چکیده انگلیسی

The conversion of triglycerides (coffee oil) obtained from spent coffee ground to produce hydrocarbon fuel (diesel) was studied. In more detail, a catalytic hydrodeoxygenation of the coffee oil was performed applying polymethylhydrosiloxane (PMHS) as cheap reductant under mild reaction conditions. However, along with the hydrocarbons significant amounts of PMHS-waste are generated, since only ∼1.7% of the PMHS is required for the reduction process. Based on that, in a subsequent depolymerization step the PMHS-waste was converted to methyltrifluorosilane and difluoromethylsilane, which can be applied as building blocks for the production of new silicones, with boron trifluoride diethyl etherate (BF3OEt2) as depolymerization reagent.
