일반 설명

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for catalysis. Find details here.

18-Crown-6 is the simplest crown ether that can be prepared by reacting triethylene glycol with triethylene glycol dichloride in the presence of potassium hydroxide as base.

애플리케이션

18-Crown-6 may be used to catalyze the N-alkylation of heterocyclic compounds and allylation of functionalized aldehydes.
Additive for greener etherification using KF-alumina.
Can be useful as phase-transfer catalysts.
Phase-transfer catalyst used in a chemoselective reduction of fused tetrazoles with NaBH4 and potassium hydroxide.

기타 정보

Macrocyclic polyethers with repeating (-CH2CH2O) units. The compounds are ionophoric (form stable complexes with cations).

Environmental and health concerns force the search for sustainable super engineering plastics (SEPs) that utilise bio-derived cyclic monomers, e.g. isosorbide instead of restricted petrochemicals. However, previously reported bio-derived thermosets or thermoplastics rarely offer thermal/mechanical properties, scalability, or recycling that match

Organometal halide perovskites (OHP) are promising materials for low-cost, high-efficiency light-emitting diodes. In films with a distribution of two-dimensional OHP nanosheets and small three-dimensional nanocrystals, an energy funnel can be realized that concentrates the excitations in highly efficient radiative recombination
