Claims (1)

Вещества, имеющие структуру арилфосфинов или производных арилфосфинов с атомом кислорода или атомом серы, непосредственно связанным с атомом фосфора, содержат цепи полностью фторированного простого алкилового эфира (перфторалкилового эфира). Эти цепи связаны с бензольным кольцом неперфторированной мостиковой связью, и их получают способом, значительно снижающим себестоимость этих продуктов, и пригодны для использования в качестве стабилизаторов перфторполиэфирных масел и смазок, предотвращающих их разложение в присутствии металлов, а также коррозию этих металлов, например алюминия, титана, ванадия или их сплавов, при работе в условиях окисляющей среды и высокой температуры.Substances having the structure of arylphosphines or derivatives of arylphosphines with an oxygen atom or a sulfur atom directly bonded to a phosphorus atom contain chains of fully fluorinated alkyl ether (perfluoroalkyl ether). These chains are connected to the benzene ring of a non-perfluorinated bridge bond, and they are produced by a method that significantly reduces the cost of these products, and are suitable for use as stabilizers for perfluoropolyether oils and lubricants that prevent their decomposition in the presence of metals, as well as corrosion of these metals, such as aluminum, titanium , vanadium or their alloys, when working in conditions of an oxidizing environment and high temperature.
