A novel Brönsted-Lewis acidic heteropoly organic-inorganic salt: preparation and catalysis for rosin dimerization.
A novel Brönsted-Lewis acidic heteropoly organic-inorganic salt has been prepared via the replacement of protons in neat phosphotungstic acid with both organic and metal cations. This hybrid catalyst, Sm0.33[TEAPS]2PW12O40, exhibited satisfactory performance in the dimerization of rosin to prepare polymerized rosin Under optimum conditions (15.0 g rosin and 5.0 g Sm0.33[TEAPS]2PW12O40 catalyst ...
متن کاملEfficient extraction of basic, neutral, and weakly acidic drugs from plasma for analysis by gas chromatography-mass spectrometry.
We describe a method for efficiently extracting basic, neutral, and weakly acidic drugs from plasma for toxicological analysis by gas chromatography-mass spectrometry (GC/MS). The 2-mL plasma sample is diluted with an equal volume of saturated NaCl containing triethylamine, 10 mmol/L, and then extracted twice with 4 mL of an equivolume solution of dichloromethane/acetone. The organic (top) phas...
متن کاملCationic surfactant modified wood sawdust for removal of acidic dyes
In this paper, application of sawdust prepared from Narra wood (SD) modified with cationic surfactant of cetyltrimethylammonium bromide (SD/CTAB) was used for removal of two typical acid dyes commercially named as Acid Green 25 (AG25) and Acid Red 14 (AR14) from aqueous solutions. The effects of experimental variables, such as pH, initial dye concentration, adsorbent dose, contact time and temp...
متن کاملWEAKLY PERIODIC AND SUBWEAKLY PERIODIC RINGS AMBER ROSIN and ADIL YAQUB
Throughout, R represents a ring and (R) denotes the commutator ideal of R. For any x,y in R, [x,y] = xy −yx is the usual commutator. A word w(x,y) is a product in which each factor is x or y . The empty word is defined to be 1. We now state formally the definition of a subweakly periodic ring. Definition 1. A ring R is called subweakly periodic if every x in R\J can be written in the form x = a...
متن کاملEffect of Remin Pro and Neutral Sodium Fluoride on Enamel Microhardness After Exposure to Acidic Drink
Background and Aim: High consumption of carbonated diet soda is the most common etiologic factor for dental erosion. The purpose of this study was to evaluate the microhardness of the enamel surface eroded by cola after treatment with Remin Pro and neutral sodium fluoride. Materials and Methods: This in vitro experimental study was performed on 20 extracted premolars with no corrosion, abras...
