Abstract
Publisher Summary This chapter discusses the methods of preparation of hydroxamic acids. It describes the condensation reactions for the preparation of benzohydroxamic acid in pyridine and the preparation of poly (hydroxamic acids). Polyacrylonitrile can be reacted with hydroxylamines to form a polyamidoxime that on hydrolysis gives a polymeric hydroxamic acid. The general procedure of reacting aliphatic esters with hydroxylamine does not lend itself well to the preparation of large quantities. The chapter discusses severe explosions that take place with reactions in which hydroxylamine or its common salts are used. Explosions with pure hydroxylamine hydrochloride and with hydroxylamine sulfate are noted on heating these reagents. Hydroxylamine and its salts should never be exposed to elevated temperatures. The chapter also presents the hazards and safe handling practices for hydroxamic acids.
