CCXCIX.—Chlorination of benzoyl chloride. Part I

3-benzoyl derivative (IIa) could be directly prepared from (I) using an equivalent mole of benzoyl chloride in the presence of an excess of aluminum chloride in nitrobenzene

compound possessing the acyl group in the 3-position of DHA nucleus 〔triacetic acid lactone (TAL)〕, the derivatives having the aroyl instead of the acyl group in the 3-position have never been synthesized. In order to investigate the activity which the carbonyl group in their side chain displays for of various primary amines and their antibacterial activity, some new DHA type derivatives posses...

N-Benzoyl-N′,N′′-diphenyl­guanidinium chloride

In the title compound, C(20)H(18)N(3)O(+)·Cl(-), the orientation of the aromatic rings around the planar CN(3) (+) unit produces steric hindrance. As a consequence of this particular orientation of the guanidinium cation, hydrogen bonding is restricted to N-H⋯Cl and intra-molecular N-H⋯O hydrogen bonds within the discrete unit. The guanidinium and carbonyl groups are coplanar as a result of the...

Electrodeposition of Zinc From Low Temperature Molten Salt Electrolyte: Part I-Imidazole And Zinc-Chloride Electrolyte

Our R & D work was focused on the electro deposition of Zinc from imidazole as low temperature molten salt (LTMS) electrolyte with zinc chloride as a supporting salt at <100o C., without required controls from the previous existing non aqueous baths as well additive free system for the zinc deposition. Surface morphological studies and crystallographic orientation results were evaluated.

The electrical conductivity and chloride content of women's milk. Part I: Methods and practical application.

Few observations have been recorded on the electrical conductivity of women's milk. Koeppe (1898) measured the conductivity of 19 specimens of milk taken from five women who were in various stages of lactation. The values of specimens taken in thefirstmonthranged from 174 to 454 10-a ohm-' cm.-' and those taken during the second to eleventh months varied from 150 to 238 X 10-5ohm-' cm.. In the ...
