Description
;ii Изобретение относитс к производству катализаторов , в частности к катализатору на основе комплексов металлов платиновой группы дл гидрировани и/или изомеризации непредельных органических соединений.; ii The invention relates to the production of catalysts, in particular to a catalyst based on platinum-group metal complexes for the hydrogenation and / or isomerization of unsaturated organic compounds.
Известен катализатор, например, дл гидрировани непредельных органических соединений , представл ющий СОбой комплексное соединение металла платиновой группы, лигандом которого вл етс соединение, склонное к бензоидно-хиноидной мезомерии, например флуоросцеин.A catalyst is known, for example, for the hydrogenation of unsaturated organic compounds, which is a SOBY complex compound of a platinum group metal whose ligand is a compound prone to benzoid-quinoid mesomerism, such as fluorocein.
Однако этот катализатор не обладает до Ётаточно высокой активностью.However, this catalyst does not have high activity.
Предлагаетс в качестве катализатора примен ть диалкилсульфоксидные комплексы металлов платиновой группы в восстановленной форме.It is proposed to use dialkyl sulfoxide complexes of platinum group metals in reduced form as a catalyst.
Этот катализатор обладает высокой аКтивНоетью не только при гидрировании, но и при изомеризации непредельных органических соединений .This catalyst has a high level of activity not only in hydrogenation, but also in the isomerization of unsaturated organic compounds.
Элементарный состав комплесного диметилсульфоксидного катализатора, например палладиевого, следующий:The elemental composition of the complex dimethyl sulfoxide catalyst, for example, palladium, is as follows:
ВМС ОNavy O
DTICODTICO
где п - равно приблизительно 6.where n is about 6.
В ИК-спектре этого комплекса наблюдаетс очень интенсивна полоса поглощени валентных колебаний S-О около 1100 см, котора сдвинута в область более высоких частот по сравнению со свободным диметилсульфоксидом (v5-0 1000 еж-). Это свидетельствует о том, что молекула диметилсульфоксида координирована на атоме паллади через атом серы.In the IR spectrum of this complex, a very intense absorption band of S-O oscillations around 1100 cm is observed, which is shifted to higher frequencies compared to free dimethyl sulfoxide (v5-0 1000 hedgehog). This suggests that the dimethyl sulfoxide molecule is coordinated on the palladium atom through the sulfur atom.
Пример 1. Деметилсульфоксидные комплексы готов т по следующей методике: на пример, 1 г Pd Cl2 растирают с 2 г диметйлсульфоксида . Образующийс желтый кристаллический осадок фильтруют и промывают этиловым спиртом,Example 1. Demethylsulfoxide complexes are prepared according to the following procedure: for example, 1 g of Pd Cl2 is triturated with 2 g of dimethyl sulfoxide. The resulting yellow crystalline precipitate is filtered and washed with ethyl alcohol,
Пример 2. 0,03 г диметилсульфоксйдНбго комплекса паллади или рутени раствор ют в 20 мл диметилсульфоксида и в течение 5-30 мин обрабатывают 0,1 г гидрида лити в инертной атмосфере (азот или аргон) при 5-40°С. Раствор катализатора хран т в атмосфере инертного газа.Example 2. 0.03 g of dimethylsulfoxide-dyed palladium or ruthenium complex is dissolved in 20 ml of dimethyl sulfoxide and treated with 5 g of lithium hydride in an inert atmosphere (nitrogen or argon) for 5-30 minutes at 5-40 ° C. The catalyst solution is stored in an inert gas atmosphere.
При м е р 3. 0,03 г диметилсульфоксидного комплекса роди или платины раствор ют в 30 мл смеси спирта с диметилсульфоксидом (1:1). Раствор в течение 15-20 мин обрабатывают 1,0 г гидразина при 10-40°С в инерт-ной атмосфере. iPacTBop катализатора хран т в атмосфере инертного газа.Example 3. 0.03 g of dimethyl sulfoxide complex of rhodium or platinum is dissolved in 30 ml of a mixture of alcohol and dimethyl sulfoxide (1: 1). Within 15-20 minutes, the solution is treated with 1.0 g of hydrazine at 10-40 ° C in an inert atmosphere. iPacTBop catalysts are stored in an inert gas atmosphere.
П р и м е р 4. 0,05 г диметилсульфоксндного комплекса ириди или роди раствор ют в 30 мл N-метилпирролидона, и в течение 10-EXAMPLE 4: 0.05 g of the dimethyl sulfox complex of the iridium or rhodium complex is dissolved in 30 ml of N-methylpyrrolidone and within 10 to
