Description
(54) СПОСОБ ПОЛУЧЕНИЯ ПОЛИОЛЕФИНОВ(54) METHOD FOR OBTAINING POLYOLEFINS
1one
Изобретение относитс к химии поли-, мерен, а именно к получению полиоле ,финов, которые могут быть использованы в качестве базовых компонентов смазочных Масел.The invention relates to the chemistry of poly-, dimensional, namely the production of polyol, finons, which can be used as the basic components of lubricating oils.
Известен способ получени полнолефи- нов путем полимеризации о(.-олефинов в присутствии перекисных соединений .A known method of producing full olefins by polymerizing o (.- olefins in the presence of peroxide compounds.
Однако конечный продукт не обладает комплексом свойств, необходимых дл смазочных масел,However, the final product does not possess the complex properties required for lubricating oils,
Наиболее близким к изобретению вл етс способ получени полиолефинов полимеризацией С -С -альфа-оЛефинов в массе с применением в качестве катализатора соединений алюмини 2.Closest to the invention is a method for producing polyolefins by polymerization of C-C-alpha-olefins in bulk using aluminum compounds as a catalyst.
Полимеризацию oL-олефинов осуществл ют в присутствии смеси алюминийо; ганических соединений, вз тых в количестве до 5 масс % на cL- олефины.The polymerization of oL-olefins is carried out in the presence of an aluminum mixture; chemical compounds taken in an amount of up to 5 mass% per cL-olefins.
В предварительно приготовленнЗЧо смесь апюминииорганических соединений подаиут сырье - альфа-олефины, Реак-In the previously prepared mixture of organic organo compounds, the raw material is alpha-olefins,
цию провод т при температурном режиме ЭО-ИО С.This is carried out at a temperature mode of EO-IO C.
Однако но известному способу получают полиолефины, которые характеризуютс высокой в зкостью при низких температурах.However, polyolefins, which are characterized by high viscosity at low temperatures, are produced by a known method.
Цель изобретени - улучшение в зкостно-температурных свойств.The purpose of the invention is to improve the viscosity-temperature properties.
Эта ель достигаетс тем, что последовательно осуществл ют введение в предварительно нагретую до 7О-8ОС мономерную смесь 0,7-1,5 масс.% от мономерной смеси алкилалюминийхлорида, повышение температуры до 150-17О С, выдерживание ЗО - 40 мин, введение О,3 - 1,О масс.% от реакционной смеси хлористого алюмини и проведение процесса полимеризации при 11О-13О С.This spruce is achieved by successively introducing a monomer mixture of 0.7-1.5 wt.% From an alkyl aluminum chloride monomer mixture into the preheated to OO-8OC, raising the temperature to 150-17 ° C, keeping the DOR for 40 minutes, introducing O , 3 - 1, About wt.% From the reaction mixture of aluminum chloride and carrying out the polymerization process at 11O-13O C.
Порционна подача компонентов катализатора в олефины и определенный температурный режим полимеризации позвол ют синтезировать полиолефины, обладающие невысокой в зкостью при низких теппературах.The batch supply of the catalyst components to olefins and a certain temperature mode of polymerization make it possible to synthesize polyolefins with low viscosity at low temperatures.
