Method of preparation of Phenanthrene

by

The Phenanthrene is prepared by the following methods: 1. Haworth Synthesis of Phenanthrene: There are five steps involved in the Haworth Synthesis process: 2. By Dibenzal:  Phenanthrene can be produced by passing dibenzal through a red-hot tube. 3. From 2,2-Dimethyldiphenyl: Phenanthrene can be synthesized by cyclodehydrogenation of 2,2-Dimethyldiphenyl using sulfur. Conclusion: In conclusion, there are … Read more

Method of preparation of Naphthalene

by

Naphthalene constitutes the largest part of coal-tar, accounting for approximately 6-10%. The hydrocarbon was initially noticed as a residue in the condensers during the distillation of the naphtha portion, hence its name. It is typically obtained by cooling the middle oil fraction (160-230°), where naphthalene crystallizes. The raw crystals are removed through centrifugation. 1. From … Read more
