OXIRANE COMPOUNDS PREPARING |
摘要 |
FIELD: organic chemistry, chemical technology. ^ SUBSTANCE: invention proposes a method for synthesis of oxirane compounds comprising the following steps: (i) oxidation of alkylaryl to yield alkylaryl hydroperoxide; (ii) contacting at least lesser part of alkylaryl hydroperoxide prepared at the step (i) with olefin in the presence of catalyst to yield oxirane compound and alkylaryl hydroxyl; (iii) separation of oxirane compound from the reaction product from the step (ii), and (iv) contacting at least part of the reaction product no containing oxirane compound with hydrogen to yield alkylaryl and at least of part of the latter is re-circulated to the step (i) and wherein alkylaryl means an alkylaryl compound representing di-(isopropyl)-benzene. Invention provides the possibility for preparing oxirane compound without the necessity for preparing other compounds and reducing the amount of the parent alkylaryl. ^ EFFECT: improved method of synthesis. ^ 3 cl |
