2024年9月15日 · Tetraethylenepentamine (TEPA, Sigma-Aldrich, CAS No. 112-57-2) was reacted with 5 mol/L aqueous HCl (Sigma-Aldrich, CAS No. 7647-01-0) to synthesize [TEPA]Cl, [TEPA]Cl 2, and [TEPA]Cl 3, which were utilized as hydrogen bond acceptors (HBAs).

2023年5月1日 · TEPA could effectively trigger the phase separation of the biphasic solvent. The biphasic solvent realized 78.1% reduction in sensible heat compared to 30 wt% MEA. The regulatory mechanism of TEPA was verified by 13 C NMR and quantum calculations.

2023年9月18日 · To probe the structure and mobility of TEPA and PEI supported in SBA-15 and link their physical properties to their gas sorption behavior, we conducted 1 H T 1 –T 2 correlation NMR studies on TEPA/SBA-15 and PEI/SBA-15 with varied weight loadings of amine.

2019年4月23日 · Distinctive features of such a structure are multifold: the highly viscous TEPA is compartmentalized into tiny droplets, achieving a high surface-to-volume ratio; the accessibility of TEPA is...

Detailed information about isolation and identification of TEPA components, CO 2 capture capacities, amine efficiencies of the TEPA-based sorbents at 40 °C and 13 C NMR, FT-IR, and GC spectra of T-BRN and T-IPZ obtained during deterioration in oxidation (PDF)

2024年4月1日 · Concurrently, another set of peaks emerged in the NMR spectrum between 35 ppm and 41 ppm and 44 ppm and 52 ppm, with these peaks attributed to TEPA–a (H +)–b (COO −).

In this work, wet-jet milling (WJM) exfoliation was used to massively produce few-layer hexagonal boron nitride (h-BN) flakes as corrosion-protection pigment in polyisobutylene (PIB)-based...

The effect of rGO-TEPA concentration on the morphology, wettability, thermal stability, cytocompatibility, cytotoxicity, and anti-biofilm activity of the nanofibrous membranes was extensively ...

我们对液态13 C NMR的仔细分析揭示了EB功能化TEPA（EB-TEPA）的胺态分布。 尽管由EB官能化引起的叔胺部分的增加减少了CO 2吸附能力，0.64EB-TEPA（即用EB功能化的TEPA / TEPA / EB摩尔比为1：3的TEPA）/ SiO 2在使用CO的连续10个吸附/解吸过程的连续循环中显示出优异的长期稳定性在干燥的CO 2 / N 2（15/85 mol / mol）进料条件下，2摆动能力为2.0 mmol CO 2 g –1。 同样，第一性原理计算通过XRD测量确定了改性TEPA分子的构型，支持了CO 2轻松进 …

A simple temperature-assisted solution interaction technique was used to functionalize and reduce graphene oxide (GO) using tetraethylenepentamine (TEPA) with less chemicals, low temperature, and...
