摘要:大多数工业偶氮颜料是通过在一个罐中进行重氮化,然后在另一个罐中偶合来合成的.通过将颗粒状ptfe(聚四氟乙烯)添加到机械搅拌的nano 2水性混合物中,此两锅法已转变为一锅法.,Hcl,重氮组分和偶合组分.该方法避免了使用碱或表面活性剂溶解偶联组分的步骤.反应是快速和定量的.然后将颗粒状ptfe,废水和过量的hcl再使用11次,而不会降低反应速度和产物纯度.总共合成了22种工业颜料和3种偶氮化合物,该反应在实验室中最多可生产22.7 G产品.一些反应需要少于2当量.提出了hcl的解释和解释它的机理.此外,直径:硝基组效果是在先进的反应速率为耦合来解释差异ø-,米-和p硝基苯胺.

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.

摘要:Methods involve in-flight processing of inorganic particles synthesized within the flow. Thus, the flow extends from an inlet connected to a reactant delivery system with inorganic particle precursors to a collector. The as formed inorganic particle can be modified with radiation and/or the application of a coating composition. Additional processing steps can be introduced as desired. Suitable apparatuses for in-flight processing can be based on addition of processing elements onto an inorganic synthesis reactor, such as a laser pyrolysis reactor.

摘要:Methods disclosed herein relate to generating silk nanoparticles with a low polydispersity index (PDI). Methods include adding a silk solution dropwise into a volatile solvent that is miscible with water, thereby forming a precipitate-bearing solution and applying shear forces to the precipitate-bearing solution for a length of time sufficient to achieve evaporation of at least 95% of the volatile solvent, thereby producing a population of silk fibroin nanoparticles in water having a polydispersity index (PDI) of 0.35 or less, including but not limited to, a PDI of 0.330 or less, 0.325 or less, 0.315 or less, 0.310 or less, 0.30 or less, 0.275 or less, 0.250 or less, 0.225 or less, or 0.200 or less. Parameters related to silk fibroin molecular weight, silk fibroin concentration, shear force application, and temperature may all be modified to achieve silk nanoparticles of a particular size exhibiting particular PDIs.
