| titleOfInvention | Tetrachloroethylene solid composite stabilizer and preparation method therefor |
| abstract | The present invention relates to a tetrachloroethylene solid composite stabilizer and a preparation method therefor. The stabilizer comprises the following components in parts by weight: 10-30 parts of an ion exchange resin containing substituted phenol groups, 50-80 parts of a basic anion resin, and 50-100 parts of a desiccant, wherein the ion exchange resin containing substituted phenol groups is a phenolic compound-substituted chloromethylated macroporous styrene-divinylbenzene copolymer and the basic anion resin is an amine compound-substituted chloromethylated macroporous styrene-divinylbenzene copolymer. The ion exchange resin containing substituted phenol groups, the basic anion resin, and the desiccant are proportionally mixed until uniform to prepare the tetrachloroethylene solid composite stabilizer, and same is then packaged with a glass fiber bag and placed in tetrachloroethylene for storage and use. The solid composite stabilizer of the present invention is not miscible with tetrachloroethylene, does not affect the purity, does not produce IR impurities, and has a very good stabilizing effect on tetrachloroethylene, and the stabilizing effect on tetrachloroethylene lasts 18 months or longer. |
