2-Ethylisohexyl Acetate Form S. G. 20°/20°C Boiling Range, 760mm.
For those who are developing better paint driers, viny! stabilizers, or plasticizers or who are intrigued with ore extradants, we recommend this branched 8-carbon acid for investigation. Its soaps make interesting gelling agents, too.

liquid 0.865-0.870 186-195°C
Here's a new ester solvent with a very low evaporation rate and very low water solubility—a valuable combination of properties for multi-color lacquer and emulsion formulations, for instance.

liquid 0.8001 90.3°C
The possibilities here are limited only by the imagination—a vinyl linkage and a cyanide radical on a short molecule.
2,5-Dihydroxybenzoquinone Form solid Melting Point 216°C (Decomposed) Quality Technical grade From metal chelating to insecticide manufacture anyone interested in quinone compounds will find this one easy to workwith—decidedly more stable than most and less irritating to skin and eyes.
