Keep away from fire and heat sources. Protect from direct sunlight. Keep container tightly sealed. They should be stored separately from oxidants, acids, acid anhydrides, acid chlorides, and food chemicals, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.\n <\/p>\nSynthesis method<\/h2>\n1. Obtained from chlorination and reduction of p-nitrotoluene. 1. Chlorination Add nitrotoluene to the reaction pot, heat to 75\u00b0C, add anhydrous ferric chloride and iodine, stir for 10-20 minutes, start chlorine flow at 60\u00b0C, and keep the chlorination temperature at 55-70\u00b0C , when the melting point of chloride is >58.5\u00b0C and does not grow within 20 minutes. Catch the air, raise the temperature to 80-90\u00b0C, and keep it for 1.5-2 hours to obtain 2-chloro-4-nitrotoluene with a yield of 98%. 2. Reduction: Add the prepared sodium sulfide solution into the reaction pot, add the above-mentioned 2-chloro-4-nitrotoluene at 70-80\u00b0C, reflux for 4 hours, the temperature is 110\u00b15\u00b0C, the purity of the amine oil is >98.5%, melting point When >19\u00b0C, distill to obtain the finished product with a yield of 90%. If iron powder is used for reduction, the reaction temperature is about 100\u00b0C, and the reactants are extracted with toluene. The yield is about 95%. <\/p>\n2. The preparation method is to add molten 3-chloro-4-methylnitrobenzene and solvent into the autoclave, and then pump a certain amount of catalyst and distilled water into the autoclave under negative pressure. The hydrogenation reaction is catalyzed under a certain temperature and pressure, and then the materials are pumped into the storage tank, left to stand and stratified, and the materials are rectified in the distillation kettle to obtain the solvent and the finished product respectively. You can also use sodium sulfide for reduction. Add sodium sulfide to the reaction pot, add 3-chloro-4-methylnitrobenzene at 70~80\u00b0C, reflux for 4 hours, and the temperature is (110\u00b15)\u00b0C, and the reaction After completion, the mixture is separated into layers and distilled to obtain the finished product. <\/p>\n<\/p>\nPurpose<\/h2>\n\n Organic synthesis intermediate, used in the production of organic pigment intermediate 2B acid and pesticide chloromylon.\n <\/p>\n extended-reading:https:\/\/www.cyclohexylamine.net\/tris3-dimethylaminopropylamine-cas-33329-35-0\/<\/a><\/br>extended-reading:https:\/\/www.newtopchem.com\/archives\/44594<\/a><\/br>extended-reading:https:\/\/www.bdmaee.net\/organic-mercury-replacement-catalyst-nt-cat-e-at\/<\/a><\/br>extended-reading:https:\/\/www.bdmaee.net\/dabco-25-s-catalyst-cas280-57-9-evonik-germany\/<\/a><\/br>extended-reading:https:\/\/www.newtopchem.com\/archives\/917<\/a><\/br>extended-reading:https:\/\/www.cyclohexylamine.net\/pc-cat-tka-polyurethane-metal-carboxylate-catalyst-polycat-46\/<\/a><\/br>extended-reading:https:\/\/www.bdmaee.net\/wp-content\/uploads\/2022\/08\/37-4.jpg<\/a><\/br>extended-reading:https:\/\/www.morpholine.org\/cas-7560-83-0\/<\/a><\/br>extended-reading:https:\/\/www.newtopchem.com\/archives\/category\/products\/page\/93<\/a><\/br>extended-reading:https:\/\/www.bdmaee.net\/wp-content\/uploads\/2022\/08\/129-2.jpg<\/a><\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"Structural formula Business number 029Q Molecular formu…<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":48496,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[6],"tags":[15213],"gt_translate_keys":[{"key":"link","format":"url"}],"_links":{"self":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts\/48497"}],"collection":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/comments?post=48497"}],"version-history":[{"count":0,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts\/48497\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/media\/48496"}],"wp:attachment":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/media?parent=48497"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/categories?post=48497"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/tags?post=48497"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
