Acid anhydride reactions

In the case of acids and acid anhydrides, reaction can also occur via the hydroxyl groups that are present, including those formed on opening of the epoxide ring. [Pg.753]

It is advisable that the epoxide resin/hardener component has high Tg. A crosslinked IPN was obtained e.g. from epoxynovolak resin, pyromellitic dianhydride, triethanolamine (epoxide — acid anhydride reaction catalyst), BPA/DC and Zn acetate (cyclo-trimerization catalyst) [78],... [Pg.52]

In this type of protein immobilization, reactions involve the acylation of an NH2 group on a protein or an enzyme by pendent groups of the carrier such as azide, acid anhydride, carbodiimide, sulfonyl chloride, and hydroxysuccinimide esters. Copolymers of acrylamide and maleic anhydride have been useful for enzyme immobilization through the acid anhydride reaction with the enzyme. This system of... [Pg.1929]

The azlactones behave in many respects like acid anhydrides and react with a wide variety of compounds, such as water, alcohols, amines, and hydrogen halides, which contain active hydrogen atoms. As with acid anhydrides, reaction occurs most readily with amines, less readily with alcohols, and least readily with water. [Pg.213]
