| titleOfInvention | Method for synthesizing semi-aromatic nylon salt by using mixed solvent |
| abstract | The invention discloses a method for synthesizing a semi-aromatic nylon salt by using a mixed solvent composed of water and an organic solvent. The method comprises the steps: mixing aliphatic diamine and water, pulping, and heating the aliphatic diamine solution to 60-98 DEG C, and remaining the aliphatic diamine solution for later use; mixing aliphatic diacid and an organic solution, heating the aliphatic diacid solution to 60-120 DEG C until the aliphatic diacid is completely dissolved, and remaining the aliphatic diacid solution for later use; slowly adding the aliphatic diacid solution into the aliphatic diamine solution, and carrying out neutral reaction at the temperature of 60-98 DEG C; and regulating the pH value to 7.0-7.5, then, cooling, centrifugally separating, washing by using deionized water, and drying to obtain the semi-aromatic nylon salt. The semi-aromatic nylon salt prepared by using the method disclosed by the invention is high in purity, favorable in particle crystal form, easy to separate and purify, low in consumption of organic solvent, mild in reaction condition and low in energy consumption. The organic solvent used in the method can be recycled. |
