The paper chromatography of esters of phosphoric and phosphorous acids
Journal of Chromatography A, 1963Abstract Procedures are described for the separation on paper of the components of technical samples of alkyl and alkyl-aryl phosphites and of esters of phosporic acid. Suitable stationary and mobile phases, as well as spray reagents, are noted, and typical R F values are presented.

Phosphorous Acid and Arsenious Acid as Ligands
Inorganic Chemistry, 2001Complexes with P(OH)3 and As(OH)3 ligands coordinated to the Pd site of a heterometal cuboidal cluster cation with the Mo3PdS44+ core were obtained for the first time.

Acid Débridement of Burns with Phosphoric-Acid Gel
New England Journal of Medicine, 1951THE introduction of a satisfactory chemical method for the early debridement of burns would simplify a perplexing problem. For many years attempts have been made to find some agent that would selectively digest or remove the necrotic slough that follows severe burning. Since Connor and Harvey1 in 1944 first reported the use of pyruvic-acid starch paste

Pulpal response to phosphoric acid
Journal of Oral Pathology & Medicine, 1974Abstract. The chemical treatment of tooth surfaces to improve bonding of dental materials to enamel and dentin is one of the approaches in overcoming the lack of adhesion of the available restorative materials to tooth structure. The acid etch technique is now an accepted procedure in restorative and preventive dentistry and for the direct bonding of ...

New Synthesis of Phosphorous and Phosphoric Acid Esters
Synthesis, 1991Reaction of alcohols with dialkyl phosphites in the presence of titanium tetraalkoxides results in a displacement of both or one ester function(s) by the RO groups of the alcohol used. The mixed phosphites, (R 3 O)(R 1 O)P(O)H, prepared by this method can be used as substrates for the mixed phosphates, (R 4 O)(R 3 O)(R 1 O ...

Feulgen Hydrolysis with Phosphoric Acid
Stain Technology, 1953Sections from rat tissues fixed in a 10% solution of formalin in 90% alcohol were treated with phosphoric acid in concentrations varying from 30 to 85% at room temperature (28°), and subsequently stained with the Schiff reagent. Intense staining of the nuclear material was obtained in 5 to 15 minutes when 40 to 75% phosphoric acid was used. The intense

Synthetic Communications, 1971
Abstract Pyrophosphoric acid was first reported as a phosphorylating agent for highmolecular weight alcohols in 19341. Direct phosphorylating of sugars and sugar derivatives was first carried out by Cherbuliez2 who used polyphosphoric acid on alcohols, amines and glycols.
