The Conversion Kinetics of Tincal to Boric Acid in Nitric Acid Solutions

Pure borax and various boron compounds are produced from the solutions in which tincal is dissolved with various reagents. Economically important boron compounds such as boric acid, borax, boric oxide, and refined hydrated sodium borates and perborates are produced from boron-containing ores. The production of boric acid by using nitric acid from tincal is more advantageous because it evalu...

Conversion of oleic acid to linoleic acid.

Reports from this laboratory have described the formation of palmitoleic and oleic acids from their saturated counterparts by enzyme systems of yeast (2, 3). For introducing a double bond into the 9,lO position of the aliphatic chain, the desaturating enzymes, acting on the coenzyme A derivatives of the fatty acids, require reduced triphosphopyridine nucleotide, and molecular oxygen as hydrogen...
