Appl. Nevertheless, seven peaks are again attributed, four Lewis sites and three Brönsted sites. Propylamine is a weak base. Store cool. The quantity of acid sites obtained with this method seems low if compared to the aluminum content of the zeolite. Explain why the difference between the boiling points of nonane (151 °C) and dibutylamine (159 °C) is smaller. Scanning electron micrographs of GaPO4-LTA obtained in ethyleneglycol (left) and in water with di-n-propylamine (right). Retention indices of amines in some polar and unpolar stationary phases, Latv. twice as many as the zeolite Y coatings.

The adsorption gives access to the total quantity of acid sites and the following desorption makes it possible to distinguish between Lewis and Brönsted sites, through the detection of the iso-propylamine in the outlet gas by a mass spectrometer (m/z = 59 signal). CCRIS 4318. PSR Zinat. VII. This shows the particularity of the Ga2O3-P2O5-HF-H2O system which allowed to obtain a structure with cages. Explain why the difference between the boiling points of nonane (151 °C) and dibutylamine (159 °C) is smaller. The use of pyridine in non-aqueous medium containing ethylene glycol led to the LTA-type GaPO4 too .

VII. A certain fraction of the acid sites are located in inaccessible zones, thus these sites cannot take part in catalysis. Also, if two or more acid sites are close, one iso-propylamine molecule can block the access to the adjacent acid sites. ; Ding, S.F., Prediction of rentention idexes.
