摘要： A method for controlling the production of heavy compounds in the production of alpha-methyl styrene is provided. In one embodiment, the method includes providing a first composition to a distillation column, said first composition comprising acetone, phenol, cumene and alpha-methyl styrene; refining the first composition in the distillation column to produce a second composition comprising at least 1 wt. % alpha-methyl styrene and at least one organic acid, wherein the second composition includes a higher weight percentage of alpha-methyl styrene than the first composition; and adding an amine to the second composition.

摘要： The invention concerns substance mixtures containing: (A) monomers containing vinyl groups; and (B) an active amount of a mixture which inhibits premature polymerization of the monomers containing vinyl groups during their purification or distillation and contains: (i) between 0.05 and 4.5 wt %, relative to the total mixture (B), of at least one N-oxyl compound of a secondary amine which has no hydrogen atom at the α-C atoms; and (ii) between 99.95 and 95.5 wt %, relative to the total mixture (B), of at least one nitro compound. The invention further concerns a process for inhibiting the premature polymerization of monomers, and the use of mixture (B) for inhibiting the premature polymerization of monomers.

摘要： Process for the catalytic dehydrogenation of diethylbenzene or C3 alkyl aromatic in which a fecdstock containing the alkyl aromatic and steam is supplied into the inlet of a tubular reactor containing a dehydrogenation catalyst. Within the reactor, the feedstock flows through at least a portion of the reactor along a spiral flow path extending longitudinally of the reactor. The resulting vinyl aromatic product is then recovered from a downstream or outlet section of the reactor. At least a portion of the spiral flow path contains a particulate dehydrogenation catalyst. The spiral flow path may extend throughout a major portion of the elongated tubular reactor and may contain a particulate dehydrogenation catalyst in a substantial portion there.
