The hetero-association of acetic acid and trichloroacetic acid in CCl4 has been investigated using near infra-red spectra. Equilibrium constants and the enthalpy change have been calculated for the homo- and hetero-dimerization reactions over the temperature range 15°–40°. Results indicate that ...
The vapor association of acetic acid and propionic acid due to dimerization and trimerization has been considered as well.考虑乙酸与丙酸于气相因结合作用在气相形成二聚体及三聚体。 Different types of events may be responsible for the constitutive dimerization and activation in different growth factor rec...

The Dimerization of Ethylene Using Palladous Chloride as the Catalyst The dimerization of ethylene was carried out using palladous chloride as the catalyst. Acetic acid, ethylene dichloride, ethylene tetrachloride, benzene, chlorobenzene, triethyleneglycol, acetic acid esters, chloroform, cyclohexane and ...
The following are prepared in the examples: (1) disodiooctadienes and sebacic acid, 2-ethyl suberic acid, 3-ethyl suberic acid and 2,5-diethyl adipic acid; (2) decadienediols; (4) benzyl sodium (by transmetalation with toluene) and phenyl acetic acid; (7) C12 dicarboxylic acids; ...
Thioacetic Acid/NaSH-Mediated Synthesis of N -Protected Amino Thioacids and Their Utility in Peptide Synthesis of N-protected amino thioacids from the corresponding N-protected amino acids, oxidative dimerization of thioacids, crystal conformations of thioacid oxidative dimers, and the utility of thio...
Selective dimerization of arylalkynes to (E)-1,4-diaryl enynes catalyzed by the [Ru(p-cymene)Cl 2 ] 2 /acetic acid system under phosphine-free conditions. Bassetti, Mauro,Pasquini, Chiara,Raneri, Antonino,Rosato, Deborah. Journal of Organic Chemistry . 2007...
In another recent study, Li and co-workers used a catalytic system containing ZnCl2 and trichloacetic acid and showed that the combination of Lewis and Brønsted acid is required for the dimerization of levulinic acid to give two C10 compounds [12]. We have been working on catalytic ...
Process for the reduction of the polymer portion in the dimerization of ketene The polymer portion in the production of diketene by the dimerization of ketene obtained from acetic acid by pyrolysis is reduced by the addition of sulfur dioxide to the ketene gas or to the reaction medium. R Berg...
Further, in Japanese Patent Laying Open No. 105602/75, a process for the oxidative dimerization of propylene, toluene, acetic acid or other compounds by the reaction with bismuth oxide or thallium oxide has been disclosed, and it has proposed that the catalytic activity of bismuth oxide or thal...
