12-Tungstophosphate Acids: An Efficient, Green and Recyclable Photocatalyst in Carbon-Carbon Double Bond Isomerization on Linear Alpha Olefins

The accelerated UV visible photocatalytic carbon-carbon double bond isomerization of Linear Alpha Olefins (LAO) with 12-Tungstophosphate Acids (12-TPA) as an efficient, environmentally-friendly and recyclable catalyst was described, which produced the corresponding Linear Internal Olefins (LIO) in general high selectivity and high yields.

Synthesis of Alpha Olefins: Catalytic Decarbonylation of Carboxylic Acids and Vegetable Oil Deodorizer Distillate (VODD)

Decarbonylation of carboxylic acids provides an effective protocol for producing alpha olefins; however, previous literature has focused on the palladium-bisphosphine catalysts and has only sporadically studied the palladium-monophosphine catalyst. To investigate the catalytic activity of the palladium-monophosphine catalyst on decarbonylation of carboxylic acids, new monophosphine ligands were synthesized (NP-1, NP-2, CP-1 and CP-2). By employing (1–3 mol%) palladium-naphthylphosphine catalysts, various carboxylic acids were converted into corresponding alpha alkenes with good yields and selectivity within a short period of time. Vegetable oil deodorizer distillate (VODD), which is a by-product from the vegetable oil refinery process, was found to be rich in free fatty acids and there is great interest in turning vegetable oil deodorizer distillate into value-added compounds. It is noteworthy that our catalytic system could be applied to convert vegetable oil deodorizer distillate (VODD) into diesel-like hydrocarbons in a good yield.

Unravelling the K-promotion effect in a highly active and stable Fe5C2 nanoparticle for catalytic linear alpha-olefin production

C5−C13 linear alpha() olefins (LAOs) are high-value-added chemicals acknowledged by industry. However, using catalysts to elevate the activity and selectivity of LAOs remains a major challenge for Fischer–Tropsch synthesis (FTS)....

Renewable Linear Alpha-Olefins by Base-Catalyzed Dehydration of Biologically-Derived Fatty Alcohols

Base catalysts were studied for the dehydration of fatty alcohols to linear alpha olefins (LAOs). For the dehydration of 1-octanol to 1-octene, 15%Cs/SiO2 catalyst was 56% selective at 10% conversion....

Ethylene oligomerization into linear olefins over cobalt oxide on carbon catalyst

Here, we show that C4-C12 linear olefins, including linear alpha olefins, can be selectively produced from ethylene over a stable cobalt oxide on carbon catalyst. Both bulk and surface cobalt...

Modern trends in the processing of linear alpha olefins to technologically important products. Part 2

This review is a continuation of the first part, which considered modern trends in the processing of linear alpha olefins to (co)polymers of ethylene, anionic and non-ionic surfactants. Important directions in LAO processing are briefly described: alkylation leading to the formation of linear alkylbenzenes, oligomerization of alpha olefins to poly alpha olefins, sulfation yielding alpha olefin sulfonates, and other bulky processes.
