Cycloheneicosane is a cyclic alkane hydrocarbon with the molecular formula C21H40. It consists of 21 carbon atoms arranged in a closed ring structure, with each carbon atom bonded to two adjacent carbon atoms and two hydrogen atoms. cycloheneicosane is a member of the cycloalkane family, which are cyclic versions of the linear alkanes. Cycloheneicosane is a colorless, odorless, and non-polar liquid at room temperature. Due to its large ring size, it exhibits relatively low reactivity and is mainly used for research purposes in organic chemistry. Its properties, such as boiling point and solubility, are influenced by the ring structure and the number of carbon atoms, making it an interesting subject for studying the effects of ring size on the physical and chemical properties of cyclic hydrocarbons.

296-78-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 296-78-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,9 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 296-78:
(5*2)+(4*9)+(3*6)+(2*7)+(1*8)=86
86 % 10 = 6
So 296-78-6 is a valid CAS Registry Number.

Metathesis of cyclic alkanes catalyzed by the new surface complex [(ΞSiO)W(Me)5] affords a wide distribution of cyclic and macrocyclic alkanes. The major products with the formula CnH2n are the result of either a ring contraction or ring expans

Catalytic ring expansion, contraction, and metathesis-polymerization of cycloalkanes

Tandem dehydrogenation-olefin-metathesis catalyst systems, comprising a pincer-ligated iridium-based alkane dehydrogenation catalyst and a molybdenum-based olefin-metathesis catalyst, are reported to effect the metathesis-cyclooligomerization of cyclooctane and cyclodecane to give cycloalkanes with various carbon numbers, predominantly multiples of the substrate carbon number, and polymers.
