Abstract

1,168,940. Co-dimerizing propylene and nbutylene. ESSO RESEARCH & ENG. CO. 11 July, 1968 [17 Aug., 1967 (2); 16 Nov., 1967], No. 33114/68. Heading C5E. Propylene and n-butylene are copolymerized to give high yields of straight chain and singlybranched chain C 6, C, and C 8 olefins, by contacting propylene and n-butylene in a feed ratio of 1 : 1 to 1 : 5 in the presence of a supported NiO catalyst at 140-300‹ F. and at sufficient pressure to provide a liquid phase reaction, e.g. 150-1000 p.s.i.g. The C 8 and higher olefins may be separated from the reaction product and contacted with further propylene in a second zone, in the vapour phase and in the presence of a supported, partially dehydrated H 3 PO 4 catalyst at 280-550‹ F. where the C 8 olefins are converted back to isobutylene (present in the initial feedstock) which reacts with the additional propylene to give heptenes. Mixed C 3 -C 4 feedstocks containing acetylenes and diolefins as impurities may be used in which case the addition of 1-10 moles of H 2 to the stream per mole of impurity suppresses catalyst poisoning. Data are given for the addition of H 2 to butene feedstocks containing butadiene impurity which are polymerized to dimers and trimers.
