Abstract

In the research, a bio‐based through epoxidizing, plasticizer was created non‐toxic custard apple seed oil (CASO) using peroxy acid generated in situ and investigates the application of a bio‐based plasticizer in the compounding of polyvinyl chloride as epoxidized custard apple seed oil (ECASO) (PVC). The ECASO was synthesized through an epoxidation reaction and characterized using Fourier‐transform infrared spectroscopy and analytical parameters such as epoxy value, and oxirane conversion. To create plasticized PVC, the PVC was mixed with different ratios of ECASO and dioctyl phthalate (DOP) using a two‐roll mill and prepared PVC sheet by compression molding. The ECASO plasticizer completely fuses with PVC and plasticized PVC sheets are made. Glass transition temperature, tensile strength, percent elongation, solvent resistance, differential scanning calorimetry (DSC), and thermal gravimetric analysis were among the mechanical and thermal characteristics of PVC sheets that were assessed. This result shows the plasticization efficiency of ECASO and DOP combined was similar to that of DOP alone, even with the same plasticizer loading. Moreover, when used in combination with DOP, ECASO was found to be a more efficient plasticizer. As a result, ECASO can be used as a biobased substitute for DOP, replacing up to 60% of the ECASO plasticizer loading.

利用吉士苹果籽油合成用于聚氯乙烯的生物基增塑剂

这项研究利用原位生成的过氧酸，通过环氧化作用制造出无毒的吉士苹果籽油（CASO）生物基增塑剂，并研究了环氧化吉士苹果籽油（ECASO）（聚氯乙烯）这种生物基增塑剂在聚氯乙烯复合物中的应用。环氧化吉士苹果籽油是通过环氧化反应合成的，并利用傅立叶变换红外光谱和环氧值、环氧乙烷转化率等分析参数对其进行了表征。为了制备增塑聚氯乙烯，使用双辊研磨机将聚氯乙烯与不同比例的 ECASO 和邻苯二甲酸二辛酯（DOP）混合，然后通过压缩成型制备聚氯乙烯板材。ECASO 增塑剂与聚氯乙烯完全融合，制成增塑聚氯乙烯板。评估了 PVC 片材的玻璃化温度、拉伸强度、百分比伸长率、耐溶剂性、差示扫描量热法（DSC）和热重分析等机械和热特性。结果表明，即使增塑剂含量相同，ECASO 和 DOP 组合的增塑效率与 DOP 单独使用的增塑效率相似。此外，ECASO 与 DOP 合用时，塑化效率更高。因此，ECASO 可用作 DOP 的生物基替代品，取代高达 60% 的 ECASO 增塑剂用量。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
