| titleOfInvention | Fusion-crystallization refines the method and its fusion-crystallization device of the 5-chloromethyl thiazole of 2 chlorine 5 |
| abstract | The invention discloses the method and its fusion-crystallization device that a kind of fusion-crystallization refines the 5-chloromethyl thiazole of 2 chlorine 5, it is related to the 5-chloromethyl thiazole purification technique field of 2 chlorine 5.Comprise the following steps：Crystal growth：Cool the temperature to 10~25 DEG C, it is passed through 35~47 DEG C of 2 5-chloromethyl thiazole material liquid of chlorine 5, allow 1.5~2.5h of crystal layer growth, 2.5~5h of crystal layer regrowth is allowed with 2~4 DEG C/h cooling rates again, keeping temperature stands 15~25 minutes, then discharges the uncrystallized remaining 5-chloromethyl thiazole material liquid of 2 chlorine 5；Sweating：Elevated the temperature with 2~4 DEG C/h heating rate, melt crystal layer, 28~30 DEG C of sweating end temp；Discharge sweating；Fusing：Crystal layer is all melted, collects the 5-chloromethyl thiazole of 2 chlorine of high-purity 5.The inventive method technique is simple, and running cost is low, and three wastes produce, and product purity is high, high income；The apparatus structure is simple, and cost is low. |
