说明

Application

氰化四丁基胺可用作催化剂：

在质子溶剂存在下，用于脱保护脂肪族硫醋酸酯，以合成自由硫基
在三甲基氰硅烷（TMSCN）存在下，用于羰基化合物的O-TMS 氰硅化反应，以合成氰丙烷三甲基硅醚.
在乙腈的存在下，通过对β-内酰胺键裂合成γ内酰胺，进而实现β-内酰胺的环扩展.

Tetrabutylammonium cyanide catalyzes the addition of TMSCN to aldehydes and ketones

Cordoba R, et al.

ARKIVOC (Gainesville, FL, United States), 4, 94-99 (2004)

Novel reverse-phase ion pair-high performance liquid chromatography separation of heparin, heparan sulfate and low molecular weight-heparins disaccharides and oligosaccharides.

Fabio Galeotti et al.

Journal of chromatography. A, 1284, 141-147 (2013-03-05)

In this study, by using tetrabutylammonium bisulfate as ion-pairing reagent, we were able to separate all the main heparin/heparan sulfate disaccharides generated by the action of heparinases along with the main Hep tetrasaccharide possessing a 3-O-sulfate group on the sulfoglucosamine

Small-angle neutron scattering study of temperature vs. salt dependence of clouding in charged micellar system.

A J Chinchalikar et al.

The European physical journal. E, Soft matter, 35(7), 55-55 (2012-07-06)

Clouding is studied by small-angle neutron scattering (SANS) on a charged micellar system of sodium dodecyl sulphate (SDS) and tetrabutylammonium bromide (TBAB) with varying temperature and salt NaCl. We show that the clouding occurs as a result of increase in
