Purification of Laboratory Chemicals, Eighth Edition, tabulates methods taken from literature for purifying thousands of individual commercially available chemicals. To help in applying this information, the more common processes currently used for purification in chemical laboratories and new methods are discussed. For dealing with substances not separately listed, a chapter is included setting out the usual methods for purifying specific classes of compounds. Features empirical formulae inserted for every entry References all important applications of each substance Updates and confirms the accuracy of all CAS registry numbers, molecular weights, original reference, and physical data Provides increased coverage of the latest commercial chemical products, including pharmaceutical chemicals, updated safety and hazard material, and expanded coverage of laboratory and work practices and purification methods
