Is polyaluminum chloride micro-nano reactor good for organic synthesis?

Afterward, the polyaluminum chloride micro–nano reactor exhibited excellent catalytic activity (in 3 types of reactions, the best yield = 99%) and stability (yield >90% after repeated use for 4 times) in organic synthesis reactions.

What is polyaluminum chloride (PAC)?

Received 2nd November 2021 , Accepted 26th November 2021 Polyaluminum chloride (PAC) is an inorganic polymer material that has the advantages of a simple preparation process and special electronic structure. It is considered to be the most efficient and widely used flocculation material for water treatment.

Can polyaluminum chloride coagulant be used to treat petroleum wastewater?

This work investigates the potential synthesis of cost-effective polyaluminum chloride (PACl) coagulant from waste household aluminum foil and utilization for treating petroleum wastewater (PWW), especially dissolved organic compounds (DOC, like octanol–water mixture) and nonsettleable suspended (NSS-kaolin) mineral particles.

Is aluminum chloride neutralized?

Commonly, aluminum chloride has been neutralized to produce PACls. PACls typically include high levels of polynuclear aluminum hydrolysis products, such as Al 13 , , . As a polynuclear former, poly aluminum chloride (PAC) is a complex inorganic compound made of aluminum and progressive chlorination of the hydroxyl ion.

How to make poly aluminum chloride?

2.1. Preparation of poly aluminum chloride from kaolin 10 g of dried kaolin added to 35 ml of HCl (36%), sp.gr. (1.15), reflex for 3 hrs., at 150 °C, then, filtrate of the hot solution through filter paper (Whatman 40), the filtrate has animation as PAC ™.

Does initial concentration of aluminum chloride affect the yield of Al B?

As observed in Fig. 1 (a–d), the effects of initial concentration of aluminum chloride, basicity ratio, reaction temperature and time curves were steep slope and curvature, which revealed that the yield of Al b content in the PΑC species was very sensitive for these factors.
