4-hydroxy-3-hexanone catalytic dehydration method

The invention relates to a 4-hydroxyl-3-hexanone catalytic dehydration method and mainly aims to solve the problems of a catalyst in the prior art, such as low activity, high reaction temperature and low space velocity. According to the technical scheme, 4-hydroxyl-3-hexanone serving as a raw material comes into contact with a catalyst to generate 4-hexylene-3-hexanone under the conditions that the reaction temperature ranges from 200 DEG C to 400 DEG C and the liquid mass space velocity relative to the 4-hydroxyl-3-hexanone is equal to 0.5-15h, wherein the used catalyst has the crystal grain diameter being at most 5mm, and has ZSM-5 zeolite with mesopores and micropores, and the ratio of the volume of the mesopores to the volume of the micropores in the ZSM-5 zeolite is equal to 1.5-10. The problems in the prior art can be well solved by adoption of the technical scheme. The 4-hydroxyl-3-hexanone catalytic dehydration method can be used for industrial production of 4-hexylene-3-hexanone prepared by using the 4-hydroxyl-3-hexanone.

COUPLING REACTION BETWEEN METHYLPROPIONATE AND METHANOL TO FORM METHYLMETHACRYLATE OVER METAL ION-CONTAINED MAGNESIUM OXIDE CATALYSTS

Solid-base catalyst, MgO modified by metal ion promoted the cross-coupling reaction between methylpropionate and methanol to give methylmethacrylate. 65percent selectivity to methylmethacrylate was attained by using 16.7 wtpercent Mn-MgO catalyst at 400 d

Rhodium-Catalyzed C,C-Double Bond Cleavage by Molecular Oxygen

Acetylacetonatorhodiumolefin systems, allylrhodium complexes, or (Ph3P)3RhCl catalyzed the conversion of alkenes and molecular oxygen to carbonyl compounds via C=C-bond cleavage.For example, 2,3-dimethyl-2-butene was transformed into acetone.Butadiene and isoprene also undergo oxidative C=C-bond cleavage to form acrylaldehyde and related compounds.

INSERTION D'ALLENES. VII. SYNTHESE DE COMPLEXES (η4-HETERODIENE)FER TRICARBONYL A PARTIR D'ALLENES

η4-Hydroxytrimethylenemethane-iron complexes are obtained by protonation of complex anions.They isomerise easily into a mixture of isomeric η4-heterodieneiron tricarbonyl complexes which have been separated.This demonstrates that such complexes are now available starting from allenes, alkyl halides and sodium tetracarbonyl ferrate.
