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

Total Carbohydrates Using the Phenol-Sulfuric Acid Method This lab introduced the students to analyzing carbohydrate content using a spectrophotometer and phenol-sulfuric acid methods. Virginia Smith 983976633 Lab Partner: Jeff Martz Due Date: 3-22-11 Introduction The objective of this lab was to have students use a spectrophotometer to analyze the carbohydrate content in the sample. Phenol-sulfuric acid methods were also applied to

Experiment #8 – properties of Alcohols and Phenols Introduction As has been mentioned before‚ over 20 million organic compounds have been identified. If each substance had to be studied as an entity completely separate from all the other substances‚ the study of organic chemistry as a whole would be impossible; that is to say‚ even more impossible than you currently believe it to be. Fortunately‚ the subject can be organized and it is often organized around the concept of the functional group

To determine if the reaction had gone to completion‚ a Starch/Iodine test was conducted. A change in the strip to a deep blue color would signal an excess of sodium hypochlorite reagent present. An excess is the reagent symbolizes the end of the reaction because there is no longer any reactant left to consume reagent. After the reaction was deemed completed‚ the product was isolated and purified by ether extraction‚ aqueous extraction and evaporation. To determine how sodium hypochlorite acts as

Purpose This experiment deals with separating substances. The objective was to become familiar with the methods of separating substances from one another using decantation‚ extraction‚ sublimation techniques. Brief Introduction This experiment was set to teach research students different methods of separating substances from one another. Materials that are not uniform in composition are set to be impure or heterogeneous and are called mixtures. The separation of the components of mixtures is based upon

BACKGROUND :- These resins are Thermoplastic Polymers manufactured by copolymerization of cyclic terpene hydrocarbon (like Pinene‚ Carene etc.) and phenol. There are various grades of this resin with softening points ranging from 70 - 110C. These resins are compatible with Natural and Synthetic Rubbers‚ Rosin‚ Alkyd resins‚ and most of the plasticizers and waxes. Applications are in the manufacture of tubes‚ tyres‚ gaskets‚ cables‚ pressure sensitive adhesives‚ hot melt adhesives‚ surgical

INTRODUCTION: Carboxylic acids are organic acids characterized by the presence of a carboxyl group‚ -COOH. This acid acts as a weak acid‚ which can react with a strong base. Carboxylic acids form hydrogen bonds with many water molecules and are more soluble with one to four carbon atoms. Also‚ it may have an R group that consist of hydrogen or an alkyl group that changes its water solubility. Carboxylic acids with low molecular weight have odor at room temperature and higher molecular weight
