Determination of Dibasic Acids in Alkyd Resins

Abstract

the aliphatic anilides, the amides do not show any evidence of a zigzag structure when the longest spacings are plotted against the number of carbon atoms.

Review - Coatings

“…Chlorinated diphenyl affects neither the phthalic nor the vinyl determination. If potassium chloride is present, the phthalic content can be determined by the Swann lead precipitation procedure (34).…”

“…The quantitative isolation of aluminum from other elements in ferrous metals remains the principal obstacle to its accurate determination. Complexing or sequestering agents which have been investigated include: the sodium salt of ethylenediaminetetraacetic acid (EDTA) in the presence of potassium cyanide (14), thioglycolic acid (34), ascorbic acid following a mercury…”

Determination of Nitrogen in Nitrocellulose and of Nitrocellulose and Combined Phthalate in Lacquers

“…of 1 .V titanous chloride). method of Kappelmeier (2, 9), the volumetric potassium phthalate method of Goldberg (8), the lead phthalate method of Swann (15), or the spectrophotometric method of Shreve and Heether ( 14)-However, when present in a lacquer containing an alkyd resin, nitrocellulose interferes. Unfortunately, the alkyd resin cannot be separated quantitatively from the nitrocellulose by any solvent precipitation method.…”

New Method for Determining Phthalate Esters in Propellants

“…DURING the past 10 years several papers have been published dealing with the determination of phthalates. Their authors suggested polarographic (14), spectrometric (9), volumetric (2), or gravimetric methods (8,11).…”
