1.The paper discusses the preparation of stearic bicine diester for sizing agent and its application in paper-making.
论述了双硬脂酰取代甘氨酸酯施胶剂的制备及其在造纸中的应用。
2.Diester deoxyaconitine is very toxic.When deoxyaconitine was transformed into mono-ester aconitum alkaloids and lipo-alkaloids by human intestinal bacteria, the toxicity decreased.
双酯型的去氧乌头碱的高,当它被肠内细菌转化为单酯型脂类生物碱时会使其低。
3.Methods: Diester,diimide and dipeptide mimic compounds were synthesized by conjugated the amino groups and acid groups with diols or diacids links.
方法:通过酯化、酰胺反应由不同的二醇或二酸连接加巴喷丁巴林合成二酯、酰胺、拟肽类等化合物。
4.Conclusion Besides hydrolysis reactions, ester-exchange reactions happen for diester-aconitines and triester-aconitines in the decocting of FAK.
5.The esterification of palmic acid and 1,4-butanediol was carried out in the (DBSA)/palmic acid/water microemulsion system,resulting in the synthesis of 1,4-butanediyl diester of palmic acid.
