In organic chemistry, terminal alkenes (alpha-olefins, α-olefins, or 1-alkenes) are a family of organic compounds which are alkenes (also known as olefins) with a chemical formula C x H 2x, distinguished by having a double bond at the primary, alpha (α), or 1-position. [1]

Straight-chain terminal alkenes, also called linear alpha olefins (LAO) or normal alpha olefins (NAO), are alkenes (olefins) having a chemical formula C n H 2n, distinguished from other alkenes with a similar molecular formula by being terminal alkenes, in which the double bond occurs at the alpha (α-, 1-or primary) position, and by having a ...

2022年3月3日 · We recently introduced a broadly tunable synthesis of linear α-olefins and report here on the catalytic reaction of an α-olefin with two ethylene molecules. One of the two ethylene molecules forms a 4-ethyl branch and the other a new terminal C–C double bond rendering the initial olefin C2-elongated.

2021年10月1日 · Linear alpha olefins (LAOs) are hydrocarbons with the chemical formula C n H 2n, characterized by linear chains and one double bond at the alpha position (Figure 1). Such hydrocarbons are important chemical intermediates, widely used in several industrial and consumer products according to carbon number and chemical structure.

2023年5月25日 · Alpha olefins, a versatile class of unsaturated hydrocarbons, have become increasingly important in various industries due to their unique chemical properties and wide-ranging applications.

In organic chemistry, an alkene, or olefin, is a hydrocarbon containing a carbon–carbon double bond. [1] The double bond may be internal or at the terminal position. Terminal alkenes are also known as α-olefins.

Linear α-Olefins (LAO) are used in several applications in chemical industry. Especially 1-Butene and 1-Hexene are highly valuable comonomers for polyolefins.

2024年9月22日 · Alphaolefins (or olefins) are a family of organic compounds which are alkenes (also known as olefins) with a chemical formula CxH2x, distinguished by having a double bond at the primary or alpha position.

2021年7月2日 · Linear alpha olefins (LAO) are a class of chemical compounds used in the production of such high-demand products as plasticizers, synthetic lubricants, surfactants, and co-polymers with improved performance.

Beginning in the 1970s, so-called linear alpha olefins (LAOs; distinguished by the double bond occurring on the first, or alpha, carbon atom in the unbranched chain) were produced through polymerization (specifically, oligomerization) and olefin metathesis, which together formed the basis of the Shell higher olefin process (SHOP).
