简介

Rhodamine 6G is a highly fluorescent rhodamine family dye. It is often used as a tracer dye within water to determine the rate and direction of flow and transport. Rhodamine dyes fluoresce and can thus be detected easily and inexpensively with instruments called fluorometers. Rhodamine dyes are used extensively in biotechnology applications such as fluorescence microscopy, flow cytometry, fluorescence correlation spectroscopy and ELISA.
Rhodamine 6G chloride powder mixed with methanol, emitting yellow light under green laser illumination; Rhodamine 6G-based dye laser. The dye solution is the orange fluid in the tubes; Rhodamine 6G is also used as a laser dye, or gain medium, in dye lasers, and is pumped by the 2nd (532nm) harmonic from an Nd:YAG laser or nitrogen laser. The dye has a remarkably high photostability, high fluorescence quantum yield (0.95), low cost, and its lasing range has close proximity to its absorption maximum (approximately 530nm). The lasing range of the dye is 555 to 585nm with a maximum at 566nm.
Rhodamine 6G usually comes in three different forms. Rhodamine 6G chloride is a bronze/red powder with the chemical formula C27H29ClN2O3. Although highly soluble, this formulation is very corrosive to all metals except stainless steel. Other formulations are less soluble, but also less corrosive. Rhodamine 6G perchlorate (C27H29ClN2O7) comes in the form of red crystals, while rhodamine 6G tetrafluoroborate (C27H29BF4N2O3) appears as maroon crystals.

生产方法及用途

生产方法

1.3-乙氨基对甲苯酚 (p-cresol, 3-ethylamino) 和苯酐为原料,首先将两者缩合,然后再用乙醇进行酯化即得产物
2.以邻甲苯胺用氯乙烷烷基化,磺化,碱熔后与苯酐缩合,用氯乙烷酯化,经后处理得产品。

用途

碱性红 6GDN 适用于染蚕丝以及蚕丝织物的直接印花。一般用于中性、酸性直接染料多色套印中作点缀色彩之用,不印大、中块面花型。用于染羊毛、棉纤维时,色牢度较差。可用于皮革、纸张着色,也用于制备有机颜料。与磷钨钼酸作用生成色淀用于制造高级油墨的颜料,也可用于腈纶、毛、丝的染色
