Applications and microwave assisted synthesis of poly(ethylene glycol) modified Merrifield resins
No full textA microwave assisted methodology was developed to modify Merrifield resins (1-2% cross-linked containing 1.0-3.5 mmol Cl-/g) with different nominal molecular weights PEG (200-1000). The synthesis was also carried out by conventional heating to assess the differences between the two procedures. The most efficient synthesis was achieved by using microwave and by using PEG with molecular weight 200 and MR 2% crosslinked containing 1.25 mmol Cl -/g. The structural elucidation was carried out using Fourier transform infrared (FTIR) spectroscopy and elemental analyses. Upon pyrolsis-GC/MS analysis of the PEGylated MR, the PEG showed the tendency to undergo thermal degradation by the loss of a smaller PEG fragments. This observed degradation of PEG was less prominent during microwave assisted synthesis compared to conventional heating, in addition to faster reaction rates and higher yields. As expected, the PEGylated MR showed improved swelling properties in polar solvents. The chemical reactivity of the PEGylated Merrifield resin was confirmed by the esterification with pyruvic acid and by the substitution of hydroxyl group using thionyl chloride. In addition, the PEGylated MR was converted into (1) polymer-supported acid/base or redox indicator by the attachment of a blue organic dye - 2,6-dichloroindophenol (DCIP) through a nucleophilic substitution reaction and (2) beta-cyclodextrin trap, a water insoluble inclusion-complex, by immobilization of beta-cyclodextrin through cross-linking with 1,6-hexamethylene diisocyanate reagent
Interview Excerpt of Mr. Donald M. Crawford, Sr.
No full text(1948-2018) Donald Mitchell Crawford, Sr. (“DC”), musician, author, and educator, was born on May 24, 1948, and was a lifelong resident of Birmingham, AL. His father and mother owned and operated “C & S Charter Tours Bus Company,” the first black-owned bus company in the state of Alabama. Crawford was a 1966 graduate of Western Olin High School in Birmingham, AL. Crawford was an outstanding drum major, playing first chair alto saxophone under the tutelage of the late Amos F. Gordon, Sr. After high school, he received a music scholarship to Alabama State University (ASU) where he earned both his Bachelor’s and Master’s Degrees in Music Education and was later inducted into the “School of Music Hall of Fame” at ASU. He was the youngest ever inducted into the Alabama Jazz Hall of Fame. He was a veteran of the U.S. Army and performed with the 291 st and 283rd Army Band in Fort Bennett, GA. DC was Band Director at Jackson Olin High School and taught in the Birmingham School System for over thirty-five years. His love for music and performing lead him after his retirement to serve as Band Director for Miles College.
Crawford is the author of “The Wheels of the Birmingham Civil Rights Movement.” This book chronicles the lives of his late father and mother, Worcy and Christine Pride Crawford, and the role he and the company played in the Birmingham Civil Rights Movement
Aminoalkylated Merrifield Resins Reticulated by Tris-(2-chloroethyl) Phosphate for Cadmium, Copper, and Iron (II) Extraction
No full textWe aimed to synthesize novel substituted polymers bearing functional groups to chelate heavy metals during depollution applications. Three polyamine functionalized Merrifield resins were prepared via ethylenediamine (EDA), diethylenetriamine (DETA), and triethylenetetramine (TETA) modifications named, respectively, MR-EDA, MR-DETA, and MR-TETA. The aminoalkylated polymers were subsequently reticulated by tris-(2-chloroethyl) phosphate (TCEP) to obtain new polymeric resins called, respectively, MR-EDA-TCEP, MR-DETA-TCEP, and MR-TETA-TCEP. The obtained resins were characterized via attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), elemental analysis (EA), and thermogravimetric (TGA), thermodynamic (DTA), and differential thermogravimetric (DTG) analysis. The synthesized resins were then assayed to evaluate their efficiency to extract metallic ions such as Cd2+, Cu2+, and Fe2+ from aqueous solutions
An efficient monitoring technique for solid-phase reactions by KBr pellets/FT-IR using methyl p-aminobenzoate synthesis assisted by microwave radiation on merrifield resin
No full textThe use of KBr pellets in infrared spectroscopy has been investigated for monitoring solid-phase reactions. Synthesis of the methyl p-aminobenzoate on Merrifield resin (MR) is described as a model for this technique, which allows the progress of its three on-bead reaction steps to be monitored throughout their duration.O uso de pastilhas de KBr em espectroscopia de infravermelho foi investigado para a monitorização de reações em fase sólida. A síntese do p-aminobenzoato de metila na Resina Merrifield (RM) é descrita como um modelo para esta técnica, a qual permite que o progresso das três etapas da síntese sejam monitoradas
