摘要： PURPOSE:To obtain the subject compound in high efficiency by separating p- isomer from an isomer mixture of cresol by adsorptive separation, etc., contacting the residual mixture with a solid acid catalyst in the presence of phenol to effect transalkylation and isomerization and recycling the phenol and cresol to the separation step. CONSTITUTION:An isomer mixture of cresol is subjected to adsorptive separation with an adsorptive separation apparatus 1 preferably using a zeolite-type material as an adsorbent and phenol as a desorption agent. The extract composed of p-cresol and phenol is transferred through a line 8 to the 1st distillation column 2. The raffinate left after the separation of p-cresol and composed of cresol isomers and phenol is sent through a line 9 to a transalkylation and isomerization reactor 3 and the reaction product is transferred through a line 14 to the 2nd distillation column 4. Phenol and cresol are recycled via a line 7 to the adsorptive separation apparatus 1. p-Cresol is separated as a bottom fraction of the distillation column 2 and recovered as the product through a line 11.

摘要： PURPOSE:To advantageously obtain the title compound useful as a raw material for agricultural chemicals or photographic agents, by subjecting 2,4-dichloro-3- methyl-6-tertiary butylphenol as a raw material with an alkylbenzene to rearrangement reaction in the presence of a specific catalyst. CONSTITUTION:2,4-Dichloro-3-methyl-6-tertiary butylphenol is used as a raw material and subjected to rearrangement reaction with an alkylbenzene in the presence of an aluminum halide or a complex of the alkylbenzene and the aluminum halide as a catalyst to give the aimed compound. The amount of the alkylbenzene used is preferably about 1-10mols based on 1mol of the raw material and the amount of the catalyst used is preferably 0.05-0.7mol based on 1mol of the raw material. The raw material is synthesized by chlorinating 3-methyl-6-tertiary butylphenol or 3-methyl-4,6-ditertiary butylphenol.

摘要： PURPOSE: To prepare the titled two compounds simultaneously, by subjecting 3,5,3',5'-tetra-t-butyl-4,4'-biphenol and phenol to a transalkylation reaction using activated clay as a catalyst.
CONSTITUTION: 3,5,3',5'-Tetra-t-butyl-4,4'-biphenol is reacted with phenol (preferably in a ratio of 1:2W20) in the presence of an activated clay catalyst at about 150W220°C under heating, so that the t-butyl group is subjected to transalkylation on the meta position of phenol, to give 4,4'-biphenol and meta-t-butylphenol (mBP) simultaneously.
EFFECT: mBP can be formed preferentially in high selectivity ratio.
USE: 4,4'-Biphenol is a raw material for heat-resistant synthetic resin, and mBP is an intermediate for synthesizing drugs, agricultural chemicals, etc.
