Abstract:The catalytic activities of acid catalysts for the acetylation of triethyl citrate with acetic anhydride in the preparation of acetyl triethyl citrate were evaluated. Microporous zeolites such as HZSM-5 and HY zeolites catalysts were introduced as heterogeneous acid catalysts. HZSM-5 zeolite catalysts showed a high conversion of triethyl citrate and excellent selectivity of acetyl triethyl citrate. The catalytic activities of HZSM-5 zeolites were superior to those of the HY zeolites. In particular, the selectivity of acetyl triethyl citrate on HZSM-5 zeolites exceeded 95%. The moderate acid strength of HZSM-5 (Si/Al = 75) zeolite led to the highest catalytic activities among the HZSM-5 zeolite catalysts, which have various acid strengths.

“…When the value of HRR reached the peak, it also indicated that the sample released more flammable gas at this time. In order to further study the thermal stability of the TPU composite, a thermal re‐decomposition test was performed 10,17,29 . Figures 12 and 13 show the TG and DTG curves, and the detailed data are given in Table 3.…”

To improve the flame retardant of thermoplastic polyurethane elastomer (TPU) is a very important issue in fire hazard fields. In this article, the structure of copper (II) chelate salicylaldehyde (CuSA) was characterized by X‐ray diffraction (XRD), Fourier transform infrared (FTIR), and scanning electron microscopy (SEM). The influence of CuSA on the fire safety performances of TPU/APP composites was intensively investigated using cone calorimeter test (CCT), smoke density test (SDT), micro‐scale combustion calorimetry (MCC), thermogravimetric‐Fourier transform infrared spectrum (TG‐FTIR), and other testing methods. The CCT test results showed that the peak heat release rate (pHRR) value of CuSA2 sample was 128.1 kW/m2, which was much lower than that of TPU‐APP sample with the pHRR value of 161.9 kW/m2. The SDT test results showed that the luminous flux of CuSA4 is much higher than that of TPU‐APP sample. Therefore, an appropriate amount of CuSA had obvious improvement of fire safety performances in TPU composites. This work provides a new idea for the design and manufacture of fire safety materials.

“…Therefore, a binary flame retardant consisting of sugar‐ coated haw‐like ZHS‐TNT was synthesized in order to improve the flame retardancy and smoke suppression of flexible PVC. [ 60 ] The LOI values and cone calorimetry data are shown in Figure 17. The LOI value of PVC/ZHS‐TNT increased with filler content and reached 29.6% when the content of the filler was 2.5 wt%, higher than that of PVC/TNT, PVC/ZHS and PVC/ZHS+TNT.…”

An Overview of the Flame Retardants for Poly(vinyl chloride): Recent States and Perspective^†

As a versatile star product, poly(vinyl chloride) (PVC) has kept active in our daily life all through since it was invented. However, the severe fire hazard and heavy smoke produced during combustion, particularly the extensively used flexible PVC products, have been puzzling manufacturers and researchers for ages. Over the last decade, multifarious flame retardants and smoke suppressants were developed for PVC materials. In this review, combined literature with the results based on the research from our group, recent emerged flame retardants and smoke suppressants for PVC are introduced. Meanwhile, the flame retardant mechanisms and experimental analysis results are described to understand the relationship between characters of flame retardants (including chemical compositions, structures or morphologies) and fire performance of the composites. The potential substitutes for traditional harmful flame retardant antimony trioxide are discussed aiming to the emphasis on increasing prominent environmental concerns. In particular, one section is dedicated to new approaches for the preparation of novel environmentally friendly and high-efficiency flame retardants. It is hoped that this review will not only summarize the new emerged flame retardants and smoke suppressants for PVC, but also provide the new trend to prompt sequent exploration in both academic research and industrial application.
