两种类型的水化学是（i）在水中和（ii）在水中。对“水上”化学的基本理解是众所周知的。相比之下，“水中”化学还没有被很好地理解。胶束催化是“水中”化学的主要推动者，而基于 HPMC（羟丙基甲基纤维素）的化学是新的，因此尚未开发。此观点专门针对 HPMC 的水中化学。艾伯维 (AbbVie) 和我们的团队最近报道了水性 HPMC 中的化学/催化。使用 HPMC 进行“水化学”需要了解该技术的必要程序和限制的基本知识。因此，这个观点的重点是教育观众如何在化学催化中有效地使用 HPMC。此外，它还包括 HPMC 的粘度如何以及为何成为反应成功的关键因素。我们还列出了市售 HPMC 的各种等级的粘度，以便读者可以轻松挑选提供感兴趣材料的供应商。
The two types of water chemistries are (i) on water and (ii) in water. The fundamental understanding of "on water" chemistry is very well-known. In contrast, "in water" chemistry is yet not well understood. Micellar catalysis is a major enabler of "in water" chemistry, while HPMC (hydroxypropyl methylcellulose)-based chemistry is new and therefore underdeveloped. This perspective is dedicated to the in water chemistry of HPMC. Chemistry/catalysis in aqueous HPMC has recently been reported by AbbVie and our group. Using HPMC for "in water chemistry" requires a basic knowledge of the necessary procedures and limitations of this technology. Therefore, this perspective focuses on educating the audience about how HPMC can be effectively used in chemocatalysis. In addition, it includes how and why the viscosity of HPMC is a critical factor for the reaction's success. We also list the viscosities of various grades of commercially available HPMC, so that readers can easily pick the supplier that provides the material of interest.
