Preparation method of 1,3,5-trialkoxy-2,4,6-trinitrobenzene
-
Paragraph 0024-0059, (2021/10/27)
The invention discloses a preparation method of 1,3,5-trimethoxy-2,4,6-trinitrobenzene. The method comprises the following steps: dissolving trinitrophloroglucinol in an alkylating reagent with the mass being 5 times that of the trinitrophloroglucinol to obtain a raw material solution; pumping the raw material solution into a continuous flow tubular reactor I, and reacting at 80-110 DEG C for 5-30 minutes to obtain an alkylation reaction solution; feeding the alkylation reaction liquid into a continuous flow tubular reactor II for cooling for 5-10 minutes, wherein the cooling temperature is 20-30 DEG C; and taking out the product, adding the product into a devitrification solution, and performing cooling, devitrifying, stirring, filtering and drying to obtain a product 1,3,5-trimethoxy-2,4,6-trinitrobenzene, wherein the alkylating reagent is a methylation reagent or an ethylation reagent or a propylation reagent. A continuous flow technology is used for inhibiting side reaction, the yield and purity of a target product are improved, and the post-treatment process is greatly simplified. The method can easily control reaction process and is suitable for industrial production.

Straessler, Nicholas A.
experimental part, p. 2513 - 2519 (2010/09/14)
Conditions for the mild and efficient nitration of phloroglucinol (1,3,5-trihydroxybenzene), 5-methoxyresorcinol, 3,5-dimethoxyphenol, and 1,3,5-trimethoxybenzene have been developed. Yields of the trinitro derivatives are excellent (~90%) for systems hav
