The amine containing side chain of lysine has been shown to undergo acylation reactions in the presence of anhydrides (Fig.
Epoxy resins cured by anhydrides usually have better properties than resins cured by amines.
They had a plant built at this complex to produce orthoxylenes, paraxylenes and pthalic anhydrides, with the paraxylenes converted into purified terephthalic acids (PTA) for use in polyester manufacture.
These results indicate that films cured with diamines or anhydrides are crosslinked to a high degree.
SIZING PERFORMANCE AND HYDROLYSIS RESISTANCE OF ALKYL OLEATE SUCCINIC ANHYDRIDES
Q: I recently learned about a commercially available product called alkenyl succinic anhydrides (ASA's).
The new bands corresponding to the cyclic anhydrides are clearly seen at 1867 and 1792 [cm.
In water solution anhydrides rapidly react with ammonia or primary or secondary amines to form a monoamide, monocarboxylic acid group, which is commonly referred to as an amic acid (see Figure 2).
Company offers amines and anhydrides as room-temperature, high-temperature and latent epoxy catalysts.
Other applications for MA include agricultural chemicals, malic acid, fumaric acid, lube oil additives, alkenyl succinic anhydrides, reactive plasticizers, sulfosuccinic acid esters, and a number of other chemicals.
Usually, amines or diacid anhydrides serve as hardeners, yielding mostly networks of alternating copolymers.
The hydrazide group reacts quickly at relatively low temperatures (140 F and above) with anhydrides, isocyanates, and epoxy groups.
