METHOD OF PRODUCING ADAMANTANE |
摘要 |
FIELD: chemistry.SUBSTANCE: invention relates to a method of producing adamantane (tricyclo[3.3.1.1]decane) via isomerisation in two steps using endo-tetrahydrodicyclopentadiene (tricyclo[5.2.1.0]decane) or endo-tetrahydrodicyclopentadiene (tricyclo[5.2.1.0]decane) and exo-tetrahydrodicyclopentadiene (tricyclo[5.2.1.0]decane) as the starting substance. The method involves the following steps: using one HF catalyst or two catalysts from HF catalysts and BFcatalysts without a solvent, at the first step for isomerisation of endo-tetrahydrodicyclopentadiene (tricyclo[5.2.1.0]decane) to exo-tetrahydrodicyclopentadiene (tricyclo[5.2.1.0]decane); and using a HF catalyst and a BFcatalyst without a solvent at the second step for isomerisation of exo-tetrahydrodicyclopentadiene (tricyclo[5.2.1.0]decane) to adamantane (tricyclo[3.3.1.1]decane). The two-step isomerisation reaction takes place in a liquid phase, obtained in a reaction of a liquid-phase solution, and output of adamantane is controlled such that it is equal to or less than total solubility of adamantane in exo-tetrahydrodicyclopentadiene and solubility of adamantane in endo-tetrahydrodicyclopentadiene at the second isomerisation step.EFFECT: use of the disclosed method enables to obtain adamantane without deposit thereof in form of a solid residue even without a solvent.12 cl, 5 ex, 1 dwg |
