| Introduction | Basic Green 1 is also called brilliant green, brilliant green belongs to basic triphenylmethane dyes, in aquaculture is often used as fungicides and antiparasitic drugs, due to triphenylmethane has mutagenic, teratogenic and carcinogenic effects, Europe and the United States and China has been strictly prohibited the use of triphenylmethane dyes in aquaculture, due to the use of brilliant green in the aquaculture process, the water and soil in the pond are polluted, and the residues are easy to form in the fish in the subsequent breeding process, therefore, effective monitoring of pond water and soil is needed for fish culture. |
| Application | Basic Green 1 can be used for dyeing hemp, silk, acrylic fabric and grass products, it is also used for dyeing paper and making lakes. |
| Use | alkaline brilliant green is used for dyeing acrylic fibers at high temperature (120 ℃) without changing color. Can also be dyed silk, wool, Tannin medium dyeing cotton fiber, light fastness are 1-2. When dyeing acrylic fiber, in addition to a separate dye brilliant green, but also with cationic blue dye fruit Green. Also used for leather, paper, hemp, bamboo, wood, grass products coloring. for cotton, silk, acrylic and hemp dyeing. It is also used for dyeing paper and making lakes. It can be used as a disinfectant for external use in medicine. mainly used for cotton, silk, acrylic fiber, hemp dyeing, can also be used for paper dyeing and manufacturing Lakes 1, acid-base indicator, pH0.0 (yellow) ~ 2.6 (green). Preparation of bacterial culture medium, used to identify Escherichia coli and other lactic acid fermentation bacteria, culture and isolation of Salmonella Typhi in feces. 2, for ion-pair chromatography determination of fatty acids, sulfite determination. |
| production method | condensation of N,N-diethylaniline with benzaldehyde in the presence of urea, then lead dioxide and hydrochloric acid oxidation, and then with sodium sulfate to remove lead, neutralized with sodium carbonate, sulfuric acid dissolution, crystallization, filtration and drying to get the finished product. Raw material consumption (kg/t)N,N-diethylaniline 515 benzaldehyde 325 lead dioxide 745 with benzaldehyde and N,N-diethylaniline as raw materials, first condensation, then oxidation, the salt-forming product was obtained.. |
