氨甲酸乙酯

Urethane adduct was synthesized from decarboxylated cashew nut shell liquid,hexamethylenediisocynate and polyethylglycol,which was then reacted with melamineformaldehyde resin to form aqueous coating material.

采用天然植物油、己二异氰酸酯和聚乙二醇在较温和的条件下反应，制得了水溶性的氨基甲酸酯加成物，以此和低醚化度甲醚化三聚氰氨甲醚甲醛树脂制备了水性涂料。

After acid hydrolysis of urine, primary amino acids were derivatized with ortho-phthaldialdehyde and removed from the sample by use of silica gel, followed by devivatized of hydroxyproline with 9-fluorenylmethyl chloroformate, and then injected into a C8 reversed-phase column.

采用邻苯二甲醛和芴甲基氯甲酸酯两个衍生剂，先后处理尿标本，以国产C8柱为固定相，在醋酸钠缓冲液中加入23%的乙腈作为洗脱液，3，4-脱氢脯氨酸作为内标。

Properties of frontier orbital of xanthogen formates and ethoxycarbonyl thionocarbamates, including HOMO energy, shape of HOMO and atomic HOMO density, were calculated with quantum chemistry programs GW03 and FUJISTU CAChe. According to the results, the relationship between selectivity of such two kinds of collectors and their quantum chemical indices was investigated to discuss the feasibility of applying them in screening chalcopyrite collectors.

摘 要：利用量子化学软件GW03和FUJISTU CAChe计算黄原酸甲酸酯类、乙氧羰基硫氨酯类黄铜矿捕收剂的前线轨道的性质—HOMO能量、HOMO形状以及药剂组成原子的HOMO密度，并结合这两类药剂的浮选结果研究这些量化参数与药剂选择性之间的联系，探讨这些参数作为选择黄铜矿捕收剂判据的可行性。
