General Description

Dinonyl ether, also known as di-nonyl ether, is a chemical compound that belongs to the class of organic compounds known as alkyl aryl ethers. It is a colorless liquid with a slight floral odor, and it is insoluble in water but soluble in organic solvents. Dinonyl ether is commonly used as a plasticizer in the production of plastics, such as PVC, to improve their flexibility and durability. It is also used as a solvent in various industries, including inks, paints, and adhesives. Additionally, dinonyl ether is used as a processing aid in the production of rubber and as a lubricant additive in the automotive and industrial sectors. However, like many organic compounds, dinonyl ether should be handled carefully as it may be harmful if ingested, inhaled, or comes into contact with the skin.

Effect of Alcohol Structure on the Kinetics of Etherification and Dehydration over Tungstated Zirconia

Linear and branched ether molecules have attracted recent interest as diesel additives and lubricants that can be produced from biomass-derived alcohols. In this study, tungstated zirconia was identified as a selective and green solid acid catalyst for the direct etherification of primary alcohols in the liquid phase, achieving ether selectivities of >94 % for C6–C12 linear alcohol coupling at 393 K. The length of linear primary alcohols (C6–C12) was shown to have a negligible effect on apparent activation energies for etherification and dehydration, demonstrating the possibility to produce both symmetrical and asymmetrical linear ethers. Reactions over a series of C6 alcohols with varying methyl branch positions indicated that substituted alcohols (2°, 3°) and alcohols with branches on the β-carbon readily undergo dehydration, but alcohols with branches at least three carbons away from the -OH group are highly selective to ether. A novel model compound, 4-hexyl-1dodecanol, was synthesized and tested to further demonstrate this structure–activity relationship. Trends in the effects of alcohol structure on selectivity were consistent with previously proposed mechanisms for etherification and dehydration, and help to define possible pathways to selectively form ethers from biomass-derived alcohols.

Process for the preparation of medium and long chain dialkyl ethers and catalysts

Dehydration catalyst for 6-22C alcohols at raised temperature to mid- and long-chain dialkyl ethers comprises a tin haloalkane sulfonate.

A NOVEL METHOD FOR THE PREPARATION OF SYMMETRICAL AND UNSYMMETRICAL ETHERS. TRITYL PERCHLORATE PROMOTED REDUCTION OF CARBONYL COMPOUNDS WITH TRIETHYLSILANE

In the presence of a catalytic amount of trityl perchlorate, symmetrical ethers are prepared from aldehydes and triethylsilane, and unsymmetrical ethers are also obtained from carbonyl compounds, alkoxytrimethylsilanes and triethylsilane, in good yields, respectively.
