标题:通过三氮烯的温和光化学异构化来释放芳基重氮离子来修饰蛋白质
摘要:这项工作描述了苯基二氮烯基哌啶三氮烯衍生物的开发,该衍生物可以被激活以释放芳基重氮离子,用于利用光标记蛋白质.这些探针在室温下表现出显着的工作台稳定性,并且可以在生理 Ph 值下通过低强度 Uva 照射进行光致异构化.异构化后,三氮烯变得更加碱性并易于质子化以释放反应性芳基重氮离子.研究发现,与传统观测到的光解自由基途径相比,紫外光的强度和持续时间对于观测到的重氮离子反应性至关重要.三氮烯的合成效率与整体稳定性相结合,使其成为生物共轭应用中极具吸引力的候选者.三氮烯的生物正交处理用于证明蛋白质修饰的容易程度.

摘要:The present disclosure provides for enzymatic polymerization to produce polyester resins suitable for use in manufacturing toners. In embodiments, crystalline copolymers, which are polyesters, may be synthesized from lactones, cyclic anhydrides, cyclic carbonates, and combinations thereof. These crystalline copolymers, in turn, may be utilized in the synthesis of toner particles.

权利人:ROBINSON SARAH J P; ENRIGHT THOMAS E; BELELIE JENNIFER L; XEROX CORP
摘要:The methods of manufacturing a curable wax, such as an acrylate of a hydroxyl-terminated polyethylene wax having the structure CH 3 —(CH 2 ) n —CH 2 OH, where n=22-24, are disclosed. The methods may include reacting a wax having a transformable functional group and a curable compound in the presence of an organic solvent to form an acrylate. The methods may further include removing excess curable compound using hot water having a temperature of more than 85° C., and solidifying the acrylate. The methods may thereby provide safe and cost effective methods for curable wax production at large scale.

摘要:The methods of manufacturing a curable wax, such as an acrylate of a hydroxyl-terminated polyethylene wax having the structure CH3—(CH2)n—CH2OH, where n=22-24, and removing a fouled material in a reactor are disclosed. The methods may include reacting a wax having a transformable functional group and a curable compound in the absence of an organic solvent to form an acrylate. The methods may further include removing excess curable compound using hot water having a temperature of more than about 85° C., solidifying the acrylate, removing the acrylate, and removing a fouled material in the reactor by emulsification.

摘要:The present disclosure provides methods for modifying polymeric resin materials after polymerization to make fine adjustments in the chemical or physical properties of the resin, or in modifying the structure of the polymer chains. The resulting resins may be useful in forming toner particles. In embodiments, a polymeric resin may have epoxy groups added to its backbone to increase its melting point. The resulting polymer, sometimes referred to herein as an epoxidized polymer, may, in turn, be reacted with wax-like components, to increase the compatibility of the polyester with waxes utilized in forming toner particles. In other embodiments, the resulting epoxidized polymer may be reacted with components possessing carboxylic acid groups to adjust the acid value and weight average molecular weight of the resin.

标题 :Process for preparation of azo dyestuffs by coupling in presence of aromatic sulphonic acid-formaldehyde reaction product
发明人：MOLLS HANS-HEINZ; SCHIWY WILLY; HORNLE REINHOLD; NEBELING REINHARD
权利人:BAYER AG
摘要:Dyestuff dispersions and dyestuff solutions free from salt or at least having a low salt content are obtained in that the diazotization is carried out with addition of free dispersing agent acid to which, after the synthesis, either no basic agents are added or basic agents are added only up to a pH value of 3. The disclosed process gives dyestuff compositions of low salt content and results in readily dispersible dyestuffs when water insoluble dyestuffs are prepared and stable solutions when water soluble dyestuffs are prepared. The process is widely applicable and chemical constitution of the dyestuffs is conventional.
