The Raman spectra of I2, Br2, and ICl have been studied in various solutions in the region below 400 cm.-1 by means of a Raman spectrophotometer equipped with a 50 mw. He-Ne laser. Quite satisfactory Raman spectra of these colored solutions were obtained, but for some Br and ICl complexes chem. reactions occurred. The observed Raman frequencies for the halogens or the interhalogen were considerably lower than the corresponding gas values, and the data have been interpreted on the basis of charge-transfer interaction. Some very strong donor-halogen interactions were observed, in which the stretching force constant of the halogens was reduced to approx. half the gas value. A Raman band at 163 cm.-1 in the pyridineiodine system was interpreted as the N-I stretching mode; otherwise no Raman bands were observed which can with certainty be assigned to the stretching of the donor-halogen charge-transfer bond. 36 references.

Distribution coefficients (P) of RC₆H₄CONHNH₂ (I; R = H, p-Me, m-Me, m-NH₂, o-OH, m-Cl, etc.) were determined in the octanol-water system via UV spectral data; Hansch π-substituent constants were calculated from P. Linear correlations of log P for the p– and m– substituted I with π values for the corresponding RC₆H₄CONH₂ and RC₆H₄OCH₂CO₂H were given. An observed ortho effect in I was ascribed to intramol. H bonding.

Anal. of I-containing (50-69% of I) pharmaceutical preparations by combustion in O utilizes a new modification of the method and a comparison is made with the existing ones. The sample (0.02-0.03 g.) is placed on the Pt grid (initially not in contact with the solution), 10 ml. 2N KOH and 50 ml. H2O are poured into a flask and O bubbled through 5 min. Then the sample is burned (20-30 sec.) and the flask tightly stopped. The content is then shaken (5-6 min.) and allowed to stand for 10 min. more. Br (5 ml.) and AcOH are then added, the solution stirred and 0.3 ml. 85% HCO2H added. After the solution has lost its color, 20 ml. of N H2SO4 and 0.05 g.

A wide range of aromatic compounds (e.g., C₆H₆) have been effectively iodinated with a pyridine-iodine monochloride complex (I). Condensed polycyclic iodides, which are not readily obtained via direct iodination, can be prepared indirectly via their corresponding organomercurials in 1 step. Some benzoid and nonbenzoid heterocycles (e.g., indole) are iodinated with I.

Chem. substances (20) were tested for inhibition of growth of Clostridium perfringens types C and D. Spore suspensions containing a billion cells/cc. were used as test objects. Sterile cloth (0.5 cm. × 0.5 cm.) was soaked in the resp. spore suspension, dried, exposed to 3 cc. of solution and tested for viability. All solutions containing Cl demonstrated a bactericidal action, increasing with temperature The most effective are: acidified bleaching powder and monochloroiodine compounds Acids and alkali solutions are ineffective at low temperature, but strongly inhibitory at 60°. The bactericidal effect of the following substances is enhanced by a combined treatment at different temperatures: solutions of bleaching powder, acidified bleaching powder, monochloroiodines, pyridine iodochlorideHCl, and of OH with etherane 138 (a crude-oil product). The spores of C. Perfringens type D are more resistant than those of type C.

Sheka, I. A. published the artcileThe application of dielectric polarization for the determination of the composition of complex compounds in solutions, SDS of cas: 6443-90-9, the publication is Izvest. Sektora Platiny i Drug, Blagorod. Metal., Akad. Nauk S.S.S.R., Inst. Obshcheǐ i Neorg. Khim. (1951), 189-202, database is CAplus.

It has been known for some time that the dielec. polarization P for complexes is more than the simple sum of the compounding mols. By comparing numerous reliable data from the literature, it was noted that not only ΔP will accept a rather large value for the case of complex formation, but Δε also, which is understandable, as ε (dielec. constant) appears in the formula for P. By plotting curves ΔP vs. composition and Δε vs. composition, a maximum in such curves will indicate the formation of a complex. For allyl isothiocyanate and piperidine in benzene these 2 maximum coincided with those for viscosity, deviation of the sp. volume, heat of mixing, n, and the temperature coefficient of the viscosity. For pyridine and ICl in CHCl₃ the ΔP and Δε maximum coincided with one of the m.p. maximum in the m.p. diagram of pyridine ICl. Thus the plotting of the ΔP-composition and Δε-composition diagrams may serve to replace other very tedious determinations of other physicochem. values which have been used heretofore to find out the presence or absence of complexes. The maximum in these curves will not occur if merely van der Waals forces are acting. If more than one complex is formed, only one will give rise to a maximum; the other will be indicated by a break in the curve. Thus for the case AlBr₃-dioxane the break is found for (AlBr₃)₂.C₄H₈O₂, whereas the maximum lies at AlBr₃.C₄H₈O₂. The higher the maximum in these curves, the more stable the complexes.

The dielec. properties of ICl systems with dioxane, pyridine, and quinoline, and of IBr with dioxane, CHCl₃, and CCl₄ as solvents were investigated. The maximum deviations of the dielec. constants and polarization from the calculated values corresponds to the formation of definite complex compounds in solution In the ICl-C₅H₅N and ICl-quinoline systems in CHCl₃, solution, the maximum deviations of ΔAP and Δε are very sharp, and their values exceed by many times the deviations in the systems of IBr and ICl with dioxane and CCl₄. A comparison of the values of the polarization deviations and the instability constants of C₄H₈O₂.ICl and C₄H₈O₂. IBr shows that the systems formed in ICI and IBr by dioxane must be considered irrational, while ICl forms with pyridine and quinoline rational systems. With ICl quinoline forms 2 compounds: C₉H₇N.ICl and C₉H₇N.2ICl; the second is more stable in CHCl₄ solution than is the analogous compound with pyridine.
