| Пользы | Zinc acetylacetonate can be used as an additive. It is the most commonly used heat stabilizer including halogenated polymers, especially polyvinyl chloride. It is also used as a catalyst. It can also be used as a resin crosslinking agent, resin hardening accelerator, resin, rubber additive, superconductive film, hot wire reflective glass film, transparent conductive film forming agent, etc. It is an environmentally friendly product that replaces lead-containing additives. |
| обзор | zinc acetylacetonate (ZAA), English Zinc(II) acetylacetonate, molecular structure formula C10H14ZnO4, melting point 129-133 ℃, white crystalline powder at room temperature, easily soluble in methanol, characteristic odor, stable properties, easy to react with oxidant. This product is the most commonly used heat stabilizer in the formulation of polyvinyl chloride. It is also used as a heat stabilizer for halogenated polymers such as hard PVC. It has significant synergistic effect with stearoyl benzoyl methane and dibenzoyl methane (β-diketone). In addition, it is also used as a catalyst, resin crosslinking agent, resin hardening accelerator, resin, rubber additive, super conductive film, hot wire reflective glass film, transparent conductive film forming agent, etc., is an environmentally friendly product that replaces lead-containing additives. Industrial use of acetic acid cracking process, acetic acid as raw material, triethyl phosphate as a catalyst, in high temperature vacuum cracking to produce ketone, and then by acetone absorption and conversion to acetylacetone zinc crude, refined by tower fractionation, the cost content is greater than 98%. |
| photocatalytic performance of zinc-doped titanium dioxide nanocrystals synthesized by gas phase flame combustion | zinc-doped titanium dioxide nanocrystals were synthesized by gas phase flame combustion using titanium tetrachloride and zinc acetylacetonate as raw materials. the nanocrystals structure was studied by XRD, XPS and ICP-AES, and the activity of zinc-doped titanium dioxide nanocrystals for catalytic degradation of rhodamine B(Rhodamine B) under ultraviolet irradiation was investigated, the photocatalytic mechanism is discussed. The results show that the doped phase zinc is mainly distributed in the surface phase of titanium dioxide and forms uniformly dispersed ZnO clusters; during the combustion process, zinc doping has little effect on the crystal phase composition and grain size of nano-titanium dioxide. When the doping amount is 0.21%(mol), the sample has the highest photocatalytic activity. The photocatalytic mechanism analysis shows that the different energy band positions of titanium dioxide and ZnO enable the photogenerated carriers to be effectively separated, improved the photocatalytic activity of nano-titanium dioxide.
