Formation of benzene from alkane
WebHydrocarbons: Hydrocarbons are compounds composed of carbon and hydrogen atoms, containing C-C and C-H bonds only. Hydrocarbons are further subdivided into the following homologous series: Alkanes: An alkane or paraffin is an acyclic saturated hydrocarbon with the general formula C n H 2n+2 where n= number of carbon atoms. It consists of all C ... http://rlhxxb.sxicc.ac.cn/cn/article/doi/10.1016/S1872-5813(23)60357-3

WebWhen one or both alkene carbons contain two alkyl groups, ozonolysis generates one or two ketones. The ozonolysis of 1,2‐dimethyl propene produces both 2‐propanone (a ketone) … Benzene is an organic chemical compound with the molecular formula C6H6. The benzene molecule is composed of six carbon atoms joined in a planar ring with one hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon. Benzene is … See more Discovery The word "benzene" derives from "gum benzoin" (benzoin resin), an aromatic resin known since ancient times in Southeast Asia; and later to European pharmacists and … See more Many important chemical compounds are derived from benzene by replacing one or more of its hydrogen atoms with another functional group. Examples of simple benzene derivatives are phenol, toluene, and aniline, abbreviated PhOH, PhMe, and PhNH2, … See more Four chemical processes contribute to industrial benzene production: catalytic reforming, toluene hydrodealkylation, toluene disproportionation, and steam cracking etc. According to the ATSDR Toxicological Profile for benzene, between 1978 and 1981, … See more The most common reactions of benzene involve substitution of a proton by other groups. Electrophilic aromatic substitution is a general method … See more X-ray diffraction shows that all six carbon-carbon bonds in benzene are of the same length, at 140 picometres (pm). The C–C bond lengths are greater than a double bond (135 pm) but … See more Benzene is used mainly as an intermediate to make other chemicals, above all ethylbenzene (and other alkylbenzenes See more Benzene is classified as a carcinogen, which increases the risk of cancer and other illnesses, and is also a notorious cause of bone marrow failure.
