrogenation of DOP.
- How to develop environmentally friendly plasticizers of independent intellectual property rights?
- In order to develop environmentally friendly plasticizers of independent intellectual property rights, the authors have synthesized DEHCH using HPPA and 2-ethylhexanol as the raw materials with the methanesulfonic acid catalyst, and have determined its molecular structure using GC-MS.
- Are plasticizers toxic?
- For a long time, the dominant plasticizers are phthalates such as DOP, but their toxicity has received increasing attention following their wide use in the food and medicine industry. When the blood stored in PVC bags is transfused into the human body, DOP materials are found in the lung.
