Phloroglucin hcl
WebbAbstract. The invention discloses a preparation method of phloroglucinol, which comprises the following steps: dissolving resorcinol in reaction solvent, then adding an N-bromosuccinimide solution, heating to perform bromination reaction, and then treating to obtain 4-bromoresorcinol; adding the obtained 4-bromoresorcinol into a container ... Webb10.1 (40 mmole) 1,3,5-triuredio-benzene was reacted with (11.3 g) 0.31 mole HCl = 31.5 g 36% hydrochloric acid (corresponding at the end of the reaction to an HCl excess of 2.5 g = 0.5% HCl solution) in a 1-liter autoclave lined with Teflon for 16 hours at 180° C and a characteristic partial pressure of 20 atm. under vigorous stirring.
