查询词典 amide

We have used GC to follow up the formation of epoxy acid and established the acidify condition; we have done series of parallel experiments to better the pivotal condensation reaction between acid and amine; In the cyclization step, we use cheap and available reagent-Lithium amide , rather than expensive LiHMDS, to proceed the reaction; and at last, we introduced green reagent-ozone to clear the phenyl group of nitrogen to avoid using heavy metal reagent-CAN.

It was shown that the absorption peaks of amine and amide groups of gelatin were shifted in HDPE/PE-g-MAH/Gelatin blends because of the reaction of PE-g-MAH with gelatin. The addition of PE-g-MAH made the increase of HDPE glass transition temperature. The compatibilizing effect of PE-g-MAH was due to the crystal compatibility produced by forming the co-crystals of HDPE, PE-g-MAH and PE-g-MAH-g-gelatin. The blends of EAA and gelatin were prepared by melting process and the compatibility of the blends was also studied. The FTIR results showed that absorption peaks of amine and amide groups of gelatin were shifted in EAA/Gelatin blends.
