| titleOfInvention | A kind of method for improving tebuthiuron crystal mobility |
| abstract | The invention belongs to pesticide field more particularly to a kind of methods for improving tebuthiuron crystal mobility, it is characterised in that include the following steps：Tebuthiuron and organic solvent are mixed to form suspension, suspension then is warming up to tebuthiuron is completely dissolved, and obtains tebuthiuron solution；The tebuthiuron solution is carried out to the decrease temperature crystalline of first stage, tebuthiuron solution is cooled to 25 ~ 30 DEG C, after being down to assigned temperature with 12 ~ 20 DEG C/h of speed, stands 5 ~ 60min of heat preservation；The tebuthiuron solution to cool down through the first stage is carried out to the decrease temperature crystalline of second stage, tebuthiuron solution is cooled to 15 ~ 10 DEG C with 25 ~ 30 DEG C/h of speed, after being down to assigned temperature, tebuthiuron crystal is obtained by filtration after standing 0.5 ~ 6h of heat preservation, mother liquor continues to apply mechanically；The granularity of the tebuthiuron crystal is D90:280 ~ 350 microns.The beneficial effects of the present invention are the tebuthiuron crystal obtained by the method for the present invention, granularity D90:280 ~ 350 microns, there is good crystal mobility so that tebuthiuron product has good anticaking capacity. |
