Chemical syntheses in electric discharge
Several types of radio-frequency, induction-coupled plasma torches have been used for studying gaseous and gas-solid reactions at high temperatures. After a detailed examination of the various parameters which affect the ...
Ionization and dissociation studies of propadiene, 1, 3-butadiene, 1,3 trans-pentadiene, 2,4-hexadiene and 2,5-dimethyl-2,4-hexadiene by electron impact
The ionization and dissociation of propadiene, 1,3-butadiene, 1,3-trans-pentadiene, 2,4-hexadiene and 2,5-dimethy1-2,4-hexadiene have been studied using a CEC-21-701 mass spectrometer. The ionization potentials measured ...
Preliminary studies in the total synthesis of verrucarol
A preliminary investigation was undertaken to find a route to the cis A-B ring fusion of the sesquiterpene alcohol verrucarol. To synthesize the desired cis-lactone (47), methylacetoacetate (60) was alkylated with ...
The fine structure of cupric ferrocyanide semipermeable membranes
Electron microscopic and electron diffraction studies have been carried out on cupric ferrocyanide gels, chosen as a prototype of an inorganic semi-permeable membrane. It was believed that a study of the structure and ...
