Application | used as dye and organic pigment intermediate used as an important dye intermediate for the dispersion of yellow brown 3GL, decomposition of yellow brown 2RFL, disperse Brown 3R, disperse Brown 5R. In the late 50 s, it began to be marketed as a fungicide. As a broad-spectrum agricultural fungicide, it can be used to control Sclerotinia sclerotiorum disease of sweet potato, kenaf, cucumber, lettuce, cotton, tobacco, strawberry, potato, and soft rot of sweet potato, cotton and peach; potato and tomato late blight; Apricot, almond and Apple blight; Wheat smut; Broad bean rot. Chlornitramine can be used in combination with most insecticides, fungicides, Bordeaux mixture, lime and sulfur. |
production methods | There are mainly the following methods: P-nitroaniline in hydrochloric acid-glacial acetic acid chlorination; 2-sulfonyl-4-nitroaniline chlorination; P-nitroaniline chlorination in dilute hydrochloric acid and sodium hypochlorite; P-nitroaniline reaction in hydrogen peroxide and hydrochloric acid; P-nitroaniline sulfonation before chlorination in concentrated sulfuric acid; P-nitroaniline was reacted with sodium chlorate in concentrated hydrochloric acid. |
