Optimization of the procedure for the synthesis of calcium and sodium citrate in laboratory and semi-industrial conditions / Optimizacija postupka sinteze kalcijum i natrijum-citrata u laboratorijskim i poluindustrijskim uslovima
(Association of Chemical Engineers of Serbia, 2009)
The aim of this investigation is the development of the optimal laboratory procedure for the synthesis of calcium and sodium citrate and the application of obtained results in a project for a semi-industrial installation ...
Semi-interpenetrating polymer networks of chitosan and poly(ethylene glycol) / Semi-interpenetrirajuće mreže hitozana i poli(etilen glikola)
(Association of Chemical Engineers of Serbia, 2008)
Chitosan is a natural polycationic polymer that possesses useful properties such as bioactivity, biocompatibility, non-toxicity and non-antigenicity. On the other hand, its mechanical properties are not good for some ...
The effects of zeolite and silica gel on synthesis of amylisobutyrate catalyzed by lipase from Candida rugosa / Uticaj zeolita i silika gela na sintezu amil-izobutirata katalizovanu lipazom iz Candida rugosa
(Association of Chemical Engineers of Serbia, 2008)
Lipase-catalyzed synthesis of esters has been widely investigated due to numerous advantages in comparison with the conventional chemical process catalyzed with concentrated acids since use of chemical catalysts leads to ...
Biocompatible and bioadhesive hydrogels based on 2-hydroxyethyl methacrylate, monofunctional poly(alkylene glycol)s and itaconic acid / Biokompatibilni i bioadhezivni hidrogelovi na bazi 2-hidroksietil metakrilata, monofunkcionalizovanih poli(alkilen glikol)a i itakonske kiseline
(Association of Chemical Engineers of Serbia, 2007)
New types of hydrogels were prepared by the radical copolymerization of 2-hydroxyethyl methacrylate, itaconic acid and four different poly(alkylene glycol) (meth)acrylate components (Bisomers) in a water/ethanol mixture ...
