| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Use | used as dye intermediate dye cationic blue X-GRRL, an intermediate of cationic pink FG. |
| production method | prepared by hydroxylation of N-methylaniline and ethylene oxide. 105kg of N-methylaniline was added to the reaction pot, heated to 130 ° C., and the air was replaced with nitrogen. At 150-152 °c, about 0.3MPa or less, 50kg of ethylene oxide was fed in batches. After the addition, the mixture was incubated at 150-155 °c for 3H to give 150-155kg N-Hydroxyethyl-N-methylaniline. |
