  • Formation of palladium hydride and carbide phases in palladium-based catalysts is a critical process which changes the catalytic performance and selectivity of the catalysts in important industrial reactions, such as selective hydrogenation of alkynes or alkadienes. (rsc.org)
  • Straight chain alkenes, alkadienes and alkatrienes from 23-44 C atoms were partially characterized. (eurekamag.com)
  • Among the unsaturated cuticular hydrocarbons characteristic of queens, there were differences in amounts of alkenes/alkadienes between non-reproductive polygyne queens of different Gp-9 genotypes, between non-reproductive and reproductive queens, and between polygyne and monogyne reproductive queens, with the amounts increasing at a relatively higher rate through reproductive ontogeny in queens bearing the Gp-9 b allele. (eurekamag.com)
  • The cuticle of physogastric queens presented a chemical profile that was distinct from all other groups in the analysis, with high relative abundances of alkenes and alkadienes with 27, 29, and 31 carbon atoms. (nih.gov)
  • Their functional isomers are alkadienes and cyclo alkenes. (studymode.com)
  • Thirty-six CHC components were scored in single fly extracts with carbon chain lengths ranging from C 29 to C 39 , including methyl-branched alkanes, n -alkenes, and alkadienes. (biomedcentral.com)
  • Pyrolyzates of Botryococcus-related alginites are characterized by an abundance of normal alkadienes, alkenes, and alkanes. (montclair.edu)
  • Eg: Alkenes, alkadienes and their derivatives. (myrank.co.in)
  • Alkenes were the least prevalent, with alkadienes dominating the chromatographic landscape in the longer chain lengths. (storysteel.ml)
  • Nomenclature Alkenes with more than one double bond are called alkadienes (2 double bonds) alkatrienes (3 double bonds) etc… Each double bond is designated by its lower-numbered carbon. (slidegur.com)
