Process for purification of crude resorcinol |
| abstract |
In a process for purification of crude resorcinol derived from an acid-cleavage product of m-diisopropylbenzene dihydroperoxide and containing impurities having higher boiling points than resorcinol is, the recrystallization of said crude resorcinol from a mixed solvent consisting of (a) about 0.5 to about 5 times the weight of resorcinol of an aromatic hydrocarbon which contains 6 to 10 carbon atoms and is liquid at 20 DEG C., and (b) about 0.1 to about 0.7 time the weight of resorcinol of at least one compound selected from the group consisting of alkyl phenols having a C1-C4 alkyl group and acyl phenols derived from C2-C4 aliphatic monocarboxylic acids. |
