A fuzzy classification for identification of double bond position in dodecadienic compounds based on mass spectral data was written by Gu, Yuan. And the article was included in Organic Mass Spectrometry in 1988.Quality Control of (E)-Dodeca-9,11-dien-1-yl acetate The following contents are mentioned in the article:
A fuzzy classification and a computer pattern recognition program are presented for identifying double bond positional isomers of dodecadiene compounds by comprehensively analyzing the mass spectra and calculating similarity coefficients of the compounds Fifty-four examples showed that this is an excellent classification method. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Quality Control of (E)-Dodeca-9,11-dien-1-yl acetate).
(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
