| titleOfInvention | A kind of preparation method of long-carbon chain semi-aromatic nylon salt |
| abstract | The invention discloses a kind of preparation method of Long carbon chain semi-aromatic nylon salt, belong to synthesis of polymer material technical field.It is characterized in that: Long carbon chain aliphatic diamine and aromatic acid or aromatic diamine and Long carbon chain aliphatic dibasic acid are added to the water according to the mol ratio of 1:1 by (1), and stir in autoclave, reactant massfraction is 20% ~ 80%; (2) under protection of inert gas, be heated to 100 DEG C ~ 200 DEG C, keep still internal pressure to be 0.2MPa ~ 2MPa, then add appropriate corresponding diamine or diprotic acid, the pH value of adjustment solution, when the pH value of solution is 7.0 ~ 7.5, is incubated 0 ~ 5 hour, starts cooling; (3) lower the temperature with 5 DEG C ~ 50 DEG C/h, when being down to room temperature, centrifugation obtains Long carbon chain semi-aromatic nylon salt.(4) filtrate after centrifugation is joined in step (1) recycle.Present method can control the mol ratio of diprotic acid and diamine exactly, and the semi-aromatic nylon purity salt of preparation is high; And be that medium prepares long-carbon chain semi-aromatic nylon salt with water, simple to operate, raw material reaction is abundant, and salify efficiency is high, and environmental protection is with low cost. |
