The Following-observing Method for Substance Flow Analysis

Lu Zhongwu

Strategic Study of CAE 2006, Volume 8, Issue 1,   Pages 18-25

Abstract: substance flow.Correspondingly, two methods for substance flow analysis were advanced : one of them is “ following-observingflow (constant output of product), but also for unsteady substance flow (increasing or decreasing outputThe following-observing model of substance flow was explained by using iron flow diagram in the lifeof indexes of lead flow.

Effects of a structurally related substance on the crystallization of paracetamol

Ali SALEEMI, I.I. ONYEMELUKWE, Zoltan NAGY

Frontiers of Chemical Science and Engineering 2013, Volume 7, Issue 1,   Pages 79-87 doi: 10.1007/s11705-013-1308-7

Abstract: Paracetamol (PCM) was crystallized from an isopropanol (IPA) solution containing various small amounts of metacetamol as an additive. The effect on the nucleation kinetics was studied by measuring the induction time to nucleation and the metastable zone width using focused beam reflectance measurements (FBRM) and attenuated total reflectance (ATR-UV/Vis) spectroscopy. Both the induction time and the metastable zone width were expressed as functions of the additive concentration. Small amounts of metacetamol (1–4 mol-%) were found to cause significant inhibition to the nucleation by extending both the induction time and the metastable zone width. A progressive change in the morphology of the paracetamol crystals from tabular to columnar habit was observed with increasing metacetamol concentration. The solvent also had a significant effect on the size of the paracetamol crystals as smaller crystals were obtained in IPA than in aqueous solution. The dissolution rate of paracetamol was improved by the incorporation of metacetamol with 4 mol-% having the most effect. A supersaturation control (SSC) approach was implemented for the PCM-IPA system with and without metacetamol in an attempt to control and obtain larger metacetamol-doped paracetamol crystals.
