Usage

General Description

1-Hexadecene is a long-chain, unsaturated hydrocarbon with a 16-carbon backbone and a double bond at the 1st position. It is commonly used as a starting material for the synthesis of various organic compounds, such as surfactants, detergents, lubricants, and plasticizers. 1-Hexadecene is also used as a solvent in the production of polymers and as a flotation agent in mineral processing. Additionally, it can be found in some personal care products and cosmetics, where it acts as an emollient and skin-conditioning agent. 1-Hexadecene is considered to be relatively low in toxicity and is not known to cause any harmful effects to human health or the environment.

LA PHOTOLYSE DES ACIDES ET DES ESTERS

Irradiation of saturated acids or esters below 220 nm leads to a Norrish-II cleavage or an 1,2-elimination in preparatively useful yields; this is illustrated by several efficient degradations, including that of the side-chain of bile acids.

Norrish type II reactions of acyl azolium salts

The photochemical reactivity of acyl azolium salts derived from aliphatic carboxylic acids has been investigated. These species, which serve as models for intermediates generated in N-heterocyclic carbene (NHC) organocatalysis, undergo Norrish type II elimination reactions under irradiation with UVA light in analogy to structurally related aromatic ketones. Moreover, efficient Norrish-Yang cyclization was observed from an adamantyl-substituted derivative. These results further demonstrate the ability of NHCs to influence the absorption properties and photochemical reactivity of carbonyl groups during a catalytic cycle.

Surfactant-Free Synthesis of Ultrafine Pt Nanoparticles on MoS2Nanosheets as Bifunctional Catalysts for the Hydrodeoxygenation of Bio-Oil

Hydrodeoxygenation (HDO) of bio-oil is a crucial step for improving the bio-fuel quality, but developing highly dispersed Pt-based catalysts with high selectivity for target alkanes remains a great challenge. This study presents a fast surfactant-free method to prepare the MoS2-supported Pt catalyst for HDO. Ultrafine Pt nanoparticles with sizes of 5 nm can be readily grown on chemically exfoliated MoS2 nanosheets (NSs) via the direct microwave-assisted thermal reduction. The obtained Pt NPs/MoS2 composites show excellent catalytic performance in the conversion of palmitic acid, and the best selectivity (also the yield) of hexadecane and pentadecane is 80.56 and 19.43%, respectively.
