593-49-7 Usage
General Description
Heptacosane is a straight-chain alkane hydrocarbon with 27 carbon atoms and the molecular formula C27H56. It is a colorless, odorless solid at room temperature with a high melting point of 78°C. Heptacosane is insoluble in water but soluble in non-polar solvents such as hexane and chloroform. It is commonly found in the waxes of various plants and is also a component of some petroleum products. Heptacosane is used as an ingredient in cosmetic and personal care products, as well as in the manufacture of some specialty chemicals and pharmaceuticals. Additionally, it has potential applications in the production of lubricants, coatings, and adhesives due to its low reactivity and high stability.
Check Digit Verification of cas no
The CAS Registry Mumber 593-49-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 593-49:
(5*5)+(4*9)+(3*3)+(2*4)+(1*9)=87
87 % 10 = 7
So 593-49-7 is a valid CAS Registry Number.

Efficient heterogeneous dual catalyst systems for alkane metathesis

A fully heterogeneous and highly efficient dual catalyst system for alkane metathesis (AM) has been developed. The system is comprised of an alumina-supported iridium pincer catalyst for alkane dehydrogenation/olefin hydrogenation and a second heterogeneous olefin metathesis catalyst. The iridium catalysts bear basic functional groups on the aromatic backbone of the pincer ligand and are strongly adsorbed on Lewis acid sites on alumina. The heterogeneous systems exhibit higher lifetimes and productivities relative to the corresponding homogeneous systems as catalyst/catalyst interactions and bimolecular decomposition reactions are inhibited. Additionally, using a two-pot device, the supported Ir catalysts and metathesis catalysts can be physically separated and run at different temperatures. This system with isolated catalysts shows very high turnover numbers and is selective for the formation of high molecular weight alkanes.
