Phenol‚ also known as carbolic acid‚ is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (-C6H5) bonded to a hydroxyl group (-OH). It is mildly acidic‚ but requires careful handling due to its propensity to cause chemical burns. Phenol was first extracted from coal tar‚ but today is produced on a large scale (about 7 billion kg/year) from petroleum. It is an important industrial commodity as a

of the modern lahoratory manuals are found short of an experiment on the Michael addition. (3). We describe‚ herein‚ a two-step laboratory experiment involving the Michael addition of aniline as one of the steps. The first step involves the acylation of aniline with maleic anhydride to give maleanilic acid 1. I n the second step maleanilic acid undergoes the Michael addition of aniline and cyclization to yield I-phenyl-3-pl~enylaminopyrrolidine-2‚5dione 2 (Method A). Compound 2 can also he

Introduction: Over the past three decades we have witnessed a tremendous amount of activity in the area of biosensors. Biosensors are small devices employing biochemical molecular recognition properties as the basis for a selective analysis. The major processes involved in any biosensor system are analyte recognition‚ signal transduction‚ and readout. Due to their specificity‚ speed‚ portability‚ and low cost‚ biosensors offer exciting opportunities for numerous decentralized clinical applications

2.3.2 Counter Ion “Most bacterial cell walls are charged with a negative charge‚ so most antibacterial polymers must be charged with a positive charge to facilitate the adsorption process. The composition of the counter ion‚ or polymer-linked ions‚ is used to balance the charge‚ it also affects the antibacterial activity. The counter ion has positive charge‚ which is a strong ion-pair with the polymer will inhibit the antibacterial activity because it will prevent the polymer from interacting with
