Gas-phase reactivity of acyclic α,β-unsaturated carbonyls towards ozone

“…The relative rate technique relies on the assumption that both target compound and reference are solely removed by the oxidant as follows carbonyl + O 3products; k carbonyl (1) reference + O 3products; k reference (2) However the unsaturated carbonyls are potentially subject of an irreversible first-order wall loss:…”

“…Esters like methyl methacrylate are important intermediates in the polymer industry. 1 Unsaturated ketones are mainly used in the food and fragrances industry. 2,3 4-Methyl-3-penten-2-one is also utilized for the production of methyl isobutyl ketone (MIBK), a common polar solvent with wide applications in the manufacturing of pharmaceuticals, paints and coatings.…”

Low-Dispersity Polymers in Ab Initio Emulsion Polymerization: Improved MacroRAFT Agent Performance in Heterogeneous Media

“…where [M]w is the saturated monomer concentration in water (for BMA, 7.0 mmol L -1 ). 53 Interval I was assumed to be completed at 10% conversion. [51][52] The beginning of Interval III was taken as the point when the monomer concentration based on Eq.…”

Herstellung von Grundchemikalien auf Basis nachwachsender Rohstoffe als Alternative zur Petrochemie?

“…In diesem Fall wird Ethylen zu Propanal hydroformyliert, im zweiten Schritt mit Formaldehyd zu Methacrolein kondensiert, das dann mittels katalytischer Oxidation das Endprodukt liefert [56].
