Phosphotungstic acid is applied as a homogeneous catalyst for oxidative cleavage of methyl 9,10-dihydroxystearate, allowing retention the via organic solvent nanofiltration.

Nuclear Lamina, Insect, Fat Body, Phosphotungstic Acid, Protein Staining The nuclear envelope of the larval fat body in the blow­ fly Calliphora vicina reveals a conspicuous nuclear lamina. It appears homogeneous, Fibrous or granular depending upon the fixing and staining methods. The best relative contrast for the nuclear lamina and the nuclear pore com­ plex is obtained with a phosphotungstic...

Production of 5-hydroxymethylfurfural (HMF) from biomass-derived glucose has great potential for synthesis renewable fuels and chemicals. Selective conversion to requires a balance between Lewis Brønsted acids the cascade isomerization followed by fructose dehydration. A dual Brønsted-Lewis acid, phosphotungstic acid encapsulated MIL-101(Al)–NH2 metal–organic frameworks (MOFs) was developed cat...

a simple and efficient one-pot, three-component strecker reaction of protected amino acids, aromatic aldehydes, and trimethylsilyl cyanide has been developed for the synthesis of chiral α-amino nitriles. the reaction was carried out in the presence of catalytic amount of phosphotungstic acid (h3[p(w3o10)4]) as an environmentally friendly catalyst.

Uric acid is commonly determined in biological fluids by measuring the blue colour produced by its reaction with reagents containing phosphotungstic or arsenotungstic acids under conditions which minimize interference by other reducing substances (Folin & Denis, 1912; Folin, 1933, 1934; Benedict, 1912, 1922; Brown, 1945; Bidmead, 1951). Recovery of uric acid added to blood has never been comple...
