Iridium‐Catalyzed Domino Hydroformylation/Hydrogenation of Olefins to Alcohols: Synergy of Two Ligands
chance to develop new catalytic systems before empirical studies were undertaken. Then the iridium-catalyzed domino hydroformylation/reduction of olefins to alcohols under water–gas shift reaction conditions was studied as an example. Two different ligands (L1 and L10) applied at the same time improved alcohol yields and verified the computational model.

The present invention relates to a process for the production of carboxylic esters by reaction of carboxylic acids and/or carboxylic anhydrides with at least one alcohol selected from alkanols having at least 5 carbon atoms, cycloalkanols, and alkoxy-alkanols, in the presence of an acidic esterification catalyst. The invention further relates to the use of the resultant carboxylic esters as plasticizers or in a plasticizer composition for thermoplastic polymers and elastomers.
Cleaning compositions are described comprising mid-range alkoxylate surfactants or blends of alkoxylate surfactants, and their use as cleaners for triglycerides and cross-linked triglycerides, formula stabilization agents, agents for ultra-concentrated cleaning formulations, pre-wash spotters, detergents, agricultural adjuvants, hard surface cleaning, and emulsifiers.
A mixture of octanols, nonanols and decanols is useful for the preparation of alkoxylates, which alkoxylates may be used as surfactants, which surfactants have surprisingly good biodegradability.
