| use | used as an intermediate in organic synthesis because this product is soluble in organic solvents, stable to heat and difficult to hydrolyze, it can be used as a resin crosslinking agent; curing agent for acrylic adhesive and curing agent for epoxy resin adhesive; catalyst for olefin polymerization. Catalyst. Crosslinking agent. Aluminum triacetylacetonate is mainly used as a hardening accelerator for epoxy resin. Crosslinking agent for phenol, silicone and acrylic resin. Improve the performance of polymer materials such as inks, coatings, glues, and resins through chemical chelation. Usage: It is used in solvent-based acrylic acid, epoxy, polyester, polyurethane pressure-sensitive adhesive for curing and crosslinking. It does not contain-OH,-COOH,-NH2, etc. It must be pretreated. The addition amount is 1.5-2‰ (the specific amount should be determined after the experiment). After the product synthesis is completed, the diluted aluminum acetylacetonate can be added at the temperature below 70 ℃ and stirred for a few minutes. |
| production method | 1. dissolve 6g(0.06mol) of newly distilled acetylacetone in 40mL of water, stir and drop 6mol/L ammonia water until acetylacetone is dissolved. Dissolve 6g(0.0093mol) aluminum sulfate [Al2(SO4) 3.17H2O] in 60mL of water, and add this solution to acetylacetonate ammonia solution to generate precipitation. The pH of the control solution in the reaction is neutral. Filtering, washing, natural drying. Dissolve the crude product with a small amount of benzene, filter, and slowly add petroleum ether to the filtrate to make it precipitate. Filtration, washing with petroleum ether, natural drying, 4.2g product, 81% yield. If necessary, it can be purified by sublimation. 2. Aluminum acetylacetonate prepared from the reaction of commercially available anhydrous AlCl3 and acetylacetone in chloroform solution contains iron that is difficult to remove. The commonly used method is to use aluminum hydroxide, aluminum acetylacetonate coated from analytically pure aluminum hydroxide with very little iron content, and recrystallize multiple times in petroleum ether to obtain pure aluminum acetylacetonate. |
