Анотация: In the conditions of an interphase catalysis in the presence of crown-ether reactions of oxidation of primary alcohols, saturated hydrocarbons (C4 – C10) and saturated chlorhydrocarbons are investigated and easy, effective and new method for obtaining saturated organic acids is offered. Use of crown-ether in the offered method allows to carry out process at low temperature and mild conditions, at the same time the same portions of crown-ether can be used many times without special cleaning and easily regenerated. The new simple technique is developed for cleaning and separation of crown-ether from reaction mixture after carrying out oxidation reaction. The reaction of oxidation of primary alcohols, saturated hydrocarbons (C4–C10) and saturated chlorhydrocarbons was carried out in two-phase heterogeneous system within 20-50 min. Quantity ratio of initial product: KMnO4: DB18K6A, was 0.1: 0.3-0.4: 0.003-0.004. The process is smoothly carried out at 1050C -1600C temperature interval (against 4500C -5000C in usual conditions in the lack of the interphase catalyst) without formation of chlorine containing waste and also poisonous products. The listed data provide the maximum yield of a target product.
