“…VDC could be copolymerized with other polymer monomers to form PVDC resin, [1] which was widely used in military supplies, pharmaceuticals, and food packaging due to its excellent performance in isolating oxygen and water vapor. [2] VDC could also be used as a raw material to generate PVDF, which was an important adhesive for lithium-ion batteries. [3] In response to the rapid growth in demand for VDC, it was necessary to study the process route for efficient, energy-saving, and environmentally friendly production of VDC.…”

PVDC played an irreplaceable role in the field of sealed packaging, and its polymer monomer, VDC, was in short supply. At present, the saponification of 1,1,2‐TCE and sodium hydroxide was used to generate VDC in industry, which was a process with great environmental pollution. Catalytic dehydrochlorination of 1,1,2‐TCE to produce VDC was a green process route, but the selection of catalysts had always been controversial. This study aimed to screen catalysts suitable for industrial applications. The cesium based catalysts with good catalytic performance were systematically characterized and evaluated, and the overall reaction process was calculated using DFT calculation. The experimental results indicated that the cesium chloride catalyst with a 3 % molar fraction had the best catalytic performance, achieving 55.27 % conversion of 1,1,2‐TCE and 76.85 % selectivity for VDC, respectively. The reaction paths and transition state of several catalysts were calculated by DFT method. It was revealed that the activation energy required for the reaction of CsCl catalyst was the lowest, at 130.61 kcal/mol, and the energy of the product VDC was the lowest, at −63.25 kcal/mol, making it the most stable. The calculation results were consistent with the experimental data, indicating that cesium chloride catalyst had the best reaction performance. Therefore, the subsequent research could focus on the method of improving the supported dispersity of cesium chloride catalyst and the development of core‐shell catalyst to lay the foundation for further industrialization.

The optimization of the process conditions for fire retardant ultra-low density fiberboards (ULDFs) was investigated using response surface methodology (RSM).Three parameters, namely those of Borax-Zinc-Silicate-Aluminum (B-Zn-Si-Al), chlorinated paraffin (CP), and chloride-vinyl chloride emulsions (PVDC) were chosen as variables. The considerably high R 2 value (99.98%) indicated the statistical significance of the model. The optimal process conditions for the limiting oxygen index (LOI) were determined by analyzing the response surface's three-dimensional surface plot and contour plot, and by solving the regression model equation with Design Expert software. The Box-Behnken design (BBD) was used to optimize the process conditions, which showed that the most favorable dosages of B-Zn-Si-Al, CP, and PVDC were 800 mL, 46.47 mL, and 35.64 g, respectively. Under the optimized conditions, the maximum LOI was 48.4.
