Oxidation of Alcohols

Oxidizing reagents Details Sodium dichromate Na 2 Cr 2 O 7 in aqueous H 2 SO 4 (Jones reagent): Oxidizes alcohol to aldehyde The problem of further oxidation to carboxylic acid caused by the presence of water can be avoided for volatile alcohols in most cases by distilling the alcohols from the reaction mixture Very often it is more favorable to use acetic acid instead of sulfuric acid

WLD 210 TP

The metallurgical reason for the zinc oxide layer is to protect the zinc from volatilizing out of the molten weld pool This is because most brasses are composed of copper and from about 5% to 40% zinc Because zinc has a low melting point of only 420C (787F) while copper has a high melting point of 1083C (1981F) zinc in the molten weld pool tends to boil and vaporize This
