to utilize it as an acid catalyst for the dehydration reaction.4 The use of Montmorillonite K10 is an excellent example of green chemistry as it not only shows the use of catalysts to increase efficiency but also displays a less hazardous form of chemical synthesis. The cyclohexene collected from the first experiment served as the starting material for the next reaction of the cycle in which, hydrogen peroxide (H2O2) and hydrobromic acid (HBr) were combined to generate molecular bromine in…

1.3.: Chemical structure of a, b, g CDs. The characteristic structural features of CDs are depicted in Figure 1.3. On the side where the secondary hydroxyl groups are situated, the cavity is wider than on the other side where free rotation of the primary hydroxyls…

compound including halides or nitrates but preferably metallo-organics are suitable for this process. The important control parameters are the viscosity of the solution, the pulling speed and the firing temperature. The rate of heating also needs to be controlled to avoid cracking of the films. This technique has been used commercially…

the phases and or molecular size. As a result, the components move at different speeds over the stationary phase and are thereby separated from each other. These components are separated from one another by the column packing that involves various chemical and/or physical interactions between their molecules and the packing particles. These separated components are…

2015) The final method is known as cake stalking. This is a process that attempt to create a dry solid for easy storage. “Water from the residues has been removed as much as possible to produce the dry cake.” (Xue et al. 2015) Issues with this system include potential airborne damages as “fine particulates from the…

Glenn T. Seaborg was born in Ishpeming, Sweden in 1912, into a family known publically as being intelligent. However, in 1922, the family moved to California in order to expand their opportunities. In high school, he had no interest in science. However, a science class was required for graduation. A teacher named Dwight Logan Reid is given credit for his interest in the field. Due to his family’s finances, the nearby University of California at Los Angeles (UCLA) was his only option; due to its…

MYCOCEPT (Mycophenolate mofetil) is the 2-morholinoethyl ester of mycophenolic acid (MPA). CHEMICAL NAME: 2-morpholin-4-ylethyl (E)-6- (4-hydroxy-6-methoxy-7-methyl-3-oxo-1H-2-benzofuran-5-yl)-4-methylhex-4 enoate. STRUCTURAL FORMULA: Fig: Mycophenolate mofetil MOLECULAR WEIGHT: 433.50g/mol APPEARANCE: Mycophenolate mofetil, is a white to off-white crystalline powder. SOLUBILITY: It is slightly…

Chapter 2 LITERATURE SURVEY 2.1. Characteristics of Hydrogen Sulphide 2.1.1. Physical and Chemical Properties H2S is a colourless gas characterised by a rotten gas odour which is highly toxic. It is soluble in different liquids including water and alcohols. It is typically formed under deficit oxygen conditions in the presence of organic matter and sulphate compounds (WHO, 2003). Hydrogen Sulphide is also present in the atmosphere in the range of 0.0001-0.0002 ppm though it may vary with places…

Km and Vmax determination of glucocerebrosidase towards p-NPG The Michaelis constant (Km) is a measure of the affinity of the enzyme towards the substrate, with smaller values representing greater affinity. Km and the maximum rate (Vmax) of leukocyte GCase were obtained through the Lineweaver-Burk plot (Figure 4) with artificial substrate p-NPG in concentrations from 0.71 mM to2.50 mM. Km and Vmax values for leukocyte GCase using p-NPG as substrate was found to be 12.6 mM and 333 U/mg…

wasn’t aware of. Many times I try to imagine what my future would be like and think about realistic conditions I might experience after graduation in my work as Chemical Engineer. Piyush Limbani is my cousin and is a Chemical Engineer working in his discourse community for over 3 years now. Piyush has a Bachelor of Science degree in Chemical Engineering and is now in charge of designing and processing supply material something that I would be interested in doing. John Swales is well known…
