Example 1B
To prepare a catalyst with a 3% platinum load according to the invention, a catalyst was first prepared in accordance with part A and then sulphidized with dimethyl sulphoxide in accordance with example 1 in DE-PS 21 50 220. The total sulphur content of the sulphidized catalyst was about 0.4 moles of S per mole of Pt.
Do I have too calculate how much DMsulphoxide or must I just follow this example.
EXAMPLE 1
100 grams of platinum-activated carbon catalyst (F 103 R of Degussa) having a platinum content of 1% were suspended in 400 ml of water and heated to 60.degree.C. After addition of 1 gram of dimethyl sulfoxide the mixture was stirred further for 15 minutes at 60.degree.C. The catalyst was then filtered with suction and washed. It can be added in the wet condition.
100 grams of Pt+H2O2/C (without sulphidizing)
contains 3% Platinum load. That's 3 gram Platinum. That's 0,015 mole. Every mole Pt must have 0,4 mole of S. That's 0,006 mole of S. That's o,19 grams of S. Molar mass of DMSO is 78.1288 That of S is 32.066 So S is 41,04% S present in DMSO. So if there is 0.19 grams of S in DMSO Then there is 0,46 grams of DMSO needed for this reaction. Am I right?????? ::)
