1. Sulphuric acid and ammonium sulphate solutions were electrolysed in order to see the influences of the current density and OH′-concentration. 2. Influence of various cations, H., K., NH4., Na., Li.., Mg.., Zn..., FE..., Al..., Cu.., and Cd.., was studied and some were explained to have connexion with persulphate formation. 3. A new suggestion was made that OH′ plays an important rôle in persulphate formation, and this suggestion will clearly explain the results of the present investigation which may otherwise be obscure.
The synthesis of an eleven-membered carbon ring attached to the ortho-position of benzene was attempted. The dry distillation of the thorium salt of o-phenylene-divaleric acid resulted in the formation of a twenty-two-membered diketone ring. Several new compounds incidental to the synthesis are reported.
A decenoic acid has been separated from sperm head oil. Its methyl ester was oxidised with potassium permanganate in acetone, and after the saponification of the acid ester contained in the oxidation products, azelaic acid was identified. The presence of formic acid in the oxidation products was also indicated. Accordingly the decenoic acid in sperm head oil is proved to be Δ9:10-decenoic acid, having the formula CH2=CH·(CH2)7·COOH.
The high boiling fraction of the unsaponifiable matter of sperm blubber oil was brominated in ethereal solution, and the ether insoluble bromide was separated and then debrominated to regenerate the highly unsaturated alcohols. These were converted into acetates, and the latter were fractionated. An examination of the resulting fractions showed that the highly unsaturated alcohols of sperm blubber oil contained two individual alcohols C20H34O and C22H36O as chief components.
