Millimeterwave Spectrum and Dipole Moment in the ν5, ν6, and ν9Excited States of Ketene: Comparison toab InitioResults for Ketene and Ketene-d2

“…ress, as evidenced, e.g., by the recent publications of Johns Ketene has been obtained by gas-phase pyrolysis of aceet al (5) on the ground state rotational spectrum and by the tone in a quartz tube at 800ЊC (11,12), using helium as a ab initio work of East et al (6). A short review on the carrier gas.…”

A simple ketene generator.

“…OTHER REACTIONS Instead of using aniline as the reactant, ketene may also be allowed to pass through an excess of standard NaOH solution and the excess of the alkali back titrated with standard acid. Other reactions of ketene which may be similarly carried out are tested in Table Thioacetie anhydride (8) Ethyl methyl ketone Ethyl thioacetate (10) n-Acetyl-j3-naplithylamine (6) LITERATURE CITED…”
