preparation example Construction
[0038] The invention provides a preparation method of an oil-soluble catalyst, the preparation method comprising the steps of:
[0039] Step 1, mix the amine compound and the sulfide, and react at 50-300°C for 1-3 hours, wherein the molar ratio of the amine compound to the sulfide is 1:10-9:1, preferably 1:2- 2:1;
[0040] Step 2, then adding the metal compound and reacting at 30-200°C for 1-3 hours; and
[0041] Step 3, cooling the product after the reaction in step 2, suction filtering, washing, and vacuum drying at 20-80°C to obtain an oil-soluble catalyst;
[0042] Wherein, the metal compound is one or more of the group consisting of iron-containing compounds, nickel-containing compounds, cobalt-containing compounds, molybdenum-containing compounds and tungsten-containing compounds.
[0043] The amine compounds used in the present invention are generally organic amines or their salts, preferably n-propylamine, isobutylamine, n-pentylamine, tri-n-octylamine, dodecyl-prima...
Embodiment 1
[0051] 1) Weigh 12.6g of n-pentylamine and add it to the flask, add sodium sulfide solution, wherein the molar ratio of n-pentylamine / sodium sulfide=9 / 1, react at a constant temperature for 2 hours at a reaction temperature of 90°C, and use electromagnetic stirring during the reaction After the reaction was completed, the temperature of the reaction was down to room temperature;
[0052] 2) Weigh molybdenum trioxide and add ammonia water to dissolve to obtain a solution, add the solution to the product obtained in step 1), the molar ratio of molybdenum trioxide / n-pentylamine=3 / 1, react at 60°C for 1h, and the obtained product is fully cooled Filter with suction, wash thoroughly, and vacuum-dry at 30°C to obtain an oil-soluble hydrogenation catalyst, code A-1.
