| titleOfInvention | Preparation method for hexamethylene diisocyanate biruet |
| abstract | The invention discloses a preparation method for hexamethylene diisocyanate biruet, according to the method, azeotrope formed by a mixture of deionized water and a polar aprotic solvent is heated into a temperature of 30-100 DEG C; hexamethylene diisocyanate monomer is put into a reactor, and the temperature is maintained at 90-140 DEG C; the azeotrope is dropped into the reactor at a dropping speed of 0.05-0.20g/min; the temperature is increased into 110-150 DEG C in a mixing state, and the azeotrope is reacted for 1-4h; the temperature is reduced below 40 DEG C for cooling and discharging; and the discharging material enters into a separation device for separating a solvent and hexamethylene diisocyanate biruet ingredient, and a solid content of hexamethylene diisocyanate biruet ingredient is adjusted between 50 percent and 90 percent by a diluent. According to the preparation method, new solvent is not needed for addition, production formula and operation process are not required to be changed, only the monomer of isocyanate and water are added to realize continuous production, and the real clean production is realized via zero-release. |
