Maximize the running of vehicles without the use of Oil • Improve the availability of fuels & minimize the cost of fuel 1.3 Biodiesel is manufacture from a chemical process which is known as transesterification. Chemically biodiesel is referred as mono alkyl esters of long chain fatty acid derived from renewable biological sources. It can be directly used in the compression ignition engine. Biodiesel fuel is a clean burning alternative fuel that comes from 100% renewable…

(IC50=3.2) had an electron rich heteroaryl amide compound attached6. From this study, it was found that increasing the steric hindrance of the substituents at the C-22 position decreased the cytotoxic activity in the A549 cell line6. Also different aryl/alkyl- substitutions6 at the C-22 position had an influence on its cytotoxic…

1-[Cyano(4-methoxyphenyl)methyl]cycloalkanol (VF-I) synthesized through the reaction of p-methoxyphenylacetonitrile and cyclohexanone using aq. NaOH and tetrabutylammonium hydrogen sulfate as PTC. NaBH4 and CoCl2 in 2:1 THF: H2O used for the reduction of VF-I to obtain 1-(2-amino-1-(4-methoxyphenyl)ethyl)cyclohexanol (VF-II). Further, venlafaxine derivative of the amino acid -carboxamide (VFCA-I toVII ) synthesized through coupling of N-Phthaloyl amino acid chloride derivative (2a-2g-…

ADVANTAGES:- *Niosomes increases the stability of entrapped drug as they are stable. * Handling and storage of niosomal formulation requires no special conditions. *Niosomes improves oral bioavailability of the drugs and enhances the permeation of the drugs through the skin because of the presence of surfactants. *They help in reaching the target site of action by various routes such as oral, parenteral,ocular ,nasal as well as topical routes such as transdermal drug delivery.…

Sejaphala M.D. Student No. 62399543 Unique Number: 770819 Introductory Microbiology MIB2601 Assignment 02 Due Date: 13 April 2018 QUESTION 1 1. Bacteria is stained using a primary stain called crystal violet and then fixed with a mordant which in most cases is iodine. While some bacteria have the ability to retain the primary stain, others discolor when exposed to the acetone and alcohol (95%). Hence, the Gram stain divides bacteria into two groups- these bacteria are grouped…

1. Introduction and background The experiment that will be conducted is the preparation of benzoic acid. Benzoic acid is a carboxylic acid and this has been established in the 16th century. The molecular structure of benzoic acid can be seen in the following figure. Figure 1 – Molecular Structure Benzoic acid is used to prepare esters with the very high boiling points and is used as plasticisers. Plasticisers are compounds that are added to plastics to…

concentrated sulphuric acid was added into cyclohexene. Explain the reason behind the reaction. Ans: The substances mix in the test tube when concentrated sulphuric acid was added into cyclohexene because they react by electrophilic addition to form alkyl hydrogen…

Americans are constantly bombarded with the guilt of having high cholesterol, without really understanding what cholesterol even is. Cholesterol is actually incredibly important in keeping the body functioning. In fact, studies have shown that too-low cholesterol levels can cause anxiety and depression, among other issues, in both men and women. (1) High cholesterol is potentially very dangerous and can even be life-threatening. Luckily, lowering blood cholesterol levels is not as hard as one…

Nanotechnology and Cancer: A Look into Better Options Since the beginning of time, human beings have been felled by disease and one of the most common killers of humans and animals as well. Until recently cancer has gone uninterrupted in its mass killing spree. Methods of treatment began to arise such as radiotherapy and chemotherapy. Now technology has advanced enough to allow nanotechnology to arise. Nano allows access to treatment and detection options that neither radiotherapy nor…

For the next two weeks, the objective of this lab is to explore EAS reactions. These reactions are possible spots on a benzene ring for substituting electrophiles due to compounds that are already on the ring. There are three types of directing substituents. The first one is a para-director which guides the second substituent on the opposite side of the benzene ring. The second director, which corresponds with para-directors, is the ortho-director. These directors place the group of atoms on the…
