1,3-Diisopropylbenzene is an aromatic hydrocarbon with the formula C 6 H 4 (CHMe 2) 2 (Me = CH 3). It is one of three isomeric diisopropylbenzenes. This colorless liquid is prepared by thermal isomerization of 1,4-diisopropylbenzene over a solid acid catalyst. [1] It is the principal industrial precursor to resorcinol via the Hock rearrangement ...
[3] C 6 H 4 (CH(CH 3) 2) 2 + C 6 H 6 → 2 C 6 H 5 CH(CH 3) 2. The 1,3- and 1,4- isomers are mainly of interest as precursors to the respective dihydroxylbenzene derivatives, which exploits the Hock rearrangements. All three isomers form hydroperoxides, as is implicit in the Hock rearrangement, which are of interest as radical initiators for ...

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
