3-(4-acetylphenyl)-6-bromo-2-(4-chlorophenyl)quinazolin-4(3H)-one (2) Compound 1 ( 0.01 mol) fused with p-aminoacetophenone ( 0.01 mol) at 160 oC in an oil bath for 2 h. Crystallized from ethanol to give redish brown crystals of 2, m.p. 210oC in 80% yield. Analysis for C22H14BrClN2O2, Calcd.: % C, 58.24; H, 3.11; N, 6.17, Found: % C, 58.31; H, 3.17; N, 6.20, IR spectrum (KBr, cm-1) showed characteristic absorption bands at 3380 (C-H aromatic), 1710 (C=O of acetyl), at 1690 (C=O of…

2.8.4 Properties The application of carrageenan as food additive depends on its performance such as forming thick solution or gels. For example, κ− carrageenan forms strong and rigid gels with potassium salts, forms brittle gels with calcium salts, clears gel with sugar addition, and exhibits syneresis. On the other hand, ι− carrageenan forms elastic gels with calcium salts, clears gel with no syneresis, and creates a gel that is freeze/thaw stable, while λ− carrageenan is not gel-forming but…

Methane is the final product of Anaerobic Digestion. A mixture of methane and carbon dioxide is called a biogas and it can be used for heating and can be used as a natural gas. Anaerobic treatment systems are divided into “high rate” systems involving biomass retention and “low rate” systems without biomass retention. High rate systems are characterized by a relatively short hydraulic retention time but long sludge retention time and can be used to treat many types of wastewater. Low rate…

Abstract 6- bromo-2-(4-chlorophenyl)quinazolin-4(3H)-one derivatives 2-7 were synthesized.. The synthesized compounds were evaluated for their anti-microbial activity using the agar diffusion technique . The tested compounds were evaluated against, Gram +ve bacteria , Gram -ve bacteria, Yeast and Filamentous Fungus. Minimum inhibitory concentration (MIC) was made in vitro for compounds which showed antimicrobial activity. Compound 3b has broad spectrum activity against Gram +ve bacteria, Gram…

differently. The alcohol in your body will metabolize depending on your body mass and the size of your liver and there’s only so much your body can metabolize each hour. There are two main enzymes that break down alcohol: alcohol dehydrogenase and aldehyde dehydrogenase. The speed of your alcohol metabolism depends on how much of these enzymes you have in your body (Hart & Ksir, 2012). Alcohol has a way of altering your brain functions by interacting with neurotransmitters. This can make you…

Coordination complex A coordination compound is the result of the reaction of lewis acid and lewis base in which neutral molecules called ligands make coordinate covalent bond with middle metal atom. Ligands have one electron pair to donate to a metal atom and are called complex agents. • Metal atoms are Lewis acids because they can accept pairs of electrons from Lewis bases. • Within a ligand, the atom that is directly bonded to the metal atom/ion is called the donor atom. • A coordinate…

There are many different methods for developing latent fingerprints. Some work better on non-porous surfaces, while others work best developing prints on porous surfaces. Some are destructive preventing testing the object for other forensic evidence while others are non-destructive. In order to make prints visible on porous surfaces, forensic scientists use one of three methods; Silver Nitrate, Ninhydrin and Iodine fuming. These three methods are known to be the most effective ways for…

common and abundant forms are fibers, sugars, and starches (nlm.nil.gov). Glucose is a common known of sugar and it is one of the standards that were used in this lab. Glucose is a 6 carbon atoms, it is classified as an aldohexose (a hexose with an aldehyde group on one end). There are also other common standard that were used in this lab is fructose. Similar to Glucose, Fructose has 6 carbon atoms, however, it is a ketohexose (a hexose with ketone group on one end) (Bruice 2011).…

Amino acids Amino acids are building block s of proteins. Each amino acid contains main three structural components. 1) Amino group 2) Carboxcilic group 3) R group Figure 1 https://www.bing.com/images/search?q=amino+acids&view=detailv2&&id=072990A13D7C6B29926E0FC3F9E9BE59C8A6322E 2016 R can be hydrogen or any other functional group .in world there are around 182-200 found to be present in nature but we can find 20 aminoacids in…

The chemistry of carbohydrates, proteins and minerals plays an important role in running the life process of human body. The chemical reactions and their role in the human body are essential as it fuels the body to carry out the life process, to keep the body healthy and to provide body with energy. Structure of Starch It is formed by units of glucose and is a homopolysaccaride. It is found in the vegetable cells and is composed of two types of homopolysaccaride; Amylopectin and amylose.…
