Central Composite Experimental Design Applied to the Catalytic Carbon-Sulfur Bond Formation by Fluorapatite Catalyst

Central Composite experimental design applied to removal of phenanthrene and acenaphthene from soil samples

Abstract In this work, removal of phenanthrene and acenaphthene, as a representative of polycyclic aromatic hydrocarbons, was investigated from soil samples by the soil washing remediation method combined with Central Composite Design. Response surface methodology was utilized to investigate the individual and interactive effects of three variables of removal process including surfactant solut...

Metal-catalyzed carbon-sulfur bond formation.

In organic synthetic reactions, the scope and application of organosulfur chemistry have increased tremendously since sulfur-containing groups serve an important auxiliary function in synthetic sequences.1 Illustrative examples are the reversal of polarity (Umpolung), the enhancement of the acidity of C-H bonds, and the transfer of chirality from sulfur to carbon.2 On the other hand, transition...

Central composite experimental design applied to fabrication of LLDPE microporous membrane via thermally induced phase separation (TIPS) method

Approaches to catalyst discovery. New carbon±heteroatom and carbon±carbon bond formation*

Studies on the palladium-catalyzed formation of aryl amines, aryl ethers and a-aryl carbonyl compounds from aryl halides are reported. These studies range from synthetic methodology, to detailed mechanistic analysis, to new methods one can use to screen for catalytic covalent bond formation. Improved methods for formation of aryl ethers and room temperature amination chemistry have resulted fro...

Formation of Poly(vinylidenefluoride) Nanofibers: Part I Optimization by Using of Central Composite Design

Poly(vinylidene fluoride) (PVDF) nanofibers were prepared via electrospinning process. Several different factors influence on this process and application of experimental design for its optimization is of great importance. The central composite design (CCD) was used for planning and optimizing of the experiments and also, the analysis of variance (ANOVA) was employed for the statistical va...
