摘要:Our invention relates to catalysts and their use in the synthesis and conversion of alpha-olefin-containing products, essentially alpha-olefins, primarily from paraffins of renewable origin, having a carbon number of 11-45, and mixtures thereof, which mixtures contain paraffins having a carbon number of 11-45. The main steps of the process are the heterogeneous catalytic dehydrogenation of paraffin with a new zeolite-supported catalyst based on Pt, Pd or Ni, and then the conversion of the resulting olefin-containing product mixture, containing mainly straight-chain internal monoolefins, to lower homologous alpha-olefins—namely, the homogeneous or heterogeneous catalytic ethenolysis by using a ruthenium complex metathesis catalyst (i.e., metathesis using excess ethylene or ethylene metathesis), and/or tandem isomerization and metathesis reactions by using homogeneous or heterogenized homogeneous ruthenium complex metathesis catalyst in combination with a homogeneous or heterogeneous olefin isomerization catalyst (i.e., isomerization metathesis, hereinafter referred to as ISOMET), and/or tandem isomerization and ethylene metathesis by using a homogeneous or heterogenized homogeneous ruthenium complex metathesis catalyst in combination with homogeneous or heterogeneous olefin isomerization catalyst (i.e., isomerization ethylene metathesis, hereinafter referred to as ethylene ISOMET).

摘要:In order to provide low-odor polyurethane systems, in particular foams, an additive that is rich in odoriferous substances is used during synthesis of polyurethane systems, at least 5 wt% of the odiferous substances used having a ClogP value > 4 and a boiling point > 275°C.
