Critical review of relations for predicting the normal freezing point of organic compounds / Kritički prikaz modela za predskazivanje normalne temperature mržnjenja organskih supstanci
(Association of Chemical Engineers of Serbia, 2005)
This paper presents empirical relations for predicting the normal freezing point of organic compounds. Nine relations were tested with 90 organic compounds. The Meyer-van der Wyk and Kreglewski-Marano-Holder models are ...
Modern catalysis in the synthesis of some pharmaceuticals and fine chemicals / Savremena kataliza u sintezi nekih farmaceutskih sirovina i finih hemikalija
(Association of Chemical Engineers of Serbia, 2002)
Catalysis in the synthesis of Pharmaceuticals and line chemicals nowadays becomes more and more important. Synthesis that minimizes wastes is important from the economical aspect, as well as from the environmental aspect. ...
Mathematical modeling of gel drying with supercritical carbon dioxide / Matematičko modelovanje sušenja gela natkritičnim ugljen dioksidom
(Association of Chemical Engineers of Serbia, 2001)
The most complex step in the production of aerogels is the supercritical drying step, and it is therefore important to study its dynamics using mathematical models. Alumina/silica aerogel was obtained using a one step ...
Chemical stability of triple base powders and methods of examination / Hemijska stabilnost trobaznih baruta i metode ispitivanja
(Association of Chemical Engineers of Serbia, 2000)
This paper defines the term powder chemical stability and describes development of the relevant test methods. Traditional, i.e. classical, as well as instrumental test methods of chemical stability for double and triple ...
A critical review of relationships for predicting the dynamic viscosity coefficient of liquid organic compounds at saturation conditions / Kritički prikaz modela za predskazivanje koeficijenta dinamičkog viskoziteta zasićene tečnosti organskih supstanci
(Association of Chemical Engineers of Serbia, 2001)
This paper presents some empirical relationships for predicting the saturated liquid dynamic viscosity coefficient of organic compounds. Eleven models were tested using 295 experimental points for 34 organic compounds. On ...
