| titleOfInvention | Synthesis method and application of a kind of polyester flame retardant finishing agent |
| abstract | The present application discloses a synthesis method and application of a flame retardant finishing agent for polyester. The synthesis method comprises the following steps: dissolving phosphorus oxychloride in n-hexane to prepare a n-hexane solution of phosphorus oxychloride, placing the n-hexane solution of phosphorus oxychloride in a flask equipped with a condenser, heating the The amine solution produces methylamine vapor, and the methylamine vapor is passed into the n-hexane solution of phosphorus oxychloride until the solution is neutral to obtain a crude product of phosphoric acid triformamide; remove the methylamine device, heat the reaction solution with a constant temperature water bath, and recover n-hexane Solvent, then add distilled water to dissolve phosphoric acid triformamide, and then cool and crystallize to obtain finishing agent phosphoric acid triformamide. The hot aqueous solution of triformamide phosphate prepared by the invention is used for durable finishing of polyester fabrics, and polyester fabrics with durable flame retardancy are prepared. |
