Assignment of configurations of conjugated dienic pheromones by fuzzy classification of carbon-13 chemical shifts was written by Zhang, Youjie;Huang, Wenfang;Zhu, Jun. And the article was included in Analytica Chimica Acta in 1990.Safety of (E)-Dodeca-9,11-dien-1-yl acetate The following contents are mentioned in the article:
The configurations of conjugated dienes, and some sex pheromones and analogous compounds, can be characterized by a fuzzy classification method applied to the 13C chem. shifts of the dienic carbons. A fuzzy relation matrix of 12 model dienes is set up, and a fuzzy parameter (λ) is established. If λ â?.95 in the similarity test of two dienes, then both dienes have the same configuration. Some empirical rules dealing with the influence of terminal groups and assignment of the order of dienic carbons are presented. Configurations of 14 compounds prepared by different methods were established reliably. After correct assignments of dienic carbons, the method was used to quantify the isomeric composition of (10,12)-pentadecadienyl acetate, (9,11)-tridecadienyl acetate and (9,11)-tetradecadienyl acetate by the inverted gated decoupling technique; the results agreed well with those obtained by gas chromatog. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Safety 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. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Safety of (E)-Dodeca-9,11-dien-1-yl acetate
