New method of synthesis of oligoetherols with carbazole ring Renata Lubczak Abstract: The new method of synthesis of multifuntional oligoetherols with carbazole ring suitable for obtaining the polyurethane foams of enhanced thermal resistance was presented. At the first step of the synthesis the carbazole was reacted with excess glycidol to obtain the product of (n +1) functionality, where n is number of equivalents of glycidol reacted with carbazole. Carbazole reacts with glycidol without…

Jessica Grandier Bio 204 section 201 Case Study 1a What are the normal values for PH, Erythrocyte count, Leucocyte count, Platelet count. ( 1 point each) The normal values for PH are 7.35-7.45, the normal erythrocyte count for males is 4.7 - 6.1*10^6 /ul million and for women it is 4.2 -5.4*10^6/ ul million, Leucocyte count is 4,800-10,00 mmm^3 of blood and normal platelet count is 150,00-450,00 platelet for microliters. 1b What are the terms used for increase and decrease in PH…

Fig 4.12 shows the comparison of product density of hydrotreated GO obtained using CAT-E and CAT-C. The density of hydrotreated GO from CAT-C at 370◦C was 0.8148g/ml whereas at the same temperature the density of hydrotreated GO obtained from CAT-E was 0.8302 g/ml despite sulphur and nitrogen in the GO has been reduced to less than 50 ppm and 1 ppm respectively. The reason for higher density would be due to higher aromatic content in the hydrotreated product obtained from CAT-E. This indicates…

In pursuit of our continued interest in the development of solvent-free and green synthetic procedures, we decided to explore the use of tartaric acid catalyst for synthesis of polysubstituted quinolines via Friedlander condensation in high to excellent yields at 70 °C under solvent-free conditions. Initially the reaction between 2-aminobenzophenone (1.0 mmol) and dimedone (1.0 mmol), as the model reaction was examined in the presence varying amount of tartaric acid as catalyst and the results…

The instrumentation of a HPLC apparatus is as shown in the diagram above. A HPLC apparatus is including a solvent reservoir, degasser, pump, injector, HPLC column, detector and data collection device. Solvent reservoir The solvent reservoir is usually a glassware or reagent bottle which contained the analytic sample. It is located at the upper part of the HPLC. It is also known as mobile phase reservoir since the sample will be moved. The flowing of the sample is depends on gravitational…

Since 1984 the legal age to drink alcohol is 21 years old. The National Minimum drinking age act prohibited people under 21 in the United States to drink alcohol. Before 1984 the legal drinking age was 18 years old. There are many pros and cons to lowering the drinking age. Alcohol poisoning, drunk driving accidents, and stupid actions while being drunk happen to 18 year olds and 21 year olds the same even with the drinking again being 21. Some pros of the minimum drinking age being lowered…

Sterile Saline (0.9% w/v NaCl) Dissolve 9.0gm of NaCl in 1000ml water and dispense 9.0ml of the solution into 20ml test tubes. Autoclave the tubes as per the validated cycle and cool to room temperature. Sterile saline with polysorbate 80: Dissolve 9.0gm of NaCl in 1000ml water and add .5gm of tween 80 to the resulting saline solution, dispense 9.0 ml of the solution into a number of 20ml test tubes.

1 Introduction Berberine (BBR), an isoquinoline alkaloid (Fig. 1), is isolated from many medicinal herbs, such as Coptidis rhizome (Coptis chinensis Franch.) and Cortex phellodendri (Phellodendron chinense C.K.Schneid.) (1). BBR has been used to treat microbial infection, diarrhea, and other gastrointestinal (GI) diseases due to its antibacterial, antidiarrheal and strong antidotal properties (2, 3). In recent years, much focus has been put on its other potential bioactivities, such as…
