Paragraph 0020; 0035; 0044, (2019/01/23)
The invention discloses a method for continuously synthesizing meta-di-alkane aminophenol. The technical scheme includes that continuous diazotization or continuous diazonium salt hydrolysis or continuous diazotization and diazonium salt hydrolysis is carried on raw materials such as di-alkane aminophenol, sodium nitrite and sulfuric acid, and after-treatment such as extraction is carried out to obtain the meta-di-alkane aminophenol which is a product. The method has the advantages that the raw materials can come from sufficient sources and are low in cost, processes for synthesizing the meta-di-alkane aminophenol are high in safety, products are high in yield, the method is little in waste gas, wastewater and industrial residue pollution, is green and environmental friendly and has a highindustrialization value, and the like.

Paragraph 0022; 0030, (2019/01/08)
The invention provides a synthetic method for m-dialkylaminophenol. The synthetic method is characterized by comprising the following steps: step 1, adding an aqueous solution of sodium nitrite into an aqueous solution of sulfuric acid containing m-dialkylaminoaniline drop by drop at a temperature of -10 to 20 DEG C, and maintaining the obtained solution at a temperature of 5 to 30 DEG C for 1 to10 h after completion of the addition so as to obtain an aqueous solution of sulfuric acid containing m-dialkylaminoaniline diazohydrosulfate; and step 2, directly heating aqueous solution of sulfuricacid containing m-dialkylaminoaniline diazohydrosulfate to 45-110 DEG C, maintaining the solution at the temperature for 1-18 h, allowing m-dialkylaminoaniline diazohydrosulfate to undergo the hydrolysis reaction of a diazonium salt, and successively carrying out cooling and post-treatment so as to obtain the product dialkylaminophenol, wherein sulfuric acid needed in the first step and the second step is totally added in one shot in a first-step reaction, and the first-step diazotization reaction and the second-step hydrolysis reaction of the diazonium salt are carried out step by step in one pot. The method of the invention has the characteristics of low raw material price, sufficient raw material sources, high safety, high product yield, less three-wastes pollution and the like, and has high industrialization value.
