Preparation of rhodamine dyes in granule form by direct cooling |
| abstract |
Salts of esterified rhodamine dyes are prepared in granular form by precipitating the rhodamine dyes with sodium chloride from an aqueous medium containing a water-miscible solvent by adding the sodium chloride at 80°-100° C., which precipitates the dyes in liquid form from the aqueous medium, then stirring the liquid dyes to convert them into a droplet form and then chilling the droplets by direct cooling to below 65° C. |
