标题:一种生产二乙醇单异丙醇胺的方法
摘要:本发明公开了一种生产低色度二乙醇单异丙醇胺的方法,它包括以下步骤:S1.反应容器中加入二乙醇胺和氨,搅拌均匀后,升温至40~60oc;s2.往反应容器中连续加入环氧丙烷,控制反应温度和压力,待反应完全后得到低色度二乙醇单异丙醇胺.环氧丙烷中的醛含量偏高时会导致二乙醇单异丙醇胺的色度偏高,在二乙醇胺中加入氨,使环氧丙烷中的甲醛,乙醛,丙醛等醛优先与氨反应,避免了生色物的形成,因此,本发明的制备方法可用于醛含量超标的环氧丙烷生产低色度的二乙醇单异丙醇胺;本发明的制备方法操作简单,制备方便,成本低,能有效降低了二乙醇单异丙醇胺的色度,适于工业化大规模生产.

标题:Dynamic covalent chemistry of spiropyrans for synthesis of photoswitchable photoinitiators and uses thereof
发明人:GARMSHAUSEN YVES
权利人:XOLO GMBH
摘要:The present invention relates to spiropyrans and process for the manufacture of them. In particular, a method is provided to exchange the indole and salicylaldehyde part of a spiropyran in a reversible reaction. The method is used for the synthesis of dual color photoinitiators with specific substituents and substitution patterns, which result in improved dual color volumetric printing (xolography). Furthermore, a process for locally polymerizing a starting material by dual color photopolymerization is disclosed.

标题 :Tuned synthetic dendrimer calibrants for mass spectrometry
发明人:GRAYSON SCOTT
权利人:THE ADMINISTRATORS OF THE TULANE EDUCATIONAL FUND
摘要:Provided are synthetic dendrimer calibrants for mass spectrometry. The calibrants are distinguished by their relative case and rapidity of synthesis, comparatively low cost, long shelf life, high purity, and amenability to batch synthesis as mixtures. The latter characteristic enables parallel preparation of higher molecular weight compounds displaying useful distributions of discrete molecular weights, thereby providing multi-point mass spectrometry calibration standards. Methods of making, tuning and using said calibrants are provided.
