Glycerides are fatty acid esters of glycerol; they are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils. 870-50-8, formula is C10H18N2O4, Name is Di-tert-butyl diazene-1,2-dicarboxylate. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Electric Literature of 870-50-8.
Chen, Lin;Wang, Shuangshuang;Zhang, Yingying;Li, Yuchao;Ge, Xiangcai;Li, Guang;Wang, Liping research published 《 N-Hydroxyphthalimide catalyzed hydrazination of polyethylene glycol》, the research content is summarized as follows. In this work, N-hydroxyphthalimide (NHPI) was used as catalyst to cleave C-H bonds in polyethylene glycol (PEG) backbones to generate carbon free radicals that reacted with the N=N bonds of di-tert-Bu azodicarboxylate (DBAD) to form C-N grafts (PEG-g-DBAD). Subsequently, the tert-butoxycarbonyl (-Boc) groups of PEG-g-DBAD were removed by treating with trifluoroacetic acid (TFA) to obtain hydrazino functionalized PEG (PEG-g-NHNH2). The structure of functionalized PEG was confirmed by Fourier transform IR spectroscopy (FTIR), 1H NMR spectroscopy (1H NMR), elemental anal. and size exclusion chromatog. (SEC). Thermal gravimetric anal. (TGA) and differential scanning calorimetry (DSC) were applied to investigate thermal stability and crystallization properties of the functionalized PEG. The synthesized PEG-g-NHNH2 could be used to toughen epoxy resin (EP). The results of mech. testing and SEM images indicated that the compatibility between PEG backbones and EP has been improved due to the existing of hydrazino groups. The grafted hydrazine groups could also react with 2-bromoisobutyryl bromide (BIBB) to obtain PEG-g-BIBB which initiated the polymerization of (methyl) methacrylate (MMA) by ARGET-ATRP. Thus, we presented a methodol. with high efficiency for hydrazination of PEG under mild condition, and the functionalized PEG might have many potential applications.
