| 应用领域 | Uses: Rhodamine dyes (aminoxanthenes) are xanthene dyes that are very important commercially. They are brilliant、blue-red、fluorescent dyes used as colorants in inks、paper、and plastics. Sulfonated derivatives are used as wool and polyamide dyes. Red fluorescent pigments are produced from Rhodamine dyes、and some of these are used as laser dyes.[Ullmann]、Pulp and Paper Processing [Category: Industry]、Painting (Pigments、Binders、and Biocides) [Category: Paint]、Rhodamine WT、a fluorescent、xanthene dye、has long been used as a hydrologic tracer in surface water systems.、Rhodamine dyes (aminoxanthenes) are a very important class of xanthene dyes and are of considerable commercial importance. They are intensely brilliant、fluorescent dyes with very high molar extinctions and quantum yields and are used for coloring inks、and plastics. Their sulfonated derivatives are used to dye wool and polyamides. Rhodamine dyes are also one of the starting materials for the production of red fluorescent pigments、some of them are employed as laser dyes.、Rhodamine dyes、Methods of Manufacturing: The most important rhodamine dyes are synthesized by reacting 3-dialkylaminophenols with phthalic anhydride. The carboxyl group of the product may then be esterified.、General Manufacturing Information: Rhodamine derivatives have been reported for use in photodynamic diagnosis and treatment |
