Formation of Ketoprofen-Malonic Acid Cocrystal by Solvent Evaporation Method

Formulation and characterization of ketoprofen embedded polycaprolactone microspheres using solvent evaporation method

The purpose of this study was to prepare polymeric microspheres containing Ketoprofen (KFN) by single emulsion [oil-in-water (o/w)] solvent evaporation method. Polycaprolactone (PCL), biocompatible polymer, was used for the preparation of sustained released microspheres of KFN. A Plackett–Burman design was employed by using the Design-Expert® software (Version9.0.3.1, Stat-Ease Inc., Minneapoli...

Porous Fiber Formation in Polymer-Solvent System Undergoing Solvent Evaporation

Preparation of Eudragit E100 microspheres by modified solvent evaporation method.

The objective of this investigation was to develop the hollow microspheres as a new dosage form of floating drug delivery system with prolonged stomach retention time. Hollow microspheres containing ranitidine hydrochloride were prepared by solvent evaporation method using Eudragit RLPO dissolved in a mixture of dichloromethane and ethanol. The maximum yield and drug loading amount of hollow mi...

‏‎suppression of coke formation in thermal cracking by coke inhibitors‎‏

‏‎the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

Oscillatory Oxidation of Malonic Acid by Bromate

In earlier communications we described the re­ sults of an investigation of the main products of the oscillating oxidation of malonic acid by bromate 1. The products were identified as monobromomalonic acid, dibromoacetic acid and C02 . Also, the relative quantities of the two organic products were deter­ mined. Current hypothesis on the mechanism of the reac­ tion pathway under oscillating con...
