Description
Известные в научной и патентной литературе способы гидрировани заключаютс в том, что нафталин или другой подобный продукт подвергаетс гидрогенизации под давлением водорода , преимущественно в присутствии различных катализаторов. Однако, скорость этого процесса в большинстве случаев крайне мала, так как при обычных в технике давлени х повышение температуры лимитируетс состо нием равновеси гидрировани исходного продукта.Hydrogenation methods known in the scientific and patent literature consist in the fact that naphthalene or another similar product undergoes hydrogenation under hydrogen pressure, preferably in the presence of various catalysts. However, the speed of this process is in most cases extremely low, since at conventional pressures in a technique the temperature increase is limited by the equilibrium state of the hydrogenation of the starting product.
Наиболее целесообразным вл етс применение в качестве катализаторов фосфорно-молибденово аммониевой соли с сол ми фосфорной кислоты (франц. пат. № 725070).The most appropriate is the use of phosphoric-molybdenum ammonium salt with salts of phosphoric acid as catalysts (French Pat. No. 725070).
Согласно насто щему изобретению, предлагаетс вести процесс гидрировани нафталина и других веществ с применением вышеназванных катализаторов в две стадии: 1-гидрирование исходного продукта при более низкой температуре без расщеплени и 2-расщепление гидрированных продуктов при более высокой температуре.According to the present invention, it is proposed to conduct the process of hydrogenation of naphthalene and other substances using the above catalysts in two stages: 1-hydrogenation of the starting product at a lower temperature without splitting and 2-splitting of the hydrogenated products at a higher temperature.
Пример 1. 200 г нафталина нагреваютс под начальным давлением водорода в 100 атм. в течение двух часов во вращающемс автоклаве емкостью в 5 литров при температуре 475-480 с 20 г катализатора, полученного из фосфорно-молибденово-аммониевой соли.Example 1. 200 g of naphthalene are heated under an initial hydrogen pressure of 100 atm. within two hours in a rotating autoclave with a capacity of 5 liters at a temperature of 475-480 with 20 g of catalyst obtained from the phosphorus-molybdenum ammonium salt.
В продукте реакции 60% фракций, кип щих до 180°, содержащих до 70° ароматических углеводородов, немного бензола и, главным образом, толуол и и ксилолы. Остальные фракции составл ют тетралин и декалин с примесью нафталина в количестве 3-5%.In the reaction product there are 60% of fractions boiling up to 180 °, containing up to 70 ° aromatic hydrocarbons, a little benzene and, mainly, toluene and xylenes. The remaining fractions are tetralin and decalin mixed with naphthalene in the amount of 3-5%.
Пример 2. 200 г антрацена нагреваютс в тех же услови х с катализатором , состо щим из того же молибдата с СаНРО4 в отношении 1 :2. В продукте реакции 30% фракций низших ароматических углеводородов (бензол, толуол, ксилол), 60% жидких гидрюров нафталина и антрацена.Example 2. 200 g of anthracene are heated under the same conditions with a catalyst consisting of the same molybdate with СНРО4 in the ratio 1: 2. In the reaction product there are 30% of fractions of lower aromatic hydrocarbons (benzene, toluene, xylene), 60% of liquid naphthalene and anthracene hydrouses.
Пример 3. При опускании смеси паров нафталина и его гидрюров с водородом в отношении 1:10 (в мол х) под рабочим давлением в 200 атм. при температуре 523 под контактной массой, приготовленной нанесением одного из вышеупом нутых катализаторов на каолин в течение 5-10 секунд около половины исходного продукта превращаетс в углеводороды, состо щие почти из одних ароматических углеводородов.Example 3. When lowering the vapor mixture of naphthalene and its hydruriums with hydrogen in the ratio of 1:10 (in moles) under a working pressure of 200 atm. at a temperature of 523, under the contact mass prepared by applying one of the above-mentioned catalysts to kaolin for 5-10 seconds, about half of the original product is converted into hydrocarbons consisting almost of aromatic hydrocarbons alone.
Предмет изобретени .The subject matter of the invention.
Способ гидрировани нафталина, антрацена и других ароматических углеводородов при повышенной температуре и давлении в присутствии фосфорномолибденово-аммониевой соли и солей фосфорной кислоты, отличающийс The method of hydrogenation of naphthalene, anthracene and other aromatic hydrocarbons at elevated temperature and pressure in the presence of phosphomolybolybdenum-ammonium salt and phosphoric acid salts, different
тем, что гидрирование ведут в две стадии: сначала при более низкой температуре и давлении, а затем температуру и давление значительно повышают.the fact that the hydrogenation is carried out in two stages: first, at a lower temperature and pressure, and then the temperature and pressure are significantly increased.
