摘要:
A process for purification of vinylaromatic monomers or cyclic aliphatic monomers containing contaminating quantities of indene and/or phenylacetylene comprising contacting the impure monomer with a dialkylmagnesium compound containing from 1 to 10 carbons in each alkyl group, removing reaction byproducts and recovering the purified monomer.
摘要:
C₂-C₆ aliphatic hydrocaroons are converted into easily transportable hydrocaroons of greater molecular weight by a combination process which comprises converting the C₂-C₆ aliphatic hydrocarbons to aromatic hydrocarbons in a dehydrocyclodimerization reaction zone after which this aromatic product is directly hydrogenated in the presence of hydrogen, preferably from the dehydrocyclodimerization reaction step, to produce a naphthene-rich product stream. It is also an aspect of the invention that the hot hydrogenation reaction zone product stream is used to preheat the feed stream to the dehydrocyclodimerization reaction zone.
