摘要

摘要采用氧化铋、新癸酸和乙酸酐共反应的方法合成了新癸酸铋(Bi(Ne)3),并用傅里叶变换红外光谱(FTIR)和元素分析(EA)对其进行了表征。通过热老化试验、刚果红试验、电导率测定和热重分析,分别评价了Bi(Ne)3作为热稳定剂对聚氯乙烯(PVC)的影响。结果表明,Bi(Ne)3对PVC具有良好的初始色和长期稳定性。Bi(Ne)3通过吸附氯化氢(HCl)和取代PVC分子链上的活性氯原子来提高PVC的稳定效率。图形抽象

Synthesis of Bismuth(III)Neodecanoate and Its Application to Poly(Vinyl Chloride) as a Thermal Stabilizer
ABSTRACT The bismuth(III)neodecanoate (Bi(Ne)3) was synthesized via the method of co-reaction of bismuth oxide, neodecanoic acid, and acetic anhydride and then characterized by Fourier transform infrared spectroscopy (FTIR) and elemental analysis (EA). The effect of Bi(Ne)3 as a thermal stabilizer on poly(vinyl chloride) (PVC) was assessed by thermal aging test, Congo red test, conductivity measurement, and thermogravimetric analysis, respectively. The results showed that Bi(Ne)3 significantly provided PVC with a good initial color and long-term stability. Bi(Ne)3 played a role in improving the stabilizing efficiency of PVC through absorbing hydrogen chloride (HCl) and displacing labile chlorine atoms in PVC molecular chains. GRAPHICAL ABSTRACT
