Anhydrous Formic Acid

Conductances of some 1 : 1 electrolytes have been measured in the concentration range (5-100) x 10-3 mol l-1 in anhydrous formic acid at 25�. The conductance data have been analysed by Fuoss-Shedlovsky equations. Transference numbers of sodium and potassium formates have been measured in this solvent at 25� by a modified Hittorf's method in the concentration range (3-80) x mol l-1. Ionic mobilities, effective ionic radii and solvation numbers of various ions in solution have been calculated. Solvation of cations decreases with the increase in the crystal radii of the ions.

Abstract Chromium(III) Chloride, Basic Chromium(III) Formate, IR, Thermogravimetry, Magnetic Moment Chromium(III) chloride reacts with anhydrous formic acid to give basic chromium(III) formate [Cr3O(OOCH)6(H2O)2(HCOOH)](OOCH), HCOOH. Its reactions with bases (B) give compounds of the general composition [Cr30(C00CH)6(B)3](00CH). The title compound has been characterized by infrared spectral data, temperature range (266-110K) magnetic moment and thermogravimetry.

Treatment of ATP:creatine phosphotransferase with anhydrous sulphuric acid permits transposition of 24% of the threonine residues and 69% of the serine residues. Treatment with anhydrous phosphoric acid yields similar results: 41% of the threonine residues and 60% of the serine residues are rearranged. Anhydrous formic acid does not induce an N- to O-acyl migration in the protein.Non-specific hydrolysis of peptide bonds or destruction of certain amino acids that might have occurred simultaneously with rearrangement during the anhydrous sulphuric or anhydrous phosphoric acid appears to be very slight. When the protein is treated with anhydrous sulphuric acid, however, phenylalanine "disappears" almost completely from the chromatogram.
