CS 2 once was manufactured by combining carbon (or coke) and sulfur at 800–1000 °C. [13] C + 2S → CS 2. A lower-temperature reaction, requiring only 600 °C, utilizes natural gas as the carbon source in the presence of silica gel or alumina catalysts: [9] 2 CH 4 + S 8 → 2 CS 2 + 4 H 2 S. The reaction is analogous to the combustion of ...
C2 domain, a protein structural domain; C2 regulatory sequence for the insulin gene; Apolipoprotein C2, a human apolipoprotein; In human anatomy, C2 may refer to: Cervical vertebra 2, the axis, one of the cervical vertebrae of the vertebral column
Homochirality is an obvious characteristic of life on Earth, yet extraterrestrial samples contain largely racemic compounds. [7] It is not known whether homochirality existed before life, whether the building blocks of life must have this particular chirality, or whether life must be homochiral at all.
Diatomic carbon (systematically named dicarbon and 1λ 2,2λ 2-ethene), is a green, gaseous inorganic chemical with the chemical formula C=C (also written [C 2] or C 2). It is kinetically unstable at ambient temperature and pressure, being removed through autopolymerisation .
CCS can be a ligand. It can form an asymmetrical bridge between two molybdenum atoms in Mo2(μ,σ(C):η 2 (C′S)-CCS)(CO) 4 (hydrotris(3,5-dimethylpyrazol-1-yl)borate) 2 In this one carbon atom has a triple bond to a molybdenum and the other has a double bond to the other molybdenum atom, which also has a single bond to the sulfur atom.
The C 2 symmetry of ligands limits the number of possible reaction pathways and thereby increases enantioselectivity, relative to asymmetrical analogues. C 2-symmetric ligands are a subset of chiral ligands. Chiral ligands, including C 2-symmetric ligands, combine with metals or other groups to form chiral catalysts.
This finding is an extension of the Miller–Urey experiment, and it is suggested that carbonyl sulfide played a significant role in the origin of life. [ 17 ] In ecosystem science, [ 18 ] are increasingly being used to describe the rate of photosynthesis .
Carbon suboxide, or tricarbon dioxide, is an organic, oxygen-containing chemical compound with formula C 3 O 2 and structure O=C=C=C=O. Its four cumulative double bonds make it a cumulene. It is one of the stable members of the series of linear oxocarbons O=C n =O, which also includes carbon dioxide (CO 2) and pentacarbon dioxide (C 5 O 2).
