Flammability and Explosibility
Not classified
Purification Methods
Dissolve the dye in EtOH (1.16g in 30mL), filter and add aqueous NH3 till neutral (colourless) and precipitate it by adding H2O giving 0.8g, m 247o(dec, sintering at 230o). Dissolve it in EtOH, neutralise with NH3 till colourless, add 0.1g of charcoal, filter, and repeat, then add H2O (100mL) to precipitate the colourless carbinol (pseudo-base) and dry it in vacuo, m 257o(dec, also 205o, sintering at 232o). [Weissberger & Theile J Chem Soc 148 1934.] The carbinol is slightly soluble in H2O but is soluble in acids (e.g. HCl to give the coloured chloride [569-61-9]) and EtOH [pK: Goldacre & Phillips J Chem Soc 172 1949]. The perchlorate (dark red with a green shine) has m 300o and explodes at 317o [Dilthey & Diaklage J Prakt Chem [2] 129 1931]. [Beilstein 13 IV 2283.]
