Abstract

Proces deamalgamacije u amalgamima slitina bogatih srebrom i kositrom istraživan je metalografijom, mjerenjem mikrotvrdoće, rentgenskom difrakcijom i diferencijalnom termičkom analizom. Dobiveni rezultati raspravljeni su s gledišta regeneracije otpadnog amalgama (reciklaže, tj. obnavljanja strukture i svojstava polaznih komponenti), kao i moguće uporabe ovog procesa u metalurgiji praha.

Abstract

The X-ray crystal structure analysis of the title compound, C(17)H(30)O(8), revealed a (4)C(1) conformation of the pyranosyl ring [Cremer-Pople puckering parameters of Q = 0.568 (2) A, theta = 5.1 (2) and phi = 218 (3) degrees ]. The structure shows no deviations from the geometric parameters of pyranoside carbohydrates. The hydroxyl groups participate in O-H.O hydrogen bonds, forming a two-dimensional pattern [O.O = 2.811 (3) and 2.995 (3) A].
