| titleOfInvention | Preparation of diarylalkane compound |
| abstract | PURPOSE: To obtain the titled compound useful as a thermal medium, insulation oil, etc., in high selectivity and yield, by reacting toluene with an aldehyde in sulfuric acid having a specific concentration keeping the concentration of the aldehyde at a specific level, at a specific temperature. n CONSTITUTION: The odorless, colorless and transparent diarylalkane compound of formula III (R 1 and R 2 are H or CH 3 ) having excellent solubility can be prepared by reacting toluene and/or xylene of formula I (R is H or CH 3 ) with a 3W 10C aldehyde of formula II (n is 2W9), especially ≥4C aldehyde, in the presence of sulfuric acid of 86W96wt% concentration, at -40W+15°C, keeping the aldehyde concentration in the reaction system to ≥3wt%. n EFFECT: When a mixture of o-, m- and p-xylene isomers is used as the raw material, the concentration of p-xylene can be prevented owing to the extremely low reactivity of p-xylene. n USE: Solvent of dye for pressure-sensitive copying paper, etc. n COPYRIGHT: (C)1986,JPO&Japio |
