Process for the production of rhodamine dyes in the shape of granulates |
| abstract |
Process for the preparation of salts of esterified rhodamine dyes in granular form by precipitating the rhodamine dyes from an aqueous medium which contains a water-miscible solvent by means of sodium chloride, the addition of sodium chloride being carried out at a temperature of 80 to 100 ° C and the Separates dyes in the liquid state from the aqueous medium, then brings them into droplet form by stirring and then quenched them by direct cooling to a temperature below 65 ° C. |
