ISOMERIZATION OF OLEFIN
PURPOSE:To carry out isomerization of an olefin, by changing the position of double bond of an olefin using a catalyst consisting of an organic aluminum compound and a fluorinated isopropanol. CONSTITUTION:The position isomerization of the double bond of an olefin is carried out by using an organic...

CONSTITUTION:The position isomerization of the double bond of an olefin is carried out by using an organic aluminum compound of formula I (R is lower alkyl) (e.g., trimethylalumium) and a fluorinated isopropanol of formula II (4<=m-n<=6) at a molar ratio of 1:(0.5-5). The isomerization is carried out preferably using an aliphatic hydrocarbon, aromatic hydrocarbon or their halide as a solvent. The amount of the catalyst is 10<-5>-10<-2>mol of organic aluminum per 1mol of the olefin used as a raw material and the reaction is performed at 10-100 deg.C. EFFECT:The objective compound can be produced in high isomerization ratio with small amount of catalyst giving little by-product.</description><language>eng</language><subject>ACYCLIC OR CARBOCYCLIC COMPOUNDS ; APPARATUS THEREFOR ; CHEMICAL OR PHYSICAL PROCESSES, e.g. CATALYSIS OR COLLOIDCHEMISTRY ; CHEMISTRY ; GENERAL METHODS OF ORGANIC CHEMISTRY ; METALLURGY ; ORGANIC CHEMISTRY ; PERFORMING OPERATIONS ; PHYSICAL OR CHEMICAL PROCESSES OR APPARATUS IN GENERAL ; THEIR RELEVANT APPARATUS ; TRANSPORTING</subject><creationdate>1987</creationdate><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=19870914&DB=EPODOC&CC=JP&NR=S62209028A$$EHTML$$P50$$Gepo$$Hfree_for_read</linktohtml><link.rule.ids>230,308,776,881,25542,76290</link.rule.ids><linktorsrc>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=19870914&DB=EPODOC&CC=JP&NR=S62209028A$$EView_record_in_European_Patent_Office$$FView_record_in_$$GEuropean_Patent_Office$$Hfree_for_read</linktorsrc></links><search><creatorcontrib>SATO HIROSHI</creatorcontrib><creatorcontrib>IKIMI KIYOSHI</creatorcontrib><creatorcontrib>TOSHIMA HIDETO</creatorcontrib><title>ISOMERIZATION OF OLEFIN</title><description>PURPOSE:To carry out isomerization of an olefin, by changing the position of double bond of an olefin using a catalyst consisting of an organic aluminum compound and a fluorinated isopropanol.
